Kanjani futhi kungani kuncibilike amagesi

Liquefied igesi yemvelo ihamba ngokuthi ukudluliswa ke esimweni liquid ngaphansi isenzo lokushisa, amancani kuqhathaniswa anenani ezibucayi. Le nqubo yenza kube lula isipele bese ugcine it ukuze zisetshenziswe kamuva, kanye nenhlangano yezokuthutha kwanoma yiluphi uhlobo kwezithuthi. Ingqikithi livame ukusetshenziswa njengoba i-fuel okunye zezimoto, ekucubungululeni lensimbi iziteshi amandla mobile nokunye. Ngaphezu kwalokho, imizi eminingi yangasese kungatholakala e-LPG kubhayela. Izindleko yokudala izindawo zokukhiqiza kwawo kuxhomeke kulokho indawo ukuthuthukiswa, futhi uhlobo kanye nendlela okwakheke ngayo ekhishwe impahla eluhlaza. Okwamanje, ethembisayo yalezi babonwa elintantayo zokuthutha ngokwakha kwamanzi igesi amapayipi ngokuvamile ongenangqondo.

Ukulungiselela futhi kuqale liquefaction

izikimu kwetheknoloji izitshalo ukuthi ezisetshenziswa liquefaction kwesinye zihlukile, okokuqala kunakho konke, umjikelezo ifriji. ekukhetheni kwaKhe ngokuyinhloko inomthelela ukwakheka kanye yokucindezela igesi, yiwo ogelezela lapha. Lezi nemingcele, esikhundleni salokho, bathonywe izinto eziningana, phakathi okuyizinto sikhathi sonyaka, endaweni zokukhiqiza, ngisho eside sokuthuthuka. Ngaphambi kokuqala Ziyancibilika amagesi bese ithunyelwa isitshalo, kubalulekile ukuba zihlanzwe kusukela ukungcola esidi abakhwabanisi. Ngezinye ukuqala isigaba sayo yonke le nqubo izinto zokusetshenziswa inqwaba labelwe hydrocarbon kuhlanganise okusezingeni eliphezulu ukubila naphthenic, enamakha paraffinic. Kungenjalo odla kungenzeka nokuqiniswa amayunithi imishini. Ukuze ngokwamukelekile nangendlela kuncibilike amagesi, kumelwe kukhunjulwe ukuthi semali hydrocarbon esindayo ukubunjwa yabo kuholela okusezingeni eliphezulu lokushisa liquefaction futhi ukhwaliti energy nezindleko. Uma zihlanganisa khona nitrogen, kuholela simo esishubile futhi amandla owengeziwe.

Cascade indlela kanye nokupholisa imijikelezo

Ngo izinqubo zezimboni liquefaction olusekelwe phezu kwemiphumela yiyona ketshezi ukuhwamuka isimiso yenqubo adiabatic igesi ukunwetshwa, kanye Joule-Thomson umphumela. Liquefied igesi yemvelo ikhiqizwa ngokusebenzisa amaningi ifriji amayunithi (futhi kungakho imidiya). Kulokhu medium, esibonakala by aphansi ukuvala abacaphuni iwukufingqwa ngaphansi kwengcindezi ngenxa ukuhwamuka umakhelwane ukubila ephakeme. Le ndlela iyona ezivamile futhi njengoba liquefaction wendlale ezaziwayo. Ezimweni eziningi, le refrigerant e esigabeni sokuqala izenzo propane (ngezinye izikhathi ammonia), kanti eyesibili - ethylene. Ngakho, liquefaction Igesi yemvelo wenziwa Kulokhu ngaphansi kwethonya ethylene vaporized. Ngokuphathelene ifriji imijikelezo zakhelwe phezu Joule-Thomson umphumela okukhulunywe ngaye ngenhla, phakathi kwabo ukuhlukanisa kokubili nge nobunzima olulodwa futhi double, kanye pre-ukupholisa ngenxa ukusakaza akhethekile ejenti nezingahlobene nendaba.

Liquefaction ka ukufaka enkulu

amagesi Liquefied nakho kungase ngokusebenzisa kubangela umjikelezo owodwa threaded. Kube imele multicomponent refrigerant ingxube ehlanganisa i-nitrogen ne-hydrocarbon. Le ndlela ukushintshwa kwalo avame ukusetshenziswa ukufaka emikhulu, ukusebenza esiphakathi amabili nanhlanu million cubic metres of umkhiqizo osuphelile ngosuku. amagesi Liquefied ngale ndlela kuzuzisa ngokuya iphansana amandla izindleko. Ngakolunye uhlangothi, owodwa wendlale umjikelezo kudinga inani elikhulu imishini ukusetshenziswa metal.
