·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.

·Tsarin Low-Temperature + Temperature Swing Adsorption (TSA):

Bayan rarraba kimiyyar molecular sieve, anza gas na raw bayan hada shi da plate-fin heat exchanger don sabbin sardawa, wanda ya haifar da partial condensation na C₅+ heavy hydrocarbons. Suna sardawa suka fito ta turbo-expander ko mixed refrigerant, kuma an farawa oil phase (recovering LPG/NGL) a cikin low-temperature separator. Wadannan hydrocarbons masu yawa da suke gas phase sun zinzegar da TSA molecular sieve adsorption tower, inda hydrocarbons masu yawa suna da loada selective adsorption. Gas mai sauƙi, tare da kwanaoyin hydrocarbon ≤ 20 mg/Nm³, an aika shi zuwa liquefaction unit. Bayan adsorption saturation, an amfani da gas mai zurfi mai nufi don reverse purging regeneration. Wadannan hydrocarbons da suka fito suna sardawa kuma sun karbarci, kuma an amfani da regeneration gas azaman abubuwar mutum.

·Lokacin Farasa, Sakawa da Kuwakar Bayan:

An rigaya su don assembly na fabirka da installation a wurin, don tabbatar da kungiyar sayayya. Jimlar lokacin aikin daga lokacin signing na kontrak zuwa successful commissioning shine 7 kwanan wata.
