Inzira oFUmwuka wa TEG muri gaze karemanoni inzira isanzwe yo gukuramo amazi muri gaze gasanzwe.
Gazi isanzwe yuzuye itandukanijwe nigitonyanga cya 5 mkm no hejuru ikanyura muyungurura hanyuma ikinjira mucyumba cyo gutandukanya gaze-amazi mu gice cyo hepfo yumunara wa triethylene glycol winjiza igice cya dehidrasi kugirango utandukanye amazi yubusa ashobora kuzanwa. umunara wo kwinjizamo mugihe uyungurura utandukanya uri mumpanuka. Yinjira mu gice cyo gukuramo binyuze muri riser yumunara winjira. Triethylene glycol yavuguruwe yatewe hejuru yimashini kugirango ihure neza na gaze gasanzwe yo hejuru-hejuru kugirango ikoreshwe kandi ihanahana amazi. Ubushuhe bwakuweho gaze karemano ikurwaho numunara wo hejuru ufata ibicu hejuru ya 5 μm glycol itonyanga muminara.
Nyuma yo kuva ku munara, ihanahana ubushyuhe hamwe na glycol ishyushye mbere yo kwinjira mu munara unyuze mu cyuma gipima ubushyuhe kugira ngo igabanye ubushyuhe bwa triethylene glycol yinjira mu munara. Gazi isanzwe nyuma yo guhanahana ubushyuhe yinjira muyungurura kugirango itandukane glycol yatwaye hanyuma yinjira mumiyoboro yohereza hanze. Triethylene glycol ikungahaye ikurura amazi muri gaze gasanzwe isohoka mu munara winjira ikinjira mu rwego rwamazi igenga valve. Nyuma yo kwiheba, yinjira mu isahani yo gukonjesha hejuru yinkingi ikungahaye y’amazi meza, ihanahana ubushyuhe hamwe n’amazi ashyushye yabyaye muri reboiler, itanga ubushobozi bwo gukonjesha hejuru yinkingi, ishyuha kugeza kuri 50 ℃, kandi umuyoboro usohoka winjira muri triethylene glycol flash tank. Glycol ikungahaye cyane kuri 0.4MPa ~ 0.6MPa muri flash tank, hanyuma gaze ya hydrocarubone hamwe nindi myuka yashonga muri triethylene glycol irashya, ikoreshwa nka gaze ya lisansi yo gutwika reboiler.
Amashanyarazi akungahaye ya triethylene glycol yinjira muyungurura kugirango akungurure umwanda, hanyuma yinjire muyungurura ya karubone kugirango yongere yongere hydrocarbone yashonga muri triethylene glycol nibintu byangirika bya triethylene glycol. Noneho yinjira mu isahani ikungahaye kandi idahwitse ihinduranya ubushyuhe kugirango ihindure ubushyuhe hamwe nubushyuhe bwo hejuru bwa triethylene glycol iva mu kigega cyo guhanahana ubushyuhe ku gice cyo hepfo ya reboiler ya triethylene glycol. Guhana ubushyuhe bizamuka kugera kuri 120 ~ 130 ℃ kandi byinjira mu nkingi ikungahaye y'amazi.
Muri triethylene glycol reboiler mugice cyo hepfo yinkingi ya distillation, glycol ya triethylene yashyutswe kugeza 193 and, kandi amazi yo muri triethylene glycol yacitsemo ibice hanyuma asohoka hejuru yinkingi ya distillation binyuze mu gucamo ibice byinkingi. Lean glycol yibitseho hafi 99% (WT) itemba iva mu nkingi zamazi zidafite inkingi muri reboiler kugeza munsi ya triethylene glycol yo guhanahana ubushyuhe. Mubikorwa bya gaze yumye mumurongo wamazi wamazi, ubunini bwa glycol yinini yinjira mubigega byo guhanahana ubushyuhe bishobora kugera kuri 99.5% ~ 99.8%.
Mu kigega cya glycol, glycol itagira ubushyuhe ifite ubushyuhe bugera kuri 193 ℃ yinjira mu bahinduzi ba glycol bakize kandi bakennye kugira ngo bahanahana ubushyuhe na glycol ikungahaye. Iyo ubushyuhe bugabanutse kugera kuri 100 ℃, bwinjira muri pompe. Lean triethylene glycol isunikwa mumashanyarazi ya gazi-yamazi hanze ya pompe, ikonjeshwa noguhindura ubushyuhe bwa gaze isohoka, hanyuma ikinjira hejuru yimashini iva mugice cyo hejuru cyikariso kugirango irangize kuzenguruka.
Umugezi wa gazi yumye uvanwa mu gice cyumuyaga wa gazi wumye ku isohoka ryinjira hanyuma ukinjira mu muyoboro wo gushyushya gaz wumye wa tanki yo guhanahana ubushyuhe mu gice cyo hepfo ya reboiler ya triethylene glycol. Nyuma yo gushyukwa na gly tricol triethylene, ijugunywa kuri 0.4MPa ikoresheje umuvuduko ukorera wigenga igenga valve hanyuma ikinjira mu kigega cya peteroli. Nyuma yo kuva mu kigega cya gaze ya lisansi, igabanijwemo inzira ebyiri. Inzira imwe irashyuha kandi ikinjira mugice cyo hepfo cyimyanda yamazi yinkingi nka gaze ya gazi yamazi; Ibindi ni gaze ya lisansi ikoreshwa nka reboiler.
