摘要： The disclosure includes a process for treating a natural gas containing carbon dioxide wherein the natural gas is separated by a cryogenic process in order to provide, on the one hand, a stream of liquid carbon dioxide, containing hydrocarbons, and, on the other hand, purified natural gas; at least one part of the natural gas is cooled in a first heat exchanger and then in a second heat exchanger before the cryogenic process and/or before a reflux to the cryogenic process; at least one part of the stream of liquid carbon dioxide is recovered in order to provide a stream of recycled carbon dioxide; the stream of recycled carbon dioxide is divided into a first portion and a second portion; the first portion is expanded and then heated in the first heat exchanger, in order to provide a first stream of heated carbon dioxide; the second portion is cooled, then at least one part of the second portion is expanded and then heated in the second heat exchanger, in order to provide a second stream of heated carbon dioxide; at least some of the hydrocarbons contained in the first stream of heated carbon dioxide and in the second stream of heated carbon dioxide are recovered by liquid/gas separation.

摘要： The method allows pretreatment of an acid gas that can comprise more than 10% H2S, for example a natural gas or a gas associated with the production of a crude petroleum effluent. The gas is dehydrated in unit DH, then cooled by heat exchangers E9 to E12 and by expansion carried out through valve V7. Cooling allows part of the H2S contained in the gas to be condensed. The condensates are separated from the gas in drum B1. The liquid recovered at the bottom of drum B1 is pumped and injected into well P to be sequestered in an underground reservoir or a geologic structure. The gas discharged at the top of drum B1 is depleted in H2S. This gas is sent through line 43 to a treating site in order to be subjected to additional treatments prior to being used.
