Umgangatho oPhezulu waseTshayina weSixhobo seGesi yeNdalo eSweetening ngaphandle - i-TEG dehydration skid - Rongteng

Inkcazo

I-TEG dehydration skid sisixhobo esiphambili ekucoceni igesi yendalo okanye unyango lwegesi yendalo. I-TEG dehydration skid yegesi yokutya imanzi ukuhlanjululwa kwegesi yendalo, kwaye umthamo weyunithi yi-2.5 ~ 50 × 104. I-elasticity yokusebenza yi-50-100% kwaye ixesha lokuvelisa lonyaka liyi-8000 iiyure.

I-TEG dehydration skid ithatha malunga ne-99.74% (wt) i-triethylene glycol (i-teg dehydrating agent, isusa awona manzi ahluthayo kukucoca igesi yendalo emanzi, ukucocwa nge-TEG absorber emva kokuphelelwa ngamanzi emzimbeni kwegesi eyomileyo (kwimeko yoxinzelelo lombethe kwindawo yefektri

Itshathi equkuqelayo

Emva kokufunxwa kwamanzi, i-TEG ihlaziywa ngendlela yoxinzelelo lwe-atmospheric yokufudumala ityhubhu yomlilo kunye nokuvuselelwa. Emva kokutshintshiselana kobushushu, ulwelo oluphele ubushushu luyapholiswa luze lubuyiselwe kwi-TEG yokufunxa inqaba emva koxinzelelo lokuphinda kusetyenziswe.

Amacandelo e-gas-forming aveliswa ngokuhlaziywa kolwelo olutyebileyo ikakhulu ngumphunga wamanzi kwaye aqulethe ixabiso elincinci le-hydrocarbons kunye neegesi.

Ukuze kupheliswe iingozi ezinokubakho zokhuseleko kunye nokuphepha ukukhutshwa ngokuthe ngqo kokungcoliseka kwendalo, irhasi yenkunkuma esetyenzisiweyo kwisixhobo sokubuyisela isulfure ikhutshelwa kwi-atmosfera emva kokutshisa kwi-exhaust gas burning oven.

Iimbonakalo

1. Inkqubo ye-TEG yokuphelelwa ngamanzi emzimbeni ilula, itekhnoloji evuthiweyo, xa kuthelekiswa nenye indlela yokuphelelwa ngamanzi emzimbeni inokufumana ukuhla kombethe okukhulu. Ukuzinza kakuhle kwe-thermal. Kulula ukuyihlaziya kwaye ineenzuzo zelahleko encinci, utyalo-mali oluphantsi kunye neendleko zokusebenza.

2. I-lean / rich liquid exchanger heat exchanger ifakwe phambi kokuba i-lean liquid circulating pump, engaphuculi kuphela iimeko zokusebenza zepompo ejikelezayo, kodwa inyusa izinga lokushisa le-TEG elityebileyo lolwelo kwi-triethylene glycol regenerator, ngokufanelekileyo ukubuyisela inxalenye yobushushu kunye nokunciphisa ukusetyenziswa kwegesi yegesi yokuvuselela.

3. Cwangcisa icebo lokucoca kumjelo otyebileyo wolwelo ukususa ukungcola komatshini kunye neemveliso zokonakala ezithwalwe kwinkqubo yesisombululo, gcina isisombululo sicocekile kwaye sithintele isisombululo kwi-foaming, enokunciphisa ilahleko ye-solvent kwaye ilungele ukusebenza okuzinzileyo kwexesha elide lesixhobo.Indlela yokufudumala ityhubhu yomlilo ngokuthe ngqo eyamkelwe kwi-TEG yokuvuselelwa ikhulile, ithembekile kwaye kulula ukuyisebenzisa.
