摘要： In the process for gasification of municipal waste plastic waste material pieces of about a 20 mm piece size are compressed and heated at a pressure of from 40 to 80 bar until at a temperature of from 230.degree. to 300.degree. C. to produce an HCl-containing gas and a plastic waste material containing less than 3000 mg of HCl per kg and the HCl-containing gas produced is washed with water to produce a hydrochloric acid solution. The plastic waste material is then heated further until at a temperature of from 400.degree. to 500.degree. C. to form a plastic melt having a viscosity of less than 300 cSt, advantageously less than 50 cSt. This plastic melt is gasified at a pressure of 4 bar with oxygen in a flame reaction to form a crude gas containing a preponderant proportion of CO in relation to CO.sub.2 in a gasification chamber having a central temperature of about 1600.degree. C. The crude gas is withdrawn from the gasification reactor at a temperature of 1300.degree. to 1600.degree. C., quenched with a water spray to cool it until at a temperature of 700.degree. to 900.degree. C. and then further cooled by indirect heat transfer in a heat exchanger producing steam until at a temperature of from 220.degree. to 300.degree. C. The cooled crude gas is dedusted until a dust content of less than 20 mg/Nm.sup.3 of crude gas is reached and the dedusted gas is washed and desulfurized to form the product gas.

摘要： In a method of treating waste water obtained in a direct washing with water of raw gas in a plant for a gasification of gas, the waste water is first settled in a settling tank and a resultant concentrated slime-containing water is subjected to a multi-stage oxidation with air or oxygen only at the temperatures of between 20.degree. C., and 80.degree. C., and the slime-containing water obtained after the oxidation is conveyed to a filtration system or a slime-depositing container.

摘要： The process removes acid components including sulfur oxides and nitrogen oxides from the exhaust gases of industrial furnaces and includes oxidizing the nitrogen oxide contained in the exhaust gases with the oxygen contained in the exhaust gases at a exhaust gases temperature between 300.degree. and 900.degree. C. before entry of the gases into a first absorption stage, with an addition to the exhaust gases of an organic compound, preferably methanol, as a radical former. After oxidation of nitrogen oxides the exhaust gases undergo a two-stage absorption using aqueous ammonium salt solutions as absorption liquid, whose pH-value is continuously adjusted to less than 5 by addition of aqueous ammonia solution. The mol ratio of NO.sub.2 to SO.sub.2 in the exhaust gases introduced to the second absorption stage is maintained between 0.01 and 0.5 by diverting a portion of the exhaust gases prior to the first absorption stage to the second absorption stage. The salt solutions obtained thereby are neutralized together and evaporated, whereby the salts so produced, after pelletization or granulation represent a useful fertilizer.

摘要： A gas with a hydrogen content of at least 85 volume percent of partial oxidation crude gas is produced in a method including cooling of the gas after waste heat boiler of a gasifier by adding converted circulating gas in a quenching zone. The resulting gas mixture after corresponding gas treatment is subjected to a CO-conversion and then separated into a circulating gas partial stream and a product gas partial stream. The circulating gas partial stream is supplied back after a corresponding compression to the quenching zone, while the product gas partial stream after a so-called acid gas washing is subjected to a further gas treatment in correspondence with a desired use.

摘要： Decribed is a method of cooling partial oxidation gas exiting at a temperature between 1,000.degree. and 1,700.degree. C. from a conically converging outlet portion of a reactor vessel into a subsequent tubular cooling zone. To prevent deposition of sticky molten impurities entrained in the gas stream on the walls in the transition region between the reactor vessel and the cooling zone, the outlet portion of the reactor vessel is provided with a ring-shaped slot for injecting at an angle between 0.degree. to 90.degree. a frustoconical stream of cooling fluid. Another ring-shaped slot is provided in the cooling zone to inject at an angle between 70.degree. to 90.degree. another frustoconical stream of cooling fluid into the cooling zone.

摘要： A process is disclosed for the working up of salvage oil, in which the salvage oil is subjected to an extraction under supercritical conditions. The halogen compounds contained in the produced extract are removed by catalytic hydrogenation. The extraction residue is eliminated by deposition or thermal treatment (gasification). In the case of a thermal treatment of the extraction residue, other residues can be simultaneously converted, so that the process is performed without yield of environmentally burdensome residues or by-products. Ethane in particular and/or propane is employed as solvent for the supercritical extraction.

摘要： A method for producing steel from fine-grained iron ores includes the step of preheating and partially reducing the fine-grained iron ores in a countercurrent heat exchanger. The preheated and partially reduced fine-grained iron ores are then reduced in a fluidized bed reactor to form sponge iron. The reduction in the fluidized bed reactor is effected with exhaust gases which consist substantially of carbon monoxide and which emanate from a melting vessel in which sponge iron is melted. The fine-grained sponge iron produced in the fluidized bed reactor is separated from the reduction gases which form during the reduction in the fluidized bed reactor. The separated fine-grained sponge iron is pneumatically transported into a carbon containing melt in the melting vessel. The transported sponge iron is melted and subjected to a final reduction in the metal melt with the carbon in the metal melt and with further carbonaceous material which is pneumatically introduced into the metal melt. The melt is refined with pure oxygen. The oxygen, carbonaceous material and sponge iron are introduced into the metal melt through at least one nozzle which is disposed below the level of the metal melt surface.
