摘要： In a process for the production of carbon dioxide and hydrogen from a gas flow comprising at least hydrogen, at least one sulfur-comprising component and carbon dioxide originating from a Claus unit fed with a gas comprising at least 50 mol % of oxygen, the gas flow is compressed and dried in order to produce a compressed and dried gas flow and the compressed and dried gas flow is separated at a subambient temperature in order to produce at least a fluid enriched in carbon dioxide with respect to the compressed and dried gas flow and at least a fluid enriched in hydrogen with respect to the compressed and dried gas flow.

摘要： In a method for supplying nitrogen to a combustion chamber, gaseous nitrogen (9) is drawn off from an air separation unit (7) at a first pressure, the nitrogen is compressed in at least two stages (C1, C2) of a nitrogen compressor and sent to a combustion chamber (25) at a second pressure, which is the output pressure of the last stage (C3) of the nitrogen compressor, between two stages of the nitrogen compressor the nitrogen is humidified by direct contact in passing through a contactor (17) supplied at its top with water, and the humidified nitrogen is compressed in at least one stage of the nitrogen compressor and sent to the combustion chamber.

摘要： The invention relates to a method for treating a hydrocarbon feed gas stream containing CO2 and H2S to recover a purified CO2 gas stream (vii), comprising: a. Separating said feed gas stream into a sweetened gas stream (i), and an acid gas stream (ii); b. Introducing stream (ii) into a Claus unit wherein an oxygen-rich stream is used as a combustive agent in the Claus furnace, thereby recovering a liquid stream of elemental sulfur (iii) and a tail gas stream (iv); c. Introducing the stream (iv) into a Tail Gas Treatment Unit (TGTU) thereby separating said tail gas stream into a CO2 enriched gas stream (v), and a stream enriched in sulfur compounds (vi); d. Compressing stream (v) exiting the TGTU; e. Passing the compressed CO2 enriched gas through a CO2 purification unit thereby recovering a purified CO2 gas stream (vii), and the device for carrying out said method.
