As natural gas flows through a pipeline, it loses pressure due to friction against the inside or the pipe. The gas needs pressure to continue moving. Compressor booster stations located along the pipelines keep the pressure high enough to allow the gas to flow. Additionally, these lines are subject to periodic pigging (cleaning) processes which can dislodge solid and liquid contaminants that have accumulated over time.
Natural gas traveling the length of a pipeline can pick up contaminants such as pipe scale, compressor lube oilm water and chemicals used to reduce pipe corrosion, causing:
Sending the natural gas through Parker's 10C or 100WS media prior to entering the compressor station will eliminate any solids and liquids that would otherwise contribute to compressor failure. A coalescing filter should be used after compression to eliminate compressor lube oil prior to the gas being introduced back into the pipeline.
