Definitions

  • the invention relates to a process for the production of hydrogen sulfide and sulfur dioxide-containing process gas for the Claus process from hydrogen sulfide-containing feed gas which is burned with pure oxygen at temperatures in the range of 800 to 1650 ° C by means of several burners opening into a combustion chamber, in which, respectively Pure oxygen is introduced via a central tube, the feed gas is passed through a tube surrounding the central tube coaxially, and purge gas is introduced into the combustion chamber via a ring channel coaxially surrounding the feed gas tube and via a central tube of water vapor into a support combustion chamber arranged at a distance from the burners and connected to the combustion chamber a tube surrounding the central tube coaxially fuel gas and fed via a Schugasrohr coaxially surrounding outer tube Sauerwasserstrippgas and the combustion gases formed in the Stützakiungsraum be guided into the combustion chamber.
  • DE 34 30 015 C1 discloses an apparatus for burning hydrogen containing hydrogen to produce a process gas containing hydrogen sulfide and sulfur dioxide for the Claus process, with a combustion chamber for generating the process gas at temperatures of 1000 to 1300 ° C. Feeders for air and hydrogen sulfide containing gas to the combustion chamber and with a Stützfashionung in a combustion chamber opening into the combustion chamber known, the combustion gases of the support fire are passed into the combustion chamber and the support fire supply lines for hydrocarbon-rich heating gas, water vapor and air.
  • the combustion chamber opens at least one burner having a central tube for the oxygen supply, a coaxial surrounding the central tube second tube for the supply of the hydrogen sulfide containing ga- ses and a second conduit coaxially enclosing annular channel for the supply of combustion air into the combustion chamber.
  • the processing of feed gases succeeds with highly fluctuating levels of hydrogen sulfide and highly fluctuating amounts of feed gas.
  • combustion is with pure oxygen, with air at extremely high levels of hydrogen sulphide, and with air and oxygen under normal conditions.
  • the feed gas containing hydrogen sulfide is first converted by partial combustion to a mixture of hydrogen sulfide and sulfur dioxide, aiming for a molar ratio of the two components of 2: 1.
  • the recovered gas mixture is converted in a catalytic Claus plant to elemental sulfur and water and abandoned the exhaust gas of a desulfurization.
  • the exhaust gas of the desulfurization is usually modified in a thermal afterburning to sulfur dioxide, so that an exhaust gas is produced, which, however, contains only a small amount of sulfur dioxide.
  • the oxygen required for maintaining the high temperatures in the flame area of the burner and in the combustion chamber is made available in part, so that the total demand for oxygen can be kept low.
  • the hydrogen present in the product gas mixture of the combustion chamber is valuable in the further treatment of the gas mixture, since hydrogenation reactions are possible without the addition of foreign hydrogen.
  • the gas components hydrogen and carbon monoxide can be used as synthesis gas.
  • the outer annular channel is purged with inert gas, preferably carbon dioxide, to prevent the backflow of combustion gases from the combustion chamber, so that the combustion takes place exclusively with pure O 2 (> 90%).
  • inert gas preferably carbon dioxide

Abstract

La présente invention concerne un procédé de préparation d'un gaz de processus destiné au procédé Claus et contenant de l'acide sulfhydrique et du dioxyde de soufre. En l'occurrence, dans plusieurs brûleurs débouchant dans une chambre de combustion, on fait brûler avec de l'oxygène pur un gaz de départ contenant l'acide sulfhydrique. Chacun de ces brûleurs comprend un tube central amenant l'oxygène pur dans la chambre de combustion, un tube entourant coaxialement le tube central et amenant dans la chambre de combustion le gaz de départ, et un canal annulaire entourant coaxialement le tube du gaz de départ et amenant dans la chambre de combustion un gaz inerte servant de gaz de purge. On pourra avantageusement utiliser comme gaz inerte le CO2 obtenu par désorption du méthanol chargé.
