摘要

A process and apparatus for separating at least part of a gaseous product from a feed stream which comprises contaminants. The process comprises: 1) providing the feed stream; 2) cooling the feed stream to a temperature at which a slurry stream is formed which comprises solid contaminant, liquid phase contaminant and the gaseous product; 3) introducing the slurry stream as obtained in step 2) via a plurality of tangentially directed inlet means into an upper part of a separation device, thereby creating a swirl of the slurry stream which allows at least part of the gaseous product to flow upwardly and solid contaminant and liquid phase contaminant to flow downwardly; 4) removing at least part of the gaseous product from the upper part of the device; and 5) removing a stream comprising liquid phase contaminant from a lower part of the device.
