Abstract

The invention provides a process for the separation of a contaminant or mixture of contaminants from a CH4-comprising gaseous feed streem, comprising the subsequent steps of: a) passing a CH4-comprising gaseous feed streem comprising the contaminant or the mixture of contaminants in to and through a cold porous body having a temperature below the sublimation temperature of the contaminant or mixture of contaminants and contacting the CH4-comprising gaseous feed streem at elevated pressure with the surface of the cold porous body to obtain a porous body comprising solid contaminant or mixture of contaminants and a contaminant-depleted product gas; and b) reducing the pressure to obtain fluid contaminant or mixture of contaminants and a cold porous body. c) removing the fluid contaminant or mixture of contaminants, wherein the contaminant is selected from CO2, hydrogen sulphide, mercaptans, siloxanes and carbonyl sulphide, or a mixture thereof.
