FUEL GAS CONDITIONING: FuelSep™ (REMOVE H₂S, C₃₊, CO₂, N₂, H₂O)

Problem

Raw gas often cannot be used to fuel the gas engines or gas turbines driving pipeline compressors due to poor quality. Significant concentrations of H₂S and/or C₃₊ will cause corrosion and carbon build-up in the gas engine. CO₂ and nitrogen will lower the BTU value. Any of these impurities can compromise engine operation, increase downtime or at a minimum put emissions out of compliance. Their presence in the raw gas can even render the gas unusable as fuel so expensive diesel has to be trucked in.

Membrane Solution

MTR’s FuelSep™ systems purify raw gas sidestreams to premium quality fuel gas. MTR membranes easily remove H₂S, C₃₊, CO₂, N₂ and water from fuel gas at moderate pressure. Because these impurities are taken out of the fuel gas and returned to the compressor suction, there are no effluent streams to be disposed of. Any C₃₊ removed from the fuel gas goes back into the main gas stream, so all NGL in the raw gas stream is available for downstream recovery, if desired.

These units have no moving parts, are simple to install and operate unattended. Many units are operating worldwide.

Benefits

FuelSep^® unit operating in Texas

Removes heavy components such as C₃₊ to clean up fuel gas
