    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: The invention relates to a method for extinguishing a smouldering fire in a silo by introducing inert gas into the silo. The inert gas is introduced through a venturi-type nozzle above the stored content in the silo with a slow streaming velocity in such a way that mass ratio of the entrained surrounding gas to the incoming liquid inert gas is between 0.5 and 20. Thus a closed inert gas layer is formed above the smouldering fire.

    Abstract: A method and a device for injecting a fluid into a layer of rock or earth, such as a crude oil-containing layer of rock or earth, for example, for the tertiary crude oil production by means of a suitable line, wherein the line is introduced into the layer of rock or earth. The line consists of an inner pipe and an outer pipe. The inner pipe is provided with injection nozzles. The injection nozzles are positioned and thus ensure a pressing of the fluid into the surrounding layer of rock or earth via the openings in the outer pipe in a positioned manner. Means which allow for a selective impacting of the individual injection nozzles, are located in the interior of the inner pipe. The fluid is pressed into the surrounding layer of rock or earth in a positioned manner.

    Abstract: For the thermal conversion of hydrogen sulfide contained in a gaseous stream, the gaseous stream is introduced into a non-catalytic reactor together with sulfur dioxide obtained from a waste gas purification facility arranged downstream of the reactor. If necessary, the sulfur yield can be regulated by feeding additional fuel gas and/or reducing gas and/or process air into the reactor. The thus-produced vapor-phase sulfur is condensed out by cooling and is obtained as a product; the resultant gaseous stream extensively freed of sulfur compounds is discharged and fed into the aforesaid downstream waste gas purification facility.
