摘要： A process for removing impurities, in particular oxides of sulphur (SOx) and/or oxides of nitrogen (NOx) from oxygen-containing gas streams by scrubbing with at least one washing agent is described. In order to achieve effective gas purification in an economical manner even in the case of so-called large “oxyfuel” furnaces which operate with oxygen as fuel gas, it is proposed to convert the impurities at an elevated pressure of at least 2 bar with at least one basic constituent of the washing agent into salts and to wash out said impurities as dissolved salts.

NO is reacted with ammonia and oxygen to form ammonium nitrite in an NO elimination step which proceeds at elevated pressure. Likewise, the invention also relates a plant for operating the method according to the invention.

摘要： For recovering acetylene from hydrocarbons, the hydrocarbons are thermally cracked in the presence of CO.sub.2 as a diluent gas. Suitable for thermal cracking for acetylene generation is a ratio, by weight, of CO.sub.2 to hydrocarbon, of between 3:1 and 1:3, and preferably between 2:1 and 1:2. It is preferred for the CO.sub.2 to be mixed with the hydrocarbons before thermal cracking which is thereafter conducted at average reaction temperatures of between 800.degree. and 1200.degree. C., preferably between 900.degree. and 1100.degree. C. An average residence time of between 5 and 500 milliseconds (ms) of the hydrocarbons during thermal cracking has proven to be effective. As the hydrocarbon feedstock for the thermal cracking, basically C.sub.2+ alkanes, especially ethane, propane and/or butane, can be used advantageously. After the cracked gas is cooled, higher alkynes are removed from the cracked gas, then the acetylene is separated preferably by scrubbing with an absorption agent selective for acetylene. Recycle streams of hydrocarbons and/or CO.sub.2 for the thermal cracking can contribute to savings and more efficient use of the feedstock.
