Sistemụ pretreatment nri gas
Usoro usoro ahọrọ maka usoro eruba nkenri gas pretreatment usoronwere njirimara ndị a:
(1) Tụnyere usoro MEA, usoro MDEA nwere njirimara nke obere ụfụfụ, obere corrosion na obere mfu amine.
(2) Ngalaba ahụ na-anabata MDEA wet decarburization, na enweghị oriri nke regeneration gas.
