Inkqubo yeGlycol
I-Triethylene glycol okanye i-diethylene glycol isetyenziselwa ukufunxa nokususa amanzi kwigesi yendalo, eyona ndlela isetyenziswa kakhulu ekupheliseni amanzi kwigesi yendalo.
Iikhompawundi zeGlycol zifunxa kakuhle amanzi, kuquka i-ethylene glycol (umz.), i-diethylene glycol (DEG), i-triethylene glycol (TEG) kunye ne-tetraethylene glycol (Treg). Ngenxa yokuba ukuphelelwa ngamanzi kwi-TEG kune-dew point drop enkulu kunye neendleko zotyalo-mali eziphantsi kunye nokusebenza, isetyenziswa kakhulu.
I-ethylene glycol isetyenziswa kakhulu ukufaka igesi yendalo ukuthintela ukwakheka kwe-hydrate;
I-Diethylene glycol kunye ne-triethylene glycol ziyasebenza ekuphelisweni kwegesi yendalo ene-flow enkulu kunye neemfuno ezinkulu ze-dew point drop kwisikhululo sonyango esiphakathi.
Iimbonakalo:
Ukuphelelwa ngamanzi emzimbeni kwe-TEG kubhekisa ekubeni igesi yendalo ephelelwe ngamanzi emzimbeni iphuma phezulu kwinqaba yokufunxa kwaye iphume kwiyunithi emva kokutshintshana kobushushu kunye nolawulo loxinzelelo ngesixhobo sokutshintsha ubushushu segesi esomileyo esingenamanzi.
I-TEG ikhutshwa ezantsi kwesixhobo sokufunxa. Emva kokungena kwisixhobo esilawula uxinzelelo, isixhobo sokufudumeza singena kwisixhobo sokufudumeza se-TEG esityebileyo nesingenamandla. Emva kokudluliselwa kobushushu, singena kwinqaba yokuvuselela i-TEG. Kwinkqubo yokuvuselela, i-TEG iyaqina. Emva kokuvuselelwa, ulwelo olungenamandla lwe-TEG alcohol lupholiswa yi-three alcohol glycol enobutyebi nolungenamandla kwaye lupholiswe kwimpompo ejikelezayo ukuze kulungiswe uxinzelelo. Apha senza i-TEG, kwaye i-TEG emva kokulawulwa koxinzelelo ingena kwisixhobo sokufudumeza ubushushu solwelo olungenamandla lwegesi eyomileyo kwaye iphinde ingene phezulu kwinqaba yokufunxa amanzi emzimbeni. Ngale ndlela, inkqubo igqibezela ukufunxa, ukuhlaziya kunye nokujikeleza kwe-TEG. Phakathi kwazo, umphunga wamanzi wegesi kunye nenani elincinci legesi ye-hydrocarbon ekhutshwa phezulu kwinqaba yokuvuselela i-TEG.
Siziingcali kuyilo, uphando nophuhliso, ukuvelisa, ukufakela iintlobo ngeentlobo zonyango lwe-oyile kunye negesi, ukucocwa kwegesi yendalo, unyango lwe-oyile ekrwada, ukubuyiswa kwe-hydrocarbon ekhanyayo, isityalo se-LNG kunye nejenereyitha yegesi yendalo.
