What is a flame arrester and what is its primary function in industrial applications?

A flame arresters a safety device that is fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of flame in the event an ignition takes place.

Flame arresters are typically used wherever there is the potential for an explosion arising from flammable gas or vapor being mixed with air. Accidental ignition of a flammable mixture will result in a flame that will travel through the unburnt mixture until the fuel is consumed by the reaction.

How does a flame arrester work to prevent the spread of flames?

Flame arrestors stop the flame propagation from entering through an opening. The device contains an assembly of perforated plates, slots, screens, etc. enclosed in a case or frame that will absorb the heat of a flame entering and thereby extinguish it before it can pass through.

What are the main components of a flame arrester and their functions?

The portion of a deflagration arrester or detonation arrester comprised of parallel spaced plates, packed ceramic or steel bed, stacked or rolled expanded metal or crimped metal windings. The element provides the heat sink and mechanical barrier to flame passage.

A flame arrester functions by absorbing the heat from a flame front thus dropping the burning gas/air mixture below its auto-ignition temperature; consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element.

What materials are typically used in the construction of flame arresters to ensure durability and effectiveness?

The arrestor is generally made of wound crimped metal ribbon. The metal absorbs the heat from the flame passing through it. This reduces the temperature of the flame to below its autoignition temperature at which point the flame goes out.

What are the common maintenance procedures for flame arresters to ensure they function correctly?

• Check the arrester is correctly installed. In accordance with the flame arrester’s operating conditions.
• Ensure that no modifications have been made to the arrester without the manufacturer’s written consent.
• Damaged flame arresters must be taken out of operation and repaired or replaced.
• Only the original manufacturer’s spares can be used in flame arresters. If obsolete (ie pre-ATEX), the whole unit will need to be replaced.
• Check flame arrester is secure within the pipework and not subject to undue strain.
• Any openings (drain ports) are securely sealed with gas-tight fittings.
• Tighten all fasteners to required torque.
• Make accurate records of work carried out.

How can flame arresters be tested to ensure they are working properly and within specifications?

Deflagration, Detonation and explosion tests for flame arresters are performed using propane. Some flame arresters pass detonation test but fails in deflagration test. If the process gas increases the rate of combustion, additional tests using the specific process gas are warranted.

What are the common failure modes of flame arresters and how can they be mitigated?

The failures of flame arrestors are typically in four areas: arrestors used under conditions that exceeded their test limitations, arrestors not subjected to any official testing (hence test limitations were not known and likely inadequate for the application), arrestors failing due to their channels being distorted by the flame front overpressure, and failures due to structural or design flaws that allowed a flame pathway through the element. A fifth failure mechanism would be foreign material fouling the arrestor flow channels. Arrestors do fail, so experience data was sought to quantify a failure on demand value.

What safety considerations should be taken into account when installing and operating flame arresters?

The flame arrestor is typically installed about 30 pipe diameters or 5 m upstream of the vent tip. Velocity flame arrestors must not be too far from the ignition source otherwise the flame that is traveling backward may accelerate such that its velocity is sufficient to pass through the arrestor.

What is a Venturi tube and what is its primary purpose in fluid measurement and control?

A Venturi tube is a short pipe with a narrow and restricted inner surface. It is typically used to calculate fluid flows and as a functional pump.

This principle states that within a specified flow field, a decrease in pressure occurs when there is an increase in velocity. The pressure difference described by the Venturi effect is utilized in many different devices. An apparatus known as a Venturi tube is the foundation for such device designs.

How does the Venturi effect work and how is it utilized in a Venturi tube?

The Venturi effect is named after the Italian physicist Giovanni Venturi. The Venturi effect occurs when a fluid, such as a gas or a liquid, flows through a constricted section of a pipe or a tube. When a fluid passes through a narrow section of the pipe, its speed increases, while the pressure decreases. This happens because the fluid molecules must squeeze through a smaller space, causing them to speed up. According to the principle of conservation of energy, the total energy of the fluid must remain constant. So, as the fluid’s speed increases, its pressure decreases to compensate for the energy change.

This change in fluid velocity and pressure has practical applications. One notable example is the Venturi tube, a device that utilizes the Venturi effect to measure the flow rate of a fluid.

What are the main components of a Venturi tube and their functions?

Components of Venturi Tube:

Converging Part: As water flows through the cone, its surface area diminishes. As a result, the pressure drops and the speed of the water’s flow increases.

Throat Diameter: Because the area of a throat diameter is constant while water flows through it, the speed and pressure are likewise constant.

Diverging Part: As water passes through the cone, the area expands, causing the speed and pressure to drop.

What materials are typically used in the construction of Venturi tubes to ensure durability and accuracy?

Venturi tubes and Venturi nozzles can be supplied in a wide range of material grades. Machined devices can be manufactured from barstock, or forgings. Standard materials include ASTM A182 F316 & F304 Stainless Steels, ASTM A182 F11 & F22 Chromium Steels and ASTM A105 Carbon Steel Standard materials for fabricated devices are ASTM A240 316/L Stainless Steel and Carbon Steel.

For applications requiring high accuracy flow measurement, Venturi tubes can be individually calibrated, using water, air or natural gas, to obtain accurate discharge coefficients for the device over a range of Reynolds numbers. There are other testing methods include dyepenetrant inspection, hydrostatic pressure testing, radiographic inspection, magnetic particle inspection and positive material identification. ASME IX welding procedures and qualifications in common and exotic materials are also available. Various heat treatments, including NACE MR 0175, can also be provided.

How does the design of a Venturi tube affect its pressure drop and flow measurement accuracy?

As the venturi’s volumetric flow rate is constant throughout, the fluid’s linear velocity as it passes through the throat, which has a smaller diameter, must increase for the conserving energy, among the conservation equations, to result in a decrease in pressure.

A Venturi tube is a kind of differential pressure flow meter that calculates fluid flow by determining the pressure difference between two points in a pipe. Constricting the pipe’s diameter results in an increase in flow velocity and a corresponding pressure drop, which is what produces this pressure difference. The flow rate can be calculated using these variations in the fluid flow.

Pressure vacuum relief valve is designed to protect your tank from damage created by overpressure or excessive vacuum.

Pressure / vacuum relief valves are used extensively on bulk storage tanks, including fixed roof tanks with floating covers, to minimize evaporation loss. The valves prevent the build-up of excessive pressure or vacuum which can unbalance the system or damage the storage vessel.

A Pressure Vacuum Relief Valve plays a fundamental role in controlling the pressure and vacuum levels in a storage tank, thereby preventing the catastrophic implications of a tank over-pressurization or vacuum collapse. Additionally, these valves prevent evaporation losses, minimise product contamination, and protect the environment from hazardous vapour emissions.

How does a pressure vacuum relief valve operate to maintain safe pressure levels and prevent damage to the system?

A Pressure Vacuum Relief Valve plays a fundamental role in controlling the pressure and vacuum levels in a storage tank, thereby preventing the catastrophic implications of a tank over-pressurization or vacuum collapse.

What are the main components of a pressure vacuum relief valve and their functions?

It’s essential to understand their components. These valves typically consist of elements such as the valve body, actuator, control element, and sensing mechanism.

• Breathing in: While the tank is being emptied, the PVRV breathes in to equalize the pressure inside and outside the tank, protecting it from a vacuum.
• Breathing out: When the tank is being filled, the PVRV allows air to escape to prevent excess pressure from causing the tank to swell.

How can pressure vacuum relief valves be tested to ensure they are working properly and within their specifications?

• Operate-in-place test: If the valve has never been tested before, lift the test lever. If the valve is stuck, remove the equipment from service until it can be repaired or replaced.
• Bench test: Shut down the facility’s system and remove all pressure relief valves. Then, transport the valves to a lab for testing and repairs.
• Set pressure test: After the set pressure test, perform a leak test by maintaining the test pressure at 90% of the set pressure. Then, count the number of bubbles produced per minute.
• Water heater test: Open the valve slightly with a bucket underneath to catch any dripping water. If you can see or hear water and gas escaping, the valve is working properly. Don’t force the valve open if you feel resistance.

What are the common failure modes of pressure vacuum relief valves and how can they be prevented?

• Contamination: Fluids can contain contaminants that can damage the valve’s internal components or sealing surfaces, or get lodged inside the valve. This can prevent the valve from closing, which can cause the system to lose pressure and functionality.
• Damage: Over time, the valve can become damaged or eroded by dirt and debris, preventing it from fully closing. This can cause the valve to chatter, which means it’s not fully open but is rapidly opening and closing.
• Leakage: Leakage can occur when debris or scale gets caught between the valve disc and seat’s sealing faces. It can also happen if the spring adjustment mechanism loosens during operation, causing the valve to continuously open.
• Wrong calibration: If the valve isn’t adjusted to the correct set pressure, it may cause early releases

To prevent failure, you can:

• Protect against contamination: Incorporate adequate protection against contamination upstream of the relief valve.
• Adjust the valve: Make sure the valve is adjusted to the correct set pressure. If the plant design changes, you may need to adjust the valve’s set pressure to align with the system’s new normal operating pressure.
• Inspect and maintain: Inspect and maintain the valve according to the manufacturer’s instructions.

What safety considerations should be taken into account when installing and operating pressure vacuum relief valves?

Lifting and carrying: If the valve has a handle or lever for manual operation, do not use it to lift or carry the valve. Testing: It is highly recommended to have a certified technician test a safety valve or pressure relief valve’s set pressure and seal tightness before installation.

THERMOCOUPLE:

Thermocouple, a sensor that is used for measuring temperature. This design of the sensor consists of two dissimilar metal wires which are joined together at one end, connected to an instrument that can accept a thermocouple input and measure the reading.

They sense the temperature, and the temperature is further measured by other instruments after sensing it. As they convert a non-electrical quantity (temperature) into voltage (electrical quantity) so they are transducers also. Since the do not require any external power source to operate, so they are active transducers.

The conventional thermocouple is used with an outer protecting tube or thermowell to protect it from aggressive and corrosive process conditions.

The thermocouple working principle is based on the Seeback Effect. This effect states that when a closed circuit is formed by jointing two dissimilar metals at two junctions, and junctions are maintained at different temperatures then an electromotive force (e.m.f.) is induced in this closed circuit. The amount of induced e.m.f. is different for different metal combinations and is proportional to the temperature difference of the junctions. This is the basic thermocouple working principle.

Advantages:

• They follow the temperature changes with a small time-lag. So, it can be used in applications where very rapid changes in temperature take place. It responds to those changes very quickly.
• These are very convenient for measuring the temperature at one point in any apparatus or setup.

RESISTANCE TEMPERATURE DETECTOR (RTD):

A Resistance Temperature Detector (also known as RTD) is an electronic device used to determine the temperature by measuring the resistance of an electrical wire. This wire is referred to as a temperature sensor. If we want to measure temperature with high accuracy, an RTD is the ideal solution, as it has good linear characteristics over a wide range of temperatures.

Advantages:

• High accuracy
• Low drift
• Wide operating range
• Suitability for precision applications.

RTDS VS THERMOCOUPLES

The two most common ways of measuring temperatures for industrial applications are with resistance temperature detectors (RTDs) and thermocouples. The choice between them is typically determined by four factors;

Temperature

If process temperatures are between −200 and 500 °C (−328.0 and 932.0 °F), an industrial RTD is the preferred option. Thermocouples have a range of −180 to 2,320 °C (−292.0 to 4,208.0 °F),[9] so for temperatures above 500 °C (932 °F) it is the contact temperature measurement device commonly found in physics laboratories.

Response time

If the process requires a very fast response to temperature changes (fractions of a second as opposed to seconds), then a thermocouple is the best choice. Time response is measured by immersing the sensor in water moving at 1 m/s (3.3 ft/s) with a 63.2% step change.

Size

A standard RTD sheath is 3.175 to 6.35 mm (0.1250 to 0.2500 in) in diameter; sheath diameters for thermocouples can be less than 1.6 mm (0.063 in).

Accuracy and stability requirements

If a tolerance of 2 °C is acceptable and the highest level of repeatability is not required, a thermocouple will serve. RTDs are capable of higher accuracy and can maintain stability for many years, while thermocouples can drift within the first few hours of use.

Bliss flow systems Group, the leading supplier & distributor of Flame Arrester technology is providing you with this useful guide to deflagration and detonation pipeline explosions.

When the gas is ignited the flame begins to accelerate. This acceleration results in the build-up of a pressure wave ahead of the flame.

Given enough run-up distance, this pressure wave can build into a shock wave as the flame speed reaches sonic velocity. This first phase is known as deflagration.

Once the shock wave reaches a pressure to auto-ignite the gas through which it is traveling the flame front and shock wave couple together forming an unstable detonation.

This deflagration to detonation transition (DDT) is the most severe phase of a pipeline explosion, which can generate flame speeds of >3000m/s and high pressures, over 100bar in some cases.

In short, the deflagration Flame Arrester is designed to stop the initial phase of the explosion and is shorter and lighter than the unstable detonation arrestor, but the Deflagration Flame Arrester has restrictions on its placement within the pipe work regarding distance from the source of ignition.

Explosion characteristics

If you’re unsure about Deflagration and Detonation Flame Arrester, this brief guide to explosion characteristics is designed to help. Of course, for further advice or clarification in any way, please get in touch with one of our experts.

Maintenance and Health & Safety law

HS(G)158 states, “Health and safety law requires that plant and equipment are maintained in a safe condition. It is essential that Flame Arresters are well maintained. They should be covered by a program of regular inspection and maintenance so they continue to be effective.”

It also goes on to say, “Keep records of the specification of each arrester, its location, and its maintenance history.” These records help to identify if the arrester is suitable for the media that it is protecting.

Should the process conditions be changed it can then be easily identified if the Flame Arrester fitted remains suitable for the new conditions.

So how can Bliss flow systems help?

Many issues can be identified easily through simple inspection regimes but all too often Flame Arresters are not serviced regularly.

Bliss flow systems assist with all aspects of flame arrester effectiveness, from initial inspection reports to ongoing maintenance or simply the supply of spare parts.

Standards Compliance

All Bliss flow systems Flame Arresters have been tested and certified in accordance with national or international standards. Actual device performance is verified in the Bliss flow systems state-of-the-art in-house test facility.

HOW A FLAME ARRESTER PROVIDES PROTECTION FROM EXPLOSIONS

Whether you work in oil and gas, petrochemical, bio-fuels, or power generation, having explosion protection equipment, such as a Flame Arrester, is vital to both safety and business continuity.

You only have to look at the news. In recent years catastrophic accidents have occurred at the Stanley Refinery in Ellesmere Port, at Bunce field in Hamell Hampstead, and in Ingolstadt, southern Germany. However, the good news is that thanks to our range of patent-protected Flame Arresters and advanced flame-arresting technology and expertise,

We have simplified the process of protecting your assets against explosions and their tragic consequences.

Types of flame arrester

Bliss flow systems supply and arranges the installation of the three main types of Flame Arrester: (1) End-of-Line Deflagration Flame Arresters, (2) In-Line Deflagration Flame Arresters, and (3) In-Line Detonation Flame Arresters. Our Flame Arrester are designed to meet current legislation, ATEX regulations, and all relevant ISO standards in order to ensure the safety and protection of process equipment, operators, and the environment.

Flame Arresters are often used in combination with a Pressure Relief Valve. For example, circumstances can arise where, even though a fire is contained near a storage tank, the extreme heat given off can cause the pressure inside these vessels to increase beyond their design limits. The resulting failure, due to the lack of correct equipment installation, has often given rise to disastrous consequences.

A Flame Arrester, and correctly sized and installed Emergency Relief Vent, serve to provide maximum protection in the most arduous circumstances.

Irregular or inadequate inspection and maintenance increase the chance of failure

As is true for all safety equipment, Flame Arresters can cease to function if they’re not correctly specified or installed in the first place, or poorly or inadequately maintained thereafter.

Accordingly, we recommend that Flame Arresters and other safety devices should be inspected at least annually and more frequently where operating conditions dictate increased maintenance.

What is a centrifugal pump?

A Centrifugal Pump is defined as a hydraulic machine that changes mechanical energy into hydraulic energy by the use of centrifugal force acting on the fluid. This is a machine that uses rotation to enforce velocity on a liquid, the velocity will then be converted into a flow. Every centrifugal pump is made up of mechanical components that make the operation of the pump possible. Centrifugal pumps are commonly used in various industries for fluid transportation.

They work by converting rotational energy into kinetic energy, propelling the fluid through the pump. These pumps are efficient, reliable, and suitable for a wide range of applications such as water supply, wastewater treatment, and chemical processing.

Operating Principle:

Centrifugal pumps work to produce flow or raise a fluid from a lower level to a higher level. The working of these pumps is based on a straightforward mechanism. A centrifugal pump turns rotational energy coming from a motor into energy in a moving fluid.

The two main components responsible for this task are the impeller, and the casing, both of which belong to the portion of the pump called the wet end.

Smooth Flow — Centrifugal flow is laminar and non-pulsating allowing them to be used with flowmeters easily.

Low Maintenance & Easy to maintain — Due to their simple uncomplicated design, they are often maintained without special tools or equipment.

Efficient — As the internal elements are free to rotate, they are very efficient when handling low-viscosity fluids

Versatile — They can be designed to handle a multitude of liquids and solids by changing the materials of certain parts, or impeller design.

Low Cost — Due to their simplicity of design and wide availability, they are one of the lowest initial costs of pump. If specified correctly they can also provide the lowest lifetime cost for an application.

Low Infrastructure costs — As Centrifugal pumps can be run against a closed valve for short periods without damage, additional accessories such as pressure relief valves and other devices are not required.

Uses for Centrifugal Pump

Now that you have understood the basic working principle let’s learn about its uses. You can find centrifugal pumps being used in

1. Networks for treating wastewater
2. Irrigation
3. Municipal facilities
4. Power stations as well as gas and oil sectors to remove oil, dirt, slurry, and other materials.
5. Manufacturing industries

Different Centrifugal Pump Types

Centrifugal pumps can be classified using a variety of methods, including purpose, impeller types, construction codes, numbers, and so on. Here’s a summary of the most common classification systems for centrifugal pumps.

1. Radial pumps, axial pumps, and mixed pumps are classified based on the kind of flow they produce.
2. Single-stage and multi-stage pumps are classified based on the number of stages they have.
3. Single-volute pumps and double-volute pumps are categorised based on their volute types.
4. Single-suction and multiple-suction pumps are categorised based on the number of suctions of the pump.
5. Vertical-shaft pumps and horizontal-shaft centrifugal pumps are classified based on their shaft orientation.
6. Overhung impeller pumps and between-bearing pumps are both classified based on their impeller position.

Benefits of Centrifugal Pumps

The benefits of centrifugal pumps include:

• There is reduced friction in the pump.
• Magnetic coupling breaking the pump will not overload and will also not get damaged.
• Corrosion Resistance — the pumps allow processors and manufacturers to transfer different types of fluids, even those that can quickly corrode the other pumps. The pumps even when used extremely well can offer a long service life. The pumps are able to withstand corrosive materials.
• Energy Efficiency — Centrifugal chemical pumps rank high in energy efficiency in comparison to all the other pumping technologies. Their efficiency reduces costs both over the life span and in the short term of each unit.

A centrifugal pump is a machine that changes kinetic energy into the fluid’s pressure head. The external power from a diesel generator or electric motor then turns the pump impeller. Under the influence of the centrifugal force, the fluid enters the impeller reaching its tip and leaving the volute casing. There are many types of centrifugal pumps for example chemical pumps, vertical pumps, and trash pumps to mention only a few. They can be classified according to flow type), based on the number of stages (single-stage and multi-stage pumps), and also on the type of volute (single and double volute).

Mechanical Trap: This range of steam traps operates by sensing the difference in density between steam and condensate. Sub Groups are Bucket type, Open bucket, Inverted bucket with lever, without lever Float type, Float with lever, Free float

Thermodynamic Trap: This range of steam traps operates by sensing a difference in thermodynamic properties between steam and condensate. Thermodynamic steam traps rely on the fact that hot condensate, released under dynamic pressure, will flash off to give a mixture of steam and water. Sub Groups are Disc type Impulse type Labyrinth type Orifice type

Thermostatic Trap: This range of steam traps operates by sensing a difference in temperature between steam and condensate. Sub Groups are Bimetallic-type Metal expansion types

Advantages

Efficient steam trapping will result in optimum efficiency and will achieve the following:

1. Fast heat-up of heat transfer equipment
2. Maximum equipment temperature for enhanced steam heat transfer
3. Maximum equipment capacity
