    Abstract: A process is disclosed for the purification of a gaseous stream contaminated at least with CO.sub.2 and H.sub.2 S. The gaseous stream is preheated and subjected, in the presence of recycled SO.sub.2, to a catalytic conversion of H.sub.2 S into elemental sulfur. The thus-obtained sulfur is separated, and the residual gas, which contains at least H.sub.2 S, SO.sub.2, CO.sub.2, and water, is freed absorptively from SO.sub.2 after oxidative conversion of H.sub.2 S to SO.sub.2. It is proposed that the residual gas, after oxidative conversion of H.sub.2 S to SO.sub.2, is cooled in heat exchangers, preferably regenerators, and is subsequently scrubbed with a solvent consisting predominantly of tetraethylene glycol dimethyl ether.

    Abstract: For conducting exothermic catalytic reactions, e.g., production of methane from CO.sub.x and H.sub.2, a reactor is cooled internally by indirect heat exchange with a single heat exchanger provided in the reactor feed inlet region with a gradually increasing surface intensity (defined as the product of the overall coefficient of thermal conductivity, (h), of the tube wall times the cooling surface density, m.sup.2 /m.sup.3) reaching a maximum intensity at a central zone of the heat exchanger where the preponderant cooling occurs. A zone of gradually decreasing cooling surface intensity may also be provided at the outlet end of the reactor, and uncooled adiabatic zones may be incorporated in the zones immediate the inlet and outlet ends of the reactor.

    Abstract: In a sulfur condenser and degasser system associated with a Claus furnace, the condenser comprises a wound cross-countercurrent heat exchanger. Liquid sulfur is passed into the top of the condenser as reflux so that ascending sulfur droplets can be coalesced and the condenser can act as a rectifying column. The degassing is preferably carried out substantially simultaneously with the formation of liquid sulfur.

    Abstract: This invention is a method for the recovery of elemental sulfur from a gas mixture containing H.sub.2 S. The gas mixture is first subjected to desulfurization in a Claus installation which has a thermal part and a catalytic part resulting in the recovery of elemental sulfur. Sulfur compounds still contained in the Claus tail gas are then transformed into H.sub.2 S by means of hydrogenation and, if necessary, by means of hydrolysis and the hydrogenated Claus tail gas is subjected to catalytic direct oxidation of the H.sub.2 S to elemental sulfur. The Claus installation comprises exactly one catalytic stage and the catalytic direct oxidation also takes place in exactly one reactor. Sulfur recovery rates of 99.3% to 99.6% are achieved by the method of the invention.

    Abstract: The invention relates to a process for the desulfurization of a crude gas stream containing at least H.sub.2 S in a Claus plant, afterburning of Claus waste gas, and gas washing of the waste gas from the afterburning to remove SO.sub.2, in which SO.sub.2 recovered by the gas washing is recycled to a point before the Claus plant. According to the invention, within the Claus plant, between 60% and 90%, preferably between 67% and 85%, and especially preferably between 67% and 80% of the sulfur contained in the crude gas is separated directly from the crude gas, and between 33% and 10%, preferably between 25% and 10%, and especially preferably between 20% and 15% of the sulfur originally contained in the crude gas is recycled as SO.sub.2. The gas washing to remove SO.sub.2 is advantageously carried out with an absorbing agent having a physical action. A partial stream of the crude gas can be conveyed directly into the afterburning, bypassing the Claus plant. In addition to a Claus reactor operated at a temperature of between 850.degree. and 1300.degree. C., preferably between 900.degree. and 1100.degree. C., the Claus plant can contain one or more catalytic and/or thermal reactors for sulfur production and condensers for sulfur recovery, use only thermal stages for sulfur production, or consist of a direct-oxidation Claus plant.

    Abstract: For the removal of sulfur compounds, especially H.sub.2 S, from gases that contain hydrocarbons, and/or CO.sub.2, the gases are scrubbed with a physical solvent, which is to be regenerated and reused. To obtain sulfur free of hydrocarbons, as well as a practically sulfur-free LPG fraction and optionally a C.sub.5+ fraction, an oxidizing agent is added to the solvent for reacting the sulfur compounds to elemental sulfur, and the sulfur is separated. The concomitantly absorbed hydrocarbons and/or CO.sub.2 can then be desorbed from the separated solvent by physical regeneration and can be recovered.
