 In the Oil and Gas, Petrochemical and Oil Refining industries, Liquid-Gas coalescers are widely used to remove water and hydrocarbon liquids to <0.011 ppmw (plus particulate matter to <0.3 um in size) from natural gas to ensure natural gas quality and protect downstream equipment such as compressors, gas turbines, amine or glycol absorbers, molecular sieves, PSA's, metering stations, mercury guard beds, gas fired heaters or furnaces, heat exchangers or gas-gas purification membranes.In the Natural Gas industry, gas/liquid coalescers are used for recovery of lube oil downstream of a compressor.All liquids will be removed but lube oil recovery is the primary reason for installing a coalescer on the outlet of a compressor.
