    Abstract: A process for the removal of CO2 and/or H2S from gases containing olefins and acetylenes by absorption in an aqueous solution of an alkali metal salt of amino acid and desorption by decompressing and heating the solvent, which comprises treating the solvent, before or after desorption, with a hydrocarbon mixture substantially consisting of benzene for the purpose of removing impurities and, after said treatment, separating the hydrocarbon mixture from the aqueous solution.

    Abstract: A process for the thermal decoking of cracked gas coolers for the indirect cooling, by means of water, of ethylene-containing cracked gases which are obtained by thermal cracking of hydrocarbons in the presence of steam in an indirectly heated tube cracking furnace, at cracked gas exit temperature of above 750 DEG C., in which, instead of a heated steam/air mixture, heated air, without steam, is passed through the cracked gas cooled tubes which are to be decoked.

    Abstract: 1,142,339. Removing CoS from light hydrocarbons. BADISCHE ANILIN- & SODAFABRIK A.G. 17 June, 1966 [19 June, 1965], No. 27166/66. Heading C5E. Carbon oxysulphide is removed from mixtures of liquid C 3 -hydrocarbons, such as are obtained by cracking gaseous and/or liquid hydrocarbons, by passing the mixture in the liquid phase over a substance containing at least one of the oxides of cadmium, zinc, nickel or cobalt deposited on or mixed with a carrier of large specific internal surface area such as silica gel, active alumina, pumice or magnesium silicate to give a porous composition. The preferred substance has pores of diameter 50-150 Š and contains 10-70% by weight oxide, particularly 30-60% cadmium oxide. The carrier may be loaded by treatment with a saturated aqueous solution of a readily decomposable metal salt e.g. an acetate and heating in air below 400‹ C., or the oxide and carrier may be mixed, pressmoulded and if desired, roasted. The purification may be effected at 10-45 atmos. and 20-60‹ C. to reduce the CoS content of, for example, C 3 mixtures containing propyne or propadiene to less than 1 p.p.m.

    Abstract: A process for the thermal decoking of cracked gas coolers for the indirect cooling, by means of water, of ethylene-containing cracked gases which are obtained by thermal cracking of hydrocarbons in the presence of steam in an indirectly heated tube cracking furnace, at cracked gas exit temperatures of above 750.degree.C, in which air or an air/ oxygen mixture in heated in the tube cracking furnace to temperatures of from 600 to 1.100.degree.C and the heated air or air/oxygen mixture is passed through the cracked gas cooler tubes which are to be decoked and at the same time a steam pressure of 90 to 150 bar is maintained on the boiling water side of the cracked gas cooler.

    Abstract: A process for removing CO2 and/or H2S from a cracked gas by bringing the said gas, at from 20 to 60.degree.C and under atmospheric pressure or superatmospheric pressure, into contact, in an absorption zone, with an aqueous solution of the alkali metal salts of aminoacids as the scrubbing liquor, freeing the solution leaving the absorption zone from CO2 and/or H2S by heating in a desorption zone, if necessary after first letting down the pressure, and then recycling the so-regenerated scrubbing liquor to the absorption zone, wherein the scrubbing liquor used is an aqueous solution of an alkalimetal salt of a N-dialkyl-.alpha.-aminomonocarboxylic acid.
