| description | The invention relates to a process for recovering methane from a gas stream comprising methane and ethylene, comprising: a sorption step which comprises contacting the gas stream comprising methane and ethylene with a sorption agent which has a lower affinity for methane than for ethylene, resulting in sorption of ethylene and part of the methane by the sorption agent and in a gas stream comprising methane; a rinse step which comprises contacting a gas stream, comprising a compound for which the sorption agent has a higher affinity than for methane, with the sorption agent containing sorbed ethylene and methane, resulting in sorption of the compound for which the sorption agent has a higher affinity than for methane by the sorption agent, in desorption of methane from the sorption agent and in a gas stream comprising methane; and a desorption step which comprises desorbing sorbed ethylene and the sorbed compound for which the sorption agent has a higher affinity than for methane resulting in a gas stream comprising ethylene and the compound for which the sorption agent has a higher affinity than for methane. |
