摘要

the object of the invention is u0151lefinek extraction procedure pru0151pilu00e9nt, hidru0151gu00e9nt, ethylene, methane, ethane, and acetilu00e9neket, diu00e9neket nehu00e9zszu00e9nhidru0151gu00e9neket containing krakkgu00e1zelegyek flow.the procedure is the following steps: (a) the above metu00e1nmentesu00edtu00e9se hu0151gy cracked gas, methane, and at least a part of the hidru0151gu00e9nnek gyaku0151rlatilag teljesmennyisu00e9gu00e9t eltu00e1vu0151lu00edtju00e1k the krakkgu00e1z flow.and ru00e9szlegesenmetu00e1nmentes gu00e1zu00e1ramu0151t is produced, (b) the above ru00e9szlegesenmetu00e1nmentesu00edtett gu00e1zu00e1ramu0151t u00e9rintkeztetik u0151lyan fu00e9msu00f3u0151ldattal, capable of selectively abszu0151rbeu00e1lni the ethylene and the pru0151pilu00e9nt,aminekeredmu00e9nyeku00e9nt gyaku0151rlatilag u0151lefinmentes du00fasu00edtu0151tt gu00e1zu00e1ramu0151t, u00e9sku00e9miailag abszu0151rbeu00e1lt u0151lefinekben rich fu0151lyadu00e9ku00e1ramu0151t receiveand (c) the extraction of the u0151lefinek referred to above abszu0151rbeu00e1lu00f3 fu00e9msu00f3u0151ldatu00e1bu00f3l chemically.the object of the invention is still proceeding from ethylene, ethane, u00e9sacetilu00e9nt containing gas phase flow of extrusion.the flow rate of the ahu0151l gyaku0151rlatilag will be free of the c3 + szu00e9nhidru0151gu00e9nektu0151l fentielju00e1ru00e1s's help.the invention is a process for vu0151natku0151zik u0151lyan, ahu0151l c4 + szu00e9nhidru0151gu00e9nektu0151l gyaku0151rlatilag free, pru0151pilu00e9nt, pru0151pu00e1nt, methyl acetilu00e9nt and pru0151padiu00e9nt containing gas streamaccording to the invention, by means of the procedure pru0151pilu00e9nt nyernekki. a
