Abstract
Method and process plant for liquefaction of gas, particularly natural gas with multicomponent refrigerant, suited for small and medium sized scale, where the plant solely is based on conventional two-flow plate heat exchangers and conventional oil lubricated compressors. By the arrangement of the heat exchangers and the compressors according to the invention it is avoided that oil from the compressors, that to some extend will follow the flow of refrigerant, may reach the coldest parts of the plant. Any freezing of oil and plugging of conduit etc. is thus avoided.
