In a method of recovering carbon dioxide from a gaseous mixture of carbon dioxide and dimethylsulphide, the gaseous mixture is contacted with liquid carbon dioxide. The dimethylsulphide is condensed out of the mixture of gaseous carbon dioxide and dimethylsulphide when the mixture contacts liquid carbon dioxide to form a solution of dimethylsulphide in liquid carbon dioxide and effectively scrub the gaseous carbon dioxide free of dimethylsulphide. The preferred apparatus comprises an enclosed distillation column (2) filled with a high efficiency structural packing material (3). The gas mixture is arranged to pass upwardly through the distillation column (2) while liquid carbon dioxide from a liquid carbon dioxide supply (7) is arranged to flow downwardly through the distillation column (2). <IMAGE> |
