60724-1745 ABSTRACT An improved process for removing free liquid from a hydrocarbon-rich gas stream is disclosed. Liquid is injected into the gas stream upstream of a chiller and downstream of an acid-gas removal system and any equipment that may affect the water content of the gas stream: compressors, columns, addi- tional knockout drums, heat exchangers or the like. This enhances heat and mass transfer in a manner that both minimizes the formation of small droplets and encourages the coalescence of small droplets in the chiller. As a result, small droplets which would normally pass through a knockout drum and a standard mist eliminator are increased in size, prior to their arrival at a vapor-liquid separator to larger drops which are easily removed by the vapor-liquid separator, and the mist eliminator.
