METHOD AND DEVICE FOR CONTINUOUS PRODUCTION OF HYDROGEN SULPHIDE

摘要

The invention relates to a method and a device for the continuous production of hydrogen sulphide H₂S, wherein the crude gas stream containing the H₂S generated in the production contains polysulphanes (H₂Sx). The crude gas stream is passed through a catalytically active material (41) contained in a vessel (42) at a temperature of 114 to165°C and the sulphur generated is trapped in the sump (43) of the vessel (42) and recycled for production of H₂S. The device according to the invention, comprises a reactor (1) for the reaction of sulphur and hydrogen, a cooler (40), connected to the reactor (1), for cooling a crude gas stream containing H₂S withdrawn from the reactor (1) to 114 to 165°C, a vessel (42) connected to the cooler (40) and containing catalytically active material (41) with a sump (43) for trapping sulphur generated in the vessel (42) from the crude gas stream containing polysulphanes at 114 to 165°C and a line (44), connected to the sump (34) of the vessel (42) which opens out in the cooler (40) or in the reactor (1) for the recycling of sulphur.
