Abstract: The invention relates to a method for producing 1,2-dichloroethane, wherein a) ethene, hydrogen chloride, and oxygen are fed into an oxychloridation reactor and converted to a product gas flow containing 1,2-dicloroethane, non-converted ethene, and carbon dioxide, b) 1,2-dichloroethane is separated from the product gas flow, an exhaust gas containing ethene remaining, c) the exhaust is consumed at least partially in that it is returned to the oxychloridation reactor and/or fed into a chemical conversion consuming ethene, particularly a direct chloridization, whereupon d) the product gas flow and/or the exhaust gas is brought into contact with a fluid absorptive material for removing carbon dioxide, said material comprising at least one amine, an amino carbolic acid, an amino carbolic acid salt, an amino sulfonic acid, an amino sulfonic acid salt, or a mixture thereof. The method allows the efficient use of the utilized ethene.

Abstract: The present invention relates to an apparatus for the tangential introduction of a gas-loaded liquid stream into the top of a column in which gas and liquid are separated. Entry into the column top proceeds through a conventional radially arranged port, to which, however, a special tube construction connects which ensures as smooth as possible non-turbulent flow and its tangential exit into the column top.

Abstract: The invention relates to an absorbent, comprising an aqueous solution (A) of at least one amino acid salt of the formula (I), wherein R1 and R2 independently from each other represent alkyl or hydroxyalkyl, R is hydrogen, alkyl or hydroxyalkyl, or a group R together with R1 is alkylene, M is an alkali metal, and n an integer from 1 to 6, and (B) of at least one primary alkanolamine, which is substantially free of inorganic alkaline salts. The absorbent is used in a method for removing carbon dioxide from a gas flow, particularly combustion exhaust gases. Preferred amino acid salts (A) are N,N-dimethylamino acetic acid potassium salt, N,N-diethylamino acetic acid potassium salt and N-ethyl-N-methylamino acetic acid-potassium salt. Preferred alkanolamines (B) are 2-aminoethanol, 3-aminopropanol, 4-aminobutanol, 2-aminobutanol, 5-aminopentanol, 2-aminopentanol and 2-(2-aminoethoxy)ethanol.
