Abstract (en)

[origin: CA3103733A1] The invention relates to a device (100) for desulfurizing natural gas, comprising a desulfurization system (102) for sour gas (101), which together with the desulfurized natural gas (103) forms a hydrogen sulfide-containing acid gas (104); a system (106) for obtaining elemental sulfur (107) and a hydrogen sulfide-containing tail gas (108) as exhaust gas from the acid gas (104) of the desulfurization system (102); a device (1) for generating a flow and gypsum from the tail gas (108) or the acid gas (104) or from a mixture of the acid gas (104) and the tail gas (108); and a gas line system (105) for supplying acid gas (104) from the desulfurization system (102) to the system (106) for obtaining elemental sulfur (107) and to the device (1) for generating the flow (24) and gypsum (21) and for supplying tail gas (108) from the system (106) for obtaining elemental sulfur (107) to the device (1) for generating the flow (24) and gypsum (21). The gas line system (105) has a gas distributing device (109) which supplies acid gas solely to the system (106) for obtaining elemental sulfur (107) in a first position and solely to the device (1) for generating the flow (24) and gypsum (21) in a second position and which supplies a first part of the acid gas (104) to the system (106) for obtaining elemental sulfur (107) and a second part of the acid gas (104) to the device (1) for generating the flow (24) and gypsum (21) in a distributing position. The invention additionally relates to a method for desulfurizing natural gas using such a device.
