Processs oF TEG umwuma muri gaze naturel

Inzira oFKubura TEG muri gaze gasanzweni inzira isanzwe yo gukuramo amazi muri gaze gasanzwe.
Gazi isanzwe yuzuye itandukanijwe nigitonyanga cya 5 mm no hejuru ikanyura muyungurura hanyuma ikinjira mucyumba cyo gutandukanya gaze-amazi mu gice cyo hepfo yumunara wa triethylene glycol winjiza igice cya dehydrasiyo kugirango utandukanye amazi yubusa ashobora kuzanwa. umunara wo gukuramo iyo filteri itandukanya iri mumpanuka.Yinjira mu gice cyo gukuramo binyuze muri riser yumunara winjira.Triethylene glycol ivugururwa yatewe hejuru yikuramo kugirango ihure neza na gaze ya gazi yo hejuru-hejuru kugirango ikoreshwe kandi ihanahana amazi.Ubushuhe bwakuweho gaze karemano ikurwaho numunara wo hejuru wibicu 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 kigabanya ubushyuhe bwa triethylene glycol yinjira mu munara.Gazi isanzwe nyuma yo guhanahana ubushyuhe yinjira muyungurura kugirango itandukanya glycol yatwaye hanyuma ikinjira mumiyoboro yohereza hanze.Triethylene glycol ikungahaye ikurura amazi muri gaze karemano isohoka muminara yo kwinjiramo ikinjira murwego rwamazi agenga valve.Nyuma yo kwiheba, yinjira mu isahani yo gukonjesha hejuru yinkingi ikungahaye y’amazi meza, ihanahana ubushyuhe hamwe na parike ishyushye ikorwa muri reboiler, itanga ubushobozi bwo gukonjesha hejuru yinkingi, gushyuha kugeza kuri 50 and, 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 irasohoka, ikoreshwa nka gaze ya lisansi yo gutwika.
Amashanyarazi akungahaye ya triethylene glycol yinjira muyungurura kugirango akungurure umwanda, hanyuma yinjire muyungurura ya karubone kugirango yongere yongereho hydrocarbone yashonga muri triethylene glycol nibintu byangirika bya triethylene glycol.Noneho yinjira mu isahani ikungahaye kandi ikennye cyane kugirango ihindure ubushyuhe hamwe nubushyuhe bwo hejuru bwa triethylene glycol ivuye mu kigega cyo guhanahana ubushyuhe mu gice cyo hepfo ya reboiler ya triethylene glycol.Guhinduranya ubushyuhe bizamuka bigera kuri 120 ~ 130 ℃ kandi byinjira mu nkingi ikungahaye.
Muri reboiler ya triethylene glycol mugice cyo hepfo yinkingi ya distillation, glycol ya triethylene yashyutswe kugeza 193 and, hanyuma amazi yo muri triethylene glycol aracika kandi asohoka hejuru yinkingi ya distillation binyuze mu gucamo ibice byinkingi.Glycol yegamiye hamwe hamwe na 99% (WT) itembera hejuru yinkingi yamazi yometse kumurongo muri reboiler kugeza munsi ya triethylene glycol yo guhanahana ubushyuhe.Mugihe cyibikorwa bya gaze yumye mumurongo wamazi wamazi, ubunini bwa glycol yinini yinjira mubigega byubushyuhe birashobora kugera kuri 99.5% ~ 99.8%.
Muri tanker ya glycol, glycol itagira ubushyuhe hamwe nubushyuhe bwa 193 ℃ yinjira mubutunzi bukennye kandi bukennye kugirango bahindure ubushyuhe hamwe na glycol ikungahaye.Iyo ubushyuhe bugabanutse kugera kuri 100 ℃, bwinjira muri pompe.Lean triethylene glycol isunikwa mumashanyarazi ya gaz-yamazi yubushyuhe hanze ya pompe, ikonjeshwa nogusohora ubushyuhe bwa gaze, hanyuma ikinjira hejuru yimashini iva mugice cyo hejuru kugirango ikarangize.
Umugezi wa gazi yumye usohokera mu gice cyumuyaga wa gaz wumye ugasohokera hanyuma ukinjira mu muyoboro wo gushyushya gazi yumye ya tanki yo guhanahana ubushyuhe ku gice cyo hepfo ya rezoiler ya triethylene glycol.Nyuma yo gushyukwa na glyetine ya triethylene, irajugunywa kuri 0.4MPa binyuze mumashanyarazi ubwayo igenga valve hanyuma ikinjira mumatara ya gaze ya peteroli.Nyuma yo kuva muri peteroli ya gaze ya lisansi, igabanijwemo inzira ebyiri.Inzira imwe irashyuha kandi ikinjira mugice cyo hepfo cyimyanda itagabanije nkimyuka ya gazi;Ibindi ni gaze ya lisansi ikoreshwa nka reboiler.
