The fuel gas often in use for industrial or commercial purposes does pass through a pipeline or some piping structure.

Consequently, the fuel gas is liable to get infiltrated with several kinds of contaminants.

As a result, the fuel gas filter comes in handy for the point-of-use filtration of the impure gas.

The fuel gas filter traps, separate, filters, coalesce, and expels both the particulate and liquid contaminants present in the fuel gas.

Besides, the solid particulate contaminants likely present in the fuel gas comprises of dust particles, rust from gas pipes, and pipeline scales.

Elsewhere, the liquid contaminants probably present in the fuel gas usually consists of moisture-related vapor and particles.

All those contaminants have varied particle sizes.

Such kinds of contaminations are liable to impairing the mechanical integrity of the downline gas-consuming systems.

Thanks to the filter, you avert potential pre-mature mechanical failure of your underlying system’s parts when you use a fuel gas filter.

The wide spread associated instrument failure as a likely cause of impure fuel gas includes but not limited to the following: excessive wear of valves, plugging of burner tips, amongst others.

The final result of using a fuel gas filter is optimal equipment health.

Coalesce filter

The fuel gas filters are the top tier category of equipment.

They have got outstanding characteristics to enhance their performance and levels of usage in their applications.

It is worth noting that you can customize quite a few features of the filter system to conform to your unique application.

However, the following are the basic features of a typical fuel gas filter.

· Skid Mounted

Nowadays, most manufacturers prefer installing the filtration system on the skid platforms.

Skid-mounted filtration units will readily fit in whatever kind of site you have for your gas processing facility.

Coalesce skid

Besides, the unit system is stand-alone.

However, you should note that the skid mounted units only come under the discretion of the buyer.

And in such cases, the manufacturer will guarantee the initial adherence of the skid unit to your application requirements.

· Rate of Flow Equipment

The fuel gas filter comes complete with different flow control gadgets, the common ones, including the functional valves.

These sets of valves are adjustable to control the extent of the gas inflows into the filtration chamber.

Precisely, the combination of valves being the inlet and outlet valves.

· Long-lasting Internals

The materials of the filter elements of the fuel gas filter systems are renowned durable materials such as fiberglass or stainless steel material.

Besides, the material type directly translates into the durability of the system.

· Associated Performance Devices

The fuel gas filter system also features several kinds of already installed operational gadgets that effectively enhance the general performance of the system.

They include pressure indicators, switch buttons, power switches, pressure transmitters, etc.

All these complementary devices, apart from being critical in the workability, also creates a user-friendly operation.

· Effective Filter Elements

Since the actual filtration occurs in the Filter elements, they are therefore highly efficient and essential components of the fuel gas filters.

· A Wide Variety of Flanges

Such as the blind flange that provides more convenient and automatic access to the filter chambers and interiors, especially during the replacements of the elements.

· Quick to Open Closure

That hugely reduces the period for cleaning and maintenance.

It eliminates the need for frequent maintenance; instead, it increases your production time and eventually saves you lots of money.

With a top-notch filter, you are guaranteed an excellent filtration efficiency.

Regardless of presumably high efficiency, the degree of efficiency varies with two significant aspects.

These include the particle size of the contaminants and the technical specifications of the machine.

Fuel gas filter system

For most filtration units, the efficiency level varies according to the contaminant sizes.

It means that when you are dealing with an outrageously impure gas majorly comprising of fine particles, expect the efficiency of the machine to decrease.

Conversely, the effectiveness of the filter tends to increase when filtering large-sized particles.

Most importantly, to verify the efficiency of the machine always seek reference to the technical specifications of the equipment.

Despite all that, some filters will still have varying practical efficiencies even under constant application and possession of similar technical specifications.

That is why you should as well take note of the manufacturer’s brand – the level of expertise vary among manufacturers.

With that information, you will undoubtedly encounter maximum fuel gas filtration efficiency of 99.9% to about 80%.

All the segments of the fuel gas filters are essential in the general performance and functioning of the filtration process.

Therefore, before kicking off your operation, you must confirm the operational basis of every section.

Above all, remember that the details about your machine parts will be available in the technical manual of the equipment- so you have to acquire it.

Nevertheless, the following are the conventional parts of any fuel gas filter.

Filter elements–available for materials of fiberglass or stainless steel throw away cartridges suitable for normal to high or low-temperature designs.

Connecting appliances– as a means of attaching several different components of the machine, the connecting elements will be diverse.

They should conform to the underlying needs of your application.

More often, the connections link the elements by transferring and linking intercommunications amongst themselves.

The filters do also have flexible connections.

Perhaps you will note the following connecting appliances depending on your filter:

• Flanges
• Transfer valves
• Weld-on ends
• Ball valves
• Needle valves
• National pipe thread seals
• Optical connections
• Inlet-outlet-drain
• Vent connections, etc.

Auxiliary Instruments– which include the differential pressure measurement devices and systems such as pressure indicator gauges, level gauges,

Filter Housing–the exterior cover of the filtration system usually comprises of either carbon steel material (varying grades) or stainless steel material(different categories).

Non-welded option for housing is also acceptable.

Optional Preliminary separation devices – Such as cyclone, demister, or cyclone demister.

Optional equipment: You can consider cover lifting, pivoting mechanism, cover safety devices.

Select accessories – the fuel filters may come pre-installed with a wide range of unique fixtures.

Some of them include pre-separator for liquid minimization, liquid intensity switches, magnetic level indicators, Bull’s eyes, adjustable fluid reservoir.

The designs of the fuel gas filters entirely rely on your needs and specific application demands.

Consequently, you may incorporate additional designs or perhaps modify the already manufactured fuel gas filter to suit your facility needs.

Nevertheless, take a look at the following designs considerations:

• Non-welded fuel gas filter systems.
• Wide variety of capacity sizes ranging between 2ʺ to 8ʺ for small ratings, the bigger ones have larger diameters.

A standard design for the fuel gas filter consists of the primary inlet chamber with filter elements.

However, the secondary exits are the outlet nozzles, which provides passage for pure quality fuel gas.

At the extreme end of the filters are the end closures, either quick opening closures or blind flange.

In regards to the support, the filters may have the skids, integral saddles, support legs or skirts.

We can widely classify fuel gas filters according to the configurations of the fuel gas filters.

In regards to the design configurations, the fuel gas filters are available in Duplex and Simplex configurations.

· Duplex Fuel Gas Filters

Duplex gas filter system

The duplex is the types of filters that comprise of dual single filter chambers interconnected with switching valves and plug system.

Also, the double design structure of the filter offers a large surface area for filtration, which thus exhibiting a massive filtration scope.

Besides, the dual chambers function independently during filtration.

It, therefore, means that even if one compartment breaks down, you simply switch operation to the other standby chamber for continued service.

Normally, the duplex filter thus guarantees continuous filtration operations no matter the situation without any lapse.

Ultimately, the filter configurations do not allow any slight downtime during maintenance or basket screen cleaning.

Above all, the changeover between the chambers is a straightforward process.

You instantly change over with a single operation or by even turning the levers.

The duplex filter configurations also have got a diverter plug that allows the flow medium to flow either through the right or left chamber.

· Simplex Fuel Gas Filters

Simplex gas filter system

Unlike the duplex configurations, the simplex configuration is a type of filter that consists of one primary unit chamber for filtration operation.

The simplex structure is simple without any kind of sophistication.

Here, the fuel gas majorly flows via the single chamber while the contaminants get trapped and eliminated; after that, the pure gas proceeds.

Due to the design consideration, the filter elements are easy to remove and replace.

Also, the simplex configurations filters are also available into two major filter types, i.e., basket type filters and the Y-type filters.

Gas filter element

Since the filtration process is purely technical and a fuel gas filter is a robust machine, you should definitely reconsider the material structure.

The material of the filter directly or indirectly impacts the filters’durability, operational basis, and efficiency.

Again, the best material types include carbon steel, stainless steel, and low-temperature steel.

Also, stainless steel material structure is capable of withstanding immense pressure and force.

Besides, the material is mostly resistant to corrosion and contamination.

Material grit is also suitable for effective cleaning procedures and maintenance.

Similarly, carbon steel is another suitable material which suits filters that often experience high rates of pressure and temperature conditions.

Above all, carbon steel is substantially resistant to thermal and mechanical shocks.

Low-temperature steel is likewise another suitable material that comfortably sustains filtration in elevated pressure and temperatures.

Please note that you can request the inclusion of any additional feature or component on your fuel gas filter, depending on your unique applications.

The optional equipment includes the following:

• The differential pressure instrumentations: Gauges and pressure indicators appliances.
• Pressure safety valves.
• Thermal relief valves
• Level gauges
• The base frame/ skid.
• Special tag plates

The transfer valves are particular types of equipment that guarantee a continuous flow of gasses through the filter system without interruption.

They ensure consistent flow and regulation of pressure drop by assuring integral sealing.

The commonly available transfer valves range from ¾ to the 8-inch sizes with flange variations of 150, 300, 400, 600, 900, 1500, and more.

The transfer valves may also come furnished with distinct joint flanges, spring-loaded pad, and a shaft of O-ring seals.

For turning mechanisms of the transfer valves, you can select between a handle system, actuator, or worm gear.

The standard application of the transfer valves is in the duplex fuel gas filters to guarantee consistent flow rates.

The technical specification will give you a full and detailed explanation of the specs of the equipment.

The outlined sets of data in the document include the material structure, design, product details, servicing, troubleshooting, and sometimes maintenance.
