Nkọwa Ọrụ

·MDEA Nkọwa Sistemu Decarbonization:

Apara gasị na-etedụghị site na separator ọ bụla ma na-abịa n'akụkụ ebe osisi abanyela, ebe ọ na-enwe ya anya na mfe MDEA na-azukwu site n'elu na onye isi iko aka. CO₂ na H₂S na-enweta ya karịa. A na-adaba mfe ọcha ahụ na tanki flash maka ịwụsa hydrocarbons, ikpuchi ya na exchanger mfe ọcha, ọzọ, mgbe ahụ na-abịa n'elu towerị regeneration. Na mpụga iji steam na reboiler, CO₂ na H₂S na-edozi. A na-etinye mfe ọcha ahụ gbasara ya, mechaa ya, ma na-achị ya laguuru maka ịkwado ya. Gasị acid dị n'elu towerị nwere ike iche na sulfur recovery ma ọ bụ na ngwaahịa CO₂ liquefaction.

·Ndoro-ndoto Ose Osisi + Nkọwa nke Ndoro-ndoto (TSA):

N'kà egwuregwu na-egbu agwa, ihe omimi na-adị ya n'ime exchanger mmiri akpụkpọ maka precooling, na-enyere aka ikpuchi oke C₅+ hydrocarbons. Ezi uwe ha mgbe ahụ dị elu site na turbo-expander ma ọ bụ refrigerant zuru ezu, kama oil phase (irecovery LPG/NGL) na-adịghị n'ime separator mmiri elu. Hydrocarbons elu ole na-adị n'ime gas phase baa n'ime TSA molecular sieve adsorption tower, ebe hydrocarbons elu na-adị njikọrịta. Outlet gas, na ngwaahịa hydrocarbon elu ≤ 20 mg/Nm³, enwetakwara ya n'ime liquefaction unit. Mgbe adsorption na-eche echensu, purified gas na-edunruru enweghị ike ịbawanye ya n'aka ọdịnaya. Hydrocarbons elu na-edunruru ha na-adị ha kacha elu ma ọ bụrụ na ha enweghị ike ịbawanye ya, ma ọ bụrụ na regeneration gas na-enweghị ike ịbawanye ya dị ka fuel gas.
