Abstract: A method for removing high-boiling hydrocarbons from water-soluble solvent flows, wherein said solvent flows are produced in industrial processes which circulate a solvent as a part of the process, and the solvent must be periodically or permanently freed of high-boiling hydrocarbons which influence the quality or the desired properties of the solvent in an unwanted way, and water is added for carrying out the method in a phase separator, so that the high-boiling hydrocarbons are separated off because of their immiscibility with water, and then the water-miscible phase containing water and solvent is returned to the process. According to the invention, the proportion of high-boiling hydrocarbons in circulating solvents in an industrial process can be kept permanently low.

Abstract: The invention relates to a method and apparatus for reducing nitrosamines, formed in removal of CO2 from off-gases by means of an aqueous amine solution. A substream of the aqueous amine solution, loaded with nitrosamines, is branched off from a washing fluid circulation and is concentrated by evaporating water and low-boiling constituents. The concentrated amine solution is retained at the boiling point in a unit in which a liquid phase and a vapor phase are in contact to establish a vapor/fluid equilibrium between the phases. The vapor phase is irradiated with UV light, which decomposes nitrosamines entering the vapor phase. Following decomposition of nitrosamines, the concentrated amine solution is recycled to the washing fluid circulation for further use in the scrubber.

Abstract: A methane-rich gas from synthesis gas is made in a methane reactor with a row of methanation stages and, at an upstream end of the row of methanation stages, a CO conversion stage. An incoming stream of synthesis gas containing CO and H2 is split into a plurality of partial streams, one of which is fed to the reactor upstream of the CO conversion stage. Each of the other partial syngas streams is fed to the reactor upstream of a respective one of the methanation stages such that methanation takes place in each of the methanation stages and gas exits from the stages and mixes with the partial syngas stream being fed to the next downstream stage. A plurality of partial streams are diverted from a product-gas stream issuing from the furthest downstream stage and are each fed to the reactor upstream of a respective one of the methanation stages.
