Zusammenfassung:	"IMPROVED SEPARATION OF ETHANE AND HIGHER HYDROCARBONS FROM NATURAL GAS" Ethane and higher hydrocarbons are separated by rectification from natural gas under elevated pressure. To obtain higher ethane yields, even for gases poor in ethane, an open mixture cycle with multistage fractional condensation is employed for the production of cold. One part of the thus-obtained condensates are introduced into the rectifying column to obtain the C2+ hydrocarbons and the other part is recirculated to provide the required cold.
