These units are designed to protect natural gas fueled engines and turbines from liquid slugs, solids (< 0.1 microns) and liquid aerosols. Additionally, the fuel gas is superheated above the hydrocarbon and water dew points to prevent liquid condensation in the turbine’s combustion chambers.
The preheating shall be done with a tailored super-heaters, TEMA Shell & Tube Exchangers or electrical process heater.
Basing on the turbine technical features PF shall customize the required final filtration stage (usually done with coalescing cartridge / vane pack). The filtration shall assures the NG quality specifications providing dry, clean fuel to increase the life and reliability of the downstream equipment.
