Fuel Gas Conditioning Applications

Fuel gas conditioning for power equipment such as gas engines and gas turbines can be addressed by Air Liquide Advanced Separations' (ALaS) PEEK-Sep membrane systems. The heating value of the gas is adjusted to the target specification by removing C2 + hydrocarbons. In some cases, PEEK-Sep membranes are used to increase the heating value of the gas by removing an excessive amount of carbon dioxide or nitrogen. ALaS' flexible process design addresses diverse customer needs for fuel gas conditioning that improves engine performance, reduces maintenance and increases uptime.

An example of heavy hydrocarbon removal from pipeline gas is shown in the figure below. If the operation of gas driven power equipment is affected by heavy hydrocarbons in the pipeline gas, upgrading of the gas, utilizing the PEEK-Sep membrane system allows improved operation with no loss of hydrocarbon values. A compact membrane skid is the only add on equipment required.
