·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.

·Nkọwa nke ọrụ dehydration Molecular Sieve:

N'ikpeazụ ịghapụ karbon, ihe omimi na-adịghị nke ọma na-agbata n'ime Tower A, ebe mmiri na-agbanwe agbane site n'akwụkwọ mmanya molecular sieve. Ihe omimi na-esi n'elu na-enweghị mmiri elu igwe ≤ -60°C ma si na-egosi ya n'elu. N'ikpeazụ ịgbatama, Tower B gbagharị na njikwa: ihe omimi ma ọ bụ nitrogen na-emepụta n'ime ugbo mmiri wee jikọta ya maka ịkpachara akwụkwọ mmanya molecular sieve. Mmiri a na-ekpuchi ya na-agbanwe na-agbanwe n'ime cooler. Nkeji, ihe omimi osisi osisi na-ejikarị maka ịgbachite akwụkwọ mmanya ruo 40°C, emechitela njikwa maka ntanetanee. Ndị otu abụọ anaghị ekwe omume ịbawanye site n'ime valves ndị na-akpaghị akpa, na oge mbụ 8–12 awa.
