    摘要: The present invention allows low-concentration hydrogen sulfide gas, which is generated at the time of regular inspection or start-up of a production plant, to be efficiently recovered and effectively supplied to a processing plant that uses hydrogen sulfide gas. In the invention, the hydrogen sulfide gas production plant is provided with a first supply pipe (14) that supplies hydrogen sulfide gas obtained from a sulfur recovery facility (13) to a processing plant X, and a second supply pipe (16) that is branched at a predetermined point (15) in the first supply pipe (14) and supplies the hydrogen sulfide gas from the sulfur recovery facility (13) to the processing plant X. The first supply pipe (14) has a concentration meter (22) that is provided on the upstream side than the branch point (15) and measures the concentration of the hydrogen sulfide gas. The first supply pipe (14) and the second supply pipe (16) have ON/OFF valves (23), (26), respectively, that are provided on the downstream side of the branch point (15) and perform ON/OFF control of the supply to the processing plant X through the supply pipe.

    摘要: All sulfur compounds can be efficiently removed from natural gas that contains hydrogen sulfide and other sulfur compounds such as mercaptan without using physical absorption. The process comprises an absorption step of treating natural gas by means of a chemical absorption method using an amine-containing solution to mainly remove hydrogen sulfide and carbon dioxide, an adsorption step of flowing the natural gas from the absorption step through a packed bed of a molecular sieve to mainly remove mercaptan, a recovery step of recovering sulfur compounds by converting the hydrogen sulfide removed in the absorption step into sulfur by means of the Claus process, a regeneration step of desorbing the mercaptan adsorbed on the molecular sieve in the adsorption step using heated gas and a reaction step of converting the mercaptan in the regeneration exhaust gas exhausted from the regeneration step into hydrogen sulfide. The reaction step is conducted by injecting steam or water at a ratio of H 2 O/S = 1 to 5 (molar ratio) relative to the sulfur in the regeneration exhaust gas in the presence of a catalyst under the conditions of a temperature level of 250 to 400°C and a pressure level of 1 to 10 MPa.

    摘要: Process for eliminating COS and CS2 compounds contained in an industrial gas, wherein said gas containing an appropriate quantity of water vapour is contacted with a titanium oxide catalyst arranged in a high temperature reaction zone. The reaction is carried out while maintaining at specific values the ratio R between the number of water vapor moles and the number of moles of the compound(s) COS and CS2 in the supplied gas in contact with the catalyst, as well as the temperature at the outlet from the reaction zone. The process is applicable to the treatment of industrial gases usable in organic synthesis and containing COS and CS2 as impurities susceptible of perturbating synthesis reactions.
