Guide to Fuel Gas Coalescers – How it Works and Why You Should Install it?

Coalescing gas filters are used to separate oil and water particles from a natural gas stream using high-efficiency components for diverse applications. Understand how it removes impurities and serves the purpose of separating particulate components of mixtures. Read on to learn more about coalescing filters to make an informed decision.

The presence of ethane, water vapor, CO2, and other impurities in industrial fluids can affect the precision of the filtration system and overall quality control. A coalescer filter is an industrial device used to separate fluid mixtures at similar efficiencies. It can be used in several industries, such as oil and gas and chemical plants.

Having water in fuel gas will directly impact its combustion and delivery of the amount of energy needed. The fuel gas coalescers remove solid and liquid contaminated elements from the gas fuel that is used to power engines, burners, turbines, and compressors. This can further help provide quality fuel gas for the optimal protection of injectors and other related elements from potential damages.

What is Fuel Gas Coalescer?

It is an effective device to remove solid and liquid impurities from gas fuel to deliver clean, pure, and dry gas to meet customer needs. Coalescence is a process where fluid molecules come together to create a large whole. This equipment ensures the quality of natural gas and prevents downstream, including gas engines, compressors, metering stations, and purification membranes.

How does a Coalescer Filter Work?

A coalescer filter is a filtration system that consists of many walls or screens. A fluid is separated such as a gas-water mixture using various components by capturing multiple sections. Hence, the elements can be recovered in their pure form while the contaminants are drained away for disposal and purification.

In gas-water separation, the gas stream carrying water droplets is transferred into the coalescer inlet, which diffuses via the filter component and exits through an outlet port or dehydrated gas.

Key Features of Fuel Gas Coalescer
  • Removes aerosols of 0.3 microns and above at 99.9 percent efficiency
  • Strictly adhere to industry standards and codes
  • Possess either manual or automatic drainage
  • Support high flow capacity and system pressure
  • Convenient access to components through quick opening enclosures
What Type of Industries Require Fuel Gas Coalescer Filter?

You can use this industrial device for different applications that require clean and dry fuel gas. It protects engines, gas turbines, compressors, burners and turbo equipment. It is used in the following industries:

  • Mining
  • Oil and gas
  • Processing of natural gas
  • Power generation
  • Petrochemical
Why Install Fuel Gas Coalescer?

This device has become an absolute necessity for all applications where clean and dry gas is required for the gas-powered production process. The contaminants in the fuel gas can result in financial consequences if not removed timely. Particularly, liquid contaminants can block the supply lines and bring the production to a stop.

  • Efficient removal of contaminants
  • Reduce downtime
  • Extend the service life of vital components
  • Small footprint and compact design
  • High-efficiency separation through coalescence techniques

Fuel Gas Coalescers


High-quality coalescing devices ensure the effective removal of contaminants at desired micron size and efficiency. It offers comprehensive gas fuel that offers maximum energy for smooth system operation and performance.

When choosing a fuel gas coalescing filter, you should consider a few factors, including operating temperature/pressure, a flow rate of the system, type and design of the component, characteristics of contaminants in the gas, and overall configuration.
