·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.

·Ndoro-ndoto Ose Osisi + Nkọwa nke Ndoro-ndoto (TSA):

N'kà egwuregwu na-egbu agwa, ihe omimi na-adị ya n'ime exchanger mmiri akpụkpọ maka precooling, na-enyere aka ikpuchi oke C₅+ hydrocarbons. Ezi uwe ha mgbe ahụ dị elu site na turbo-expander ma ọ bụ refrigerant zuru ezu, kama oil phase (irecovery LPG/NGL) na-adịghị n'ime separator mmiri elu. Hydrocarbons elu ole na-adị n'ime gas phase baa n'ime TSA molecular sieve adsorption tower, ebe hydrocarbons elu na-adị njikọrịta. Outlet gas, na ngwaahịa hydrocarbon elu ≤ 20 mg/Nm³, enwetakwara ya n'ime liquefaction unit. Mgbe adsorption na-eche echensu, purified gas na-edunruru enweghị ike ịbawanye ya n'aka ọdịnaya. Hydrocarbons elu na-edunruru ha na-adị ha kacha elu ma ọ bụrụ na ha enweghị ike ịbawanye ya, ma ọ bụrụ na regeneration gas na-enweghị ike ịbawanye ya dị ka fuel gas.

·Cryogenic Distillation maka ijiji Nitrogen:

N'kara ịrụsị karbon, agba nke mbọ na-agba ọsọ na anụnụ nke naitrojin na metan n'ime akwadụrụ nrụpụta mgbe ọ na-eme ntakpụrụ aka na achọkarị karbon nke ukwuu. O bugo na ngwaọrụ nkịtị aka nke uche, ebe ọ na-erụaka mkpa nke -162°C site na ngwaọrụ DMR na-agbasa oke ọcha ma bugo na ngwaahịa nke ngwaahịa naitrojin. Anụnụ nke naitrojin dị n'elu na-agbagharị n'ime condenser, mgbe metan dị n'elu na-evapọrịzị n'ime reboiler ma na-aga obere obere, na-emekarị njikọ distillation. Metan dị n'elu na-enwe obi ụtọ n'elu mmiri ma na-export dị ka agba njem. Anụnụ naitrojin dị n'elu na-ejikọta dị ka agba fuel mgbe enweghị ike ịdị n'elu nke ịgbasa oke ọcha, na-arụzi mmetụta oke ọcha.
