Iyali Na Gwamnati Na Gas: 4 Sistemin Da A Bayyana Su

Shararar Mataki

·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.

·Cryogenic Distillation don dolewa na Nitrogen:

Bayan haular da keɓaɓɓen karbon, yankin gasi ya kai tsauraran da sararin naitrojin da mafanin metanu a cikin jagorar gwaji don samun tsawon shango da kuma baya da wani doki na kayan da keɓaɓɓen karbon. Sai dai shi zai shiga cikin sararin sanyawa, inda ya kama zuwa -162°C ta hanyar DMR mai amfani da abubuwan sanya da sauran irin sanyawa kuma shiga a tsakiyar tura ta naitrojin. Sararin naitrojin ya kai tsauraran a cikin condenser, yayin da mafanin metanu ya kai tsauraran a cikin reboiler kuma ya taga sama, yayin da ke kammala tsari na distillation. Mafanin metanu ya kama zuwa tsawon shango kuma an export shi kamar gasi na abokin ciniki. Sararin gasi na naitrojin waje ya yi amfani da shi kamar gini mai chafe bayan kaiwar sa hannun cold energy a cikin expander, don samun balance na iyaka ta hankali.

·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.
