·MDEA Decarbonization Process Description:

Anan wuya taƙaita ana tsarawa ta hanyar mai tsarta kuma shiga sama a dakin tafinta, inda ta hadu da haɓakkin MDEA mai zurfiin waɗanda an sauya daga samma ta hanyar rukuwa mai kyau. CO₂ da H₂S ana karɓawa su ta wayar zaiyi. Anan haɓakkin mai zurfi ana rage shekara a cagalli mai rage don cassa hydrocarbons, sanya a cagalli mai nisa da haɓakkin mai zurfi, sannan sai shiga sama a dakin gyara mata. A kan yabo na biyu a cagalli mai nisa, CO₂ da H₂S ana farka su. Haɓakkin mai zurfi ya adana, ana canza, sanya, kuma an sauya shiga dakin tafinta don ci gaba. Gasa mai asidit din sama dake sama za a iya aika zuwa maye sauƙi ko kayayyakin CO₂.

·Bayani na Tsarin Kewayon Molecular Sieve:

Bayan hadarin carbon, an kusantar raw gas zuwa adsorption Tower A, inda an kaupe water ta hanyar molecular sieve bed. Dry gas mai gudu yana da water dew point ≤ -60°C kuma an aika shi zuwa down stream. Bayan adsorption saturation, Tower B za a canza zuwa regeneration process: dry gas ko nitrogen za a rage su a cikin heater kuma a amfani da su wajen reverse purging na molecular sieve bed. Za a rage water wanda aka desorb a cikin cooler. Daga bai, za a amfani da cold dry gas wajen forward cooling na bed har zuwa 40°C, kuma yanzu a dawo regeration domin sauya. Dual towers za su canzawa ne a atomatik ta hanyar programmed valves, tare da tsawon dugun 8–12 hours.
