Abstract: The invention relates to a method for removing COS from a stream of hydrocarbon fluid containing COS, in particular, from a stream of gas, such as for example, natural gas, synthesis gas from heavy oil or heavy residues or refinery gas, or from liquid or liquefied hydrocarbons, such as for example, LPG (Liquefied Petroleum Gas) or NGL (Natural Gas Liquids) and to a wash liquid for use in methods of this type. The stream of fluid is brought into direct contact with the inventive wash fluid in an absorption or extraction zone. Said wash fluid consists of an aqueous amine solution which contains 1.5 to 5 moles/l of an aliphatic alkanolamine having between 2 and 12 C atoms and 0.4 to 1.7 moles/l of a primary or secondary amine as the activator. Substantially all of the COS is removed from the stream of fluid using the inventive amine wash. The stream of fluid which has been substantially cleaned of COS and the wash fluid which is loaded with COS are subsequently separated from one another and both fluids are fed out of the absorption or extraction zone. The wash fluid can subsequently be regenerated in the known manner and can be fed back to the absorption or extraction zone.

Abstract: A process for removing impurities from 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone (I), which comprises initially preparing the 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone containing the undesirable impurities in a manner known per se by acetylating 3-(2'-hydroxylethyl)-dihydro-2(3H)-furanone, subsequently treating it with strong mineral acids and finally removing the decomposition products of the undesirable impurities from I.

Abstract: The disclosure concerns a process for removing mercaptans from fluid streams comprising same, especially from hydrocarbon gas streams, for example natural gas, synthesis gas from heavy oil or heavy residues or refinery gas, or else from liquid hydrocarbons, for example LPG (liquefied petroleum gas). The invention comprises intimately contacting the fluid stream in an absorption or extraction zone with a scrubbing liquor comprising at least one aliphatic alkanolamine of 2-12 carbon atoms, the amount of wash liquor being supplied to the absorption or extraction zone being sufficient to remove at least CO2 and H2S essentially completely from the fluid stream, and separating the substantially decontaminated fluid stream and the contaminated wash liquor and discharging them from the absorption zone. The substantially complete removal of CO2 and H2S is accompanied by the removal from the gas, stream of a very large portion of the mercaptans as well, without a significant fraction of the hydrocarbon gases dissolving in the wash liquor.

Abstract: A description is given of an absorption medium for removing carbon dioxide from a gas stream, which comprises an aqueous solution of at least one amine and at least one aminocarboxylic acid and/or aminosulfonic acid. The concomitant use of an aminocarboxylic acid or aminosulfonic acid reduces the energy required for regeneration of the absorption medium.
