    摘要： A method for reducing the loss of solvent during carbon dioxide capture from flue gas in an amine based solvent process by the steps of feeding a flue gas containing carbon dioxide to an absorber column containing an amine solvent; absorbing carbon dioxide in the amine solvent forming a rich solvent; feeding the rich solvent to at least one inter-stage cooler; recovering the rich solvent and feeding the rich solvent to a regeneration column; separating the carbon dioxide from the rich solvent and recovering the carbon dioxide to form a lean solvent; feeding the lean solvent to the absorber column. The improvement is realized by one of feeding steam to the flue gas; feeding steam to the absorber column after introduction of amine solvent; feeding the flue gas stream to a demister before feeding to the absorber column or increasing the lean solvent inlet temperature into the absorber column.

    摘要： A process for the preparation of hydrocarbon products comprising the steps of a) providing a synthesis gas comprising hydrogen, carbon monoxide and carbon dioxide; (b) reacting at least part of the synthesis gas to an oxygenate mixture comprising methanol and dimethyl ether in presence of one or more catalysts which together catalyse a reaction of hydrogen and carbon monoxide to oxygenates at a pressure of at least 3 MPa; (c) withdrawing from step (b) a reaction mixture comprising amounts of methanol, dimethyl ether, carbon dioxide and water together with unreacted synthesis gas and cooling the reaction mixture to obtain a liquid phase with the amounts of methanol, dimethyl ether and water and simultaneously dissolving carbon dioxide in the liquid phase; (d) separating the carbon dioxide containing liquid phase from a remaining gaseous phase comprising hydrogen and carbon monoxide; (e) evaporating and reacting the liquid phase being withdrawn from step (d) in presence of a catalyst being active in the conversion of oxygenates to higher hydrocarbons and a tail gas comprising carbon dioxide; (f) separating tail gas from a liquid phase with the higher hydrocarbons; and wherein pressure employed in step (c) to step (f) is substantially the same as employed in step (b).
