    Abstract: 1,174,278. Acetylene. BADISCHE ANILIN- & SODA-FABRIK A.G. 21 April, 1967 [22 April, 1966], No. 18429/67. Heading C5E. Acetylene is produced by incomplete combustion of gaseous or vaporized hydrocarbons (e.g. light naphtha) with oxygen, with subsequent quenching, the reaction being carried out in the presence of CO 2 which is added continuously to the hydrocarbon feed, the oxygen or the mixture thereof prior to the reaction in an amount of 10-50 vol. per cent with reference to the oxygen amount. Carbon black formation is reduced and acetylene yield increased.

    Abstract: CO2 and/or H2S are removed from gases which contain CO2 and/or H2S by means of an aqueous absorption liquid containing an alkanolamine, by a process wherein the said gas is treated, in an absorption stage, at from 40 DEG to 100 DEG C., with an aqueous absorption liquid containing from 20 to 70% by weight of methyldiethanolamine, the treated gas is taken off at the top of the absorption stage, the aqueous absorption liquid laden with CO2 and/or H2S is taken off at the bottom of this stage and is regenerated by being let down in two or more flash stages, and the final flash stage is operated under reduced pressure and the regenerated absorption liquid is recycled to the absorption stage.

    Abstract: A process for removing condensable aliphatic hydrocarbons and acidic gases such as H2S, CO2 and COS from natural gas containing these, wherein the natural gas is initially treated with polyethylene glycol dialkyl ethers, as the solvent, in a first absorption stage to effect absorption of the condensable aliphatic hydrocarbons; the natural gas drawn off from the first absorption stage is then treated with polyethylene glycol dialkyl ethers, as the solvent, under superatmospheric pressure in a second absorption stage, the acidic gases being completely or partly absorbed; the solvent charged with the condensable aliphatic hydrocarbons which is obtained from the first absorption stage is treated with water in an extraction stage, to form a hydrocarbon phase containing the condensable aliphatic hydrocarbons and an aqueous dialkyl ether phase, and the hydrocarbon phase is separated from the aqueous dialkyl ether phase. The solvent charged with acid gases which is obtained from the second absorption stage is regenerated by expansion and/or stripping in a regeneration stage and the regenerated solvent is recycled to the absorption.

    Abstract: 1. A process for removing CO2 and/or H2 S from a gas containing CO2 and/or H2 S by washing the gas with an aqueous alkanolamine-containing absorption liquid and subsequently regenerating the latter, wherein the aqueous absorption liquid used contains from 3 to 60% by weight of methyldiethanolamine and from 1 to 50% by weight of monoethanolamine, processes with two absorption stages arranged in series, in which regeneration of the laden absorption liquid is carried out using two flash stages and a stripping zone, to the extent they utilize an absorption liquid containing from 0.05 to 1 mole of monoethanolamine per litre, being excluded.
