Fuel gas treatment skids are used for the treatment of raw production gas. Fuel gas conditioning skids are developed to provide clean, treated gas that is essential for gas-driven types of machinery such as turbine and generator.
The gas after treatment can also be used for other purposes such as utility gas, blanketing gas or seal gas. Fuel gas treatment systems are commonly referred to as fuel gas conditioning systems, fuel gas treatment packages or fuel gas filtration and heating packages.
If generated gas is not adequately treated before supplying into the combustion chamber of gas driven generators, it can lead to significant damage to the whole machinery. Even tiny amounts of liquids, solids or over-pressurized gas entering the combustion chamber can have a deleterious impact.
Fuel gas conditioning systems are designed to shield gas-fueled engines and turbines from over-pressure, liquids, solids, and aerosols. Moreover, heating the gas correctly above the dew point of water and hydrocarbons prevents liquid condensation in the combustion chambers.

Fuel gas conditioning systems are designed to shield gas-fueled engines and turbines from over-pressure, liquids, solids, and aerosols. Moreover, heating the gas correctly above the dew point of water and hydrocarbons prevents liquid condensation in the combustion chambers.
Fuel gas treatment systems are designed to adjust the following parameters:
- The temperature of the gas
- Gas pressure
- Removal of solid impurities (dust and particles)
- Removal of liquid and condensed vapors.
The reduction of gas pressure, its filtration and scrubbing along with the cooling or heating of the gas helps in ensuring that only dry and clean gas is supplied into the combustion chamber.
Design & Functioning
The design of a fuel gas conditioning system involves a scrubber vessel or knock-out drum, coalescing filters, gas heaters, valves for pressure reduction, flow meters, and operations & emergency valves typically.

The system is mostly installed downstream to the header of the productions with a glycol contactor or separator for conditioning. Fuel gas systems can be installed with coolers or heaters depending on the conditions of the feed gas inlet.
Pressure control valves are also connected to adjust the pressure of the production gas as per the level required by the system. This leads to an adiabatic cooling effect which can lead to the formation of condensates.
The liquids and condensates that enter into the gas are scrubbed out to prevent carry-over of any fluid into the equipment downstream. The gas is then directed to the filter-coalesce units to additionally remove any solid particles or liquid carry-over. In a few scenarios, pre-heating is needed before the gas is let down.
In the final stage of the process, the gas can be superheated to ensure temperatures remain above the dew point in the downstream till it's ready for delivery to the consumer.
