Abstract
For the separation of ethane and higher hydrocarbons from a high pressure incoming gas containing hydrocarbons, the raw gas is cooled and expanded in several stages and the condensates that are produced are fed to a rectifying column to provide an overhead gaseous product essentially consisting of methane and a bottoms product consisting essentially of ethane and higher hydrocarbons. To save energy, the raw gas and/or the product streams are heat exchanged in parallel streams under different pressures, the cooled high-pressure gas is work-expanded and the condensates produced by cooling and expansion are fed separately to the rectifying column.
