Umgangatho oPhakamileyo waseTshayina weSixhobo sokuFakelwa kweGesi yeNdalo abaThumela ngaphandle - i-3 MMSCD yesiXhobo esiFakelweyo seGesi yokuSetyenziselwa iGesi yeNdalo – eRongteng

Inkqubo yeGlycol

I-Triethylene glycol okanye i-diethylene glycol isetyenziselwa ukufunxa kunye nokususa amanzi kwi-gesi yendalo, eyona ndlela isetyenziswa ngokuqhelekileyo kwigesi yendalo.
I-Glycol compounds ine-absorption efanelekileyo yamanzi, kuquka i-ethylene glycol (umzekelo), i-diethylene glycol (DEG), i-triethylene glycol (TEG) kunye ne-tetraethylene glycol (Treg). Ngenxa yokuba i-TEG dehydration inokwehla okukhulu kombethe kunye notyalo-mali olusezantsi kunye neendleko zokusebenza, isetyenziswa kakhulu.
I-Ethylene glycol isetyenziselwa ukujova igesi yendalo ukukhusela ukubunjwa kwe-hydrate;
I-Diethylene glycol kunye ne-triethylene glycol zisebenza ekuphelelweni kwamanzi kwegesi yendalo kunye nokuhamba okukhulu kunye neemfuno ezinkulu zokulahla umbethe kwisikhululo sonyango esiphakathi.

Iimbonakalo:

I-TEG Ukuphelelwa ngamanzi emzimbeni kubhekiselele ekubeni irhasi yendalo ephelelwe ngamanzi iphuma kumphezulu wenqaba yokufunxa kwaye iphuma kwiyunithi emva kokutshintshiselana kobushushu kunye nolawulo loxinzelelo ngolwelo olubhityileyo olunobushushu berhasi eyomileyo.

I-TEG ikhutshwe ezantsi kwe-absorber. Emva kokungena kwisixhobo sokulawula uxinzelelo, umtshintshi wobushushu ungena kwi-TEG etyebileyo kunye nehlwempuzekileyo. Emva kokudluliselwa kobushushu, ingena kwi-TEG yokuvuselela inqaba. Kwinkqubo yokuhlaziya, i-TEG iyajiya. Emva kohlaziyo, i-TEG yolwelo olungekho mgangathweni lotywala lupholiswa zi-alcohol ezintathu ze-glycol ezityebileyo kunye nolwelo oluhlwempuzekileyo lokutshintshiselana kobushushu kwaye lupholile kwimpompo ejikelezayo ukulungisa uxinzelelo. Apha senza i-TEG, kwaye i-TEG emva kokulawulwa koxinzelelo ingena kwi-gas eyomileyo e-lean liquid exchanger kwaye iphinda ingene phezulu kwi-dehydration absorption tower. Ngale ndlela, inkqubo igqibezela ukufunxwa, ukuhlaziywa kunye nokujikeleziswa kwe-TEG. Phakathi kwabo, umphunga wamanzi egesi kunye nenani elincinci legesi ye-hydrocarbon ekhutshwe phezulu kwi-TEG yokuvuselela inqaba.

Sisebenza ngokukhethekileyo kuyilo, i-R & D, imveliso, ukufakwa kweentlobo ezahlukeneyo ze-oyile kunye ne-gas field wellhead unyango, ukucocwa kwegesi yendalo, unyango lwe-oyile ekrwada, ukukhanya kwe-hydrocarbon recovery, isityalo se-LNG kunye nejenereyitha yegesi yendalo.
