| description | Abstract The present invention relates to a process for removing carbon dioxide from synthesis gas using a hygroscopic, physical absorption medium. The process comprises the steps where the absorption medium and the synthesis gas are cooled; water is at least partially removed from the synthesis gas by condensation; carbon dioxide is removed from the cooled synthesis gas via the cooled absorption medium in a physical absorption step at elevated pressure; laden absorption medium is treated in a plurality of serially arranged flash stages, wherein co-absorbed carbon monoxide and hydrogen are removed from the laden absorption medium in at least one first flash stage, and carbon dioxide is removed from the laden absorption medium in a flash stage arranged downstream of the first flash stage. The process features a high rate of separated carbon dioxide and a pure and dry (anhydrous) carbon dioxide product. The invention further relates to a plant for performing the process. 4--- --- : --- 4~Y P 100 3 -r 16-1 - - - - 17 C-02T-2 13 26--IP0 P0 - 21 HX-04 HX-05 --- ~27--, 2 10 T-03 --- 1--- --- 14 ---_ _ __ I 0-0 HX0 4 HX011-- -II - -- - -- - -- - --- D-291 --- 6 29---30 Fig. I |
