Gazi karemano itose mu gihe yuzuye itandukanyijwe n'icyuma gitandukanya icyuma kugira ngo gitandukanye ibitonyanga by'amazi bya 5 μm no hejuru, hanyuma kinjire mu cyumba gitandukanya gazi n'amazi kiri hasi ya Umunara wo kwinjiza TEG (Triethylene gly) bya ishami rishinzwe kuvura amazi gutandukanya amazi yigenga ashobora kuzanwa mu munara wo kwinjizamo umwuka iyo icyuma gitandukanya icyuma kiri mu mpanuka. Injira mu gice cyo kwinjizamo umwuka unyuze mu ntera y'umunara wo kwinjizamo umwuka. TEG yavuguruwe ishyirwa hejuru y'umunara wo kwinjizamo umwuka kugira ngo ihuze neza na gazi karemano uhereye hasi ugana hejuru ku munara wo kwinjizamo umwuka kugira ngo yohereze kandi ikuremo ubushuhe. Gazi karemano yakuwemo amazi iva mu munara nyuma yo gukuraho ibitonyanga bya glycol birenga 5 μ m binyuze mu gikoresho cyo gufata amazi hejuru y'umunara.
Nyuma yo kuva mu munara, ubushyuhe buhererekanywa na glycol ishyushye mbere yo kwinjira mu munara unyuze mu cyuma gihindura ubushyuhe cy’ingufu kugira ngo bigabanye ubushyuhe bwa TEG bwinjira mu munara. Nyuma yo guhindura ubushyuhe, gazi karemano yinjira mu cyuma gitandukanya icyuma gitwara gazi karemano kugira ngo gitandukanye glycol itwara hanyuma kinjire mu muyoboro wo kohereza hanze. TEG ikungahaye, yinjiza ubushuhe buri muri gazi karemano, isohoka mu munara wo kwinjizamo amazi ikinjira mu cyuma gipima urwego rw’amazi. Nyuma yo gukuraho umuvuduko, yinjira mu cyuma gikonjesha kiri hejuru y’inkingi ikungahaye ku binyabutabire kugira ngo ihindure ubushyuhe n’umwuka ushyushye uva mu cyuma gihindura gazi. Nyuma yo gutanga ubushobozi bwo gukonjesha bw’ingufu zo hejuru y’inkingi, TEG ikungahaye ishyushya kugeza kuri 50 ℃. Umuyoboro w’amazi winjira mu cyuma gihindura gazi cya TEG. Glicol ikungahaye iragabanuka kugeza kuri 0.4MPa ~ 0.6MPa mu cyuma gihindura gazi. Gazi ya Hydrocarbon n’indi myuka ishongeshejwe muri TEG irashya, kandi iyi myuka ikoreshwa nk’imyuka ikoreshwa mu gutwika gazi.
Nyuma yo kugurumana, TEG y'amazi akungahaye ku bushyuhe yinjira muri firigo ya mashini kugira ngo isukure imyanda ya mashini, hanyuma ijya muri firigo ya karuboni ikoreshwa kugira ngo irusheho kwinjiza ibintu bya hydrocarbon byashongeshejwe muri TEG n'ibintu byangiritse bya TEG. Hanyuma yinjira muri firigo irimo ubushyuhe bwinshi n'ubuke bw'amazi kugira ngo ihindure ubushyuhe na TEG ifite ubushyuhe bwinshi iva mu gikoresho cyo hasi cyo guhindurira ubushyuhe cya TEG. Ubushyuhe bwo guhindurira ubushyuhe buriyongera kugera kuri 120 ~ 130 ℃ hanyuma ijya mu gice cy'amazi akungahaye ku bushyuhe.
Mu cyuma gishyushya TEG kiri hepfo y’inkingi yo gushyushya, TEG ishyushya kugeza kuri 193 ℃, maze amazi ari muri TEG agakurwamo ibice hanyuma agasohoka hejuru y’inkingi yo gushyushya. Ingano ya 99% (WT) ya glycol yoroheje ishyirwa mu kigega cyo hasi cya TEG cy’ubushyuhe n’inkingi yo gushyushya amazi yoroheje iri muri icyo cyuma. Mu gihe umwuka wumutse uri mu nkingi yo gushyushya amazi yoroheje, ingano ya glycol yoroheje yinjira mu kigega cyo gushyushya ishobora kugera kuri 99.5% ~ 99.8%.
Mu gikoresho cya glycol buffer, glycol yoroheje ifite ubushyuhe bwa dogere 193 ℃ yinjira mu gikoresho gishyushya ubushyuhe cya glycol gikungahaye kandi kibi kugira ngo gihanagure ubushyuhe na glycol yiyongereyeho. Iyo ubushyuhe bugabanutse bukagera kuri dogere 100 ℃, yinjira mu ipompo. Ifu yoroheje ya TEG ishyirwa mu gikoresho gishyushya ubushyuhe cya gaze-liquid cyo hanze cy'umunara wo kwinjiza hakoreshejwe ipompo. Nyuma yo gukonjesha hakoreshejwe imashini ishyushya ubushyuhe ya gaze ivuye mu munara, yinjira hejuru y'umunara wo kwinjiza uturutse hejuru y'umuyoboro wo gufunga kugira ngo yuzuze imikorere y'umushongi.
Umugezi wa gazi yumye uva mu gice cy’umwuka wumye aho umunara usohoka, ukinjira mu muyoboro w’umwuka wumye ushyushya ikigega cy’ubushyuhe kiri hasi mu gice cyo hasi cya TEG reboiler. Nyuma yo gushyushya na TEG yoroheje, ishyirwa kuri 0.4MPa hakoreshejwe valve igenzura umuvuduko hanyuma ikinjira mu kigega cy’umwuka wumisha. Nyuma yo kuva mu kigega cy’umwuka wumisha, igabanywamo inzira ebyiri, imwe muri zo ishyushywa ikinjira mu gice cyo hasi cya lean liquid stripping column nk’lean liquid stripping gaze, indi ikaba nk’umwuka wumisha. Iyi ni inzira ya amazi akuraho gazi karemano.
