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
- a device for carrying out the method, is particularly suitable in which the burners are mounted on a circle or circles surrounding the supporting firing space.
- the axially extending central tube (11) of the support (4) is supplied via line (12) steam and the between this central tube (11) and this coaxial enclosing tube (13) existing annulus heating gas. Via line (14), the ignition flame (15) is supplied with fuel gas.
- the components are not provided with reference numbers in the second burner.
- the pipes (7) coaxially surrounding annular channels (9) are given a total of 137 kmol / h of carbon dioxide.
- At the outlet of the combustion chamber (2) occur 1118 kmol / h of gas at a temperature of 904 ° C at a pressure of 1, 58 bar [a] from.
- the gas has the following composition:
