Inqubo ye-Glycol
I-Triethylene glycol noma i-diethylene glycol isetshenziselwa ukumunca nokukhipha amanzi kugesi yemvelo, okuyindlela evame ukusetshenziswa kakhulu yokuphelelwa amanzi yigesi yemvelo.
Ama-Glycol compounds anomuncwa omuhle wamanzi, okuhlanganisa i-ethylene glycol (isib.), i-diethylene glycol (DEG), i-triethylene glycol (TEG) kanye ne-tetraethylene glycol (Treg). Ngenxa yokuthi ukuphelelwa amanzi emzimbeni kwe-TEG kune-dew point drop enkulu kanye nezindleko zokutshalwa kwezimali eziphansi kanye nokusebenza, isetshenziswa kabanzi.
I-ethylene glycol isetshenziswa kakhulu ukufaka igesi yemvelo ukuvimbela ukwakheka kwe-hydrate;
I-Diethylene glycol kanye ne-triethylene glycol ziyasebenza ekuphelelweni kwamanzi kwegesi yemvelo enezimfuneko zokugeleza okukhulu kanye nokuwa okukhulu kwephuzu lamazolo esiteshini sokwelapha esiphakathi.

I-TEG Ukuphelelwa amanzi emzimbeni kubhekisela ekutheni igesi yemvelo ephelelwe amanzi emzimbeni iphuma phezulu kombhoshongo wokumunca bese iphuma kuyunithi ngemva kokushintshaniswa kokushisa kanye nokulawulwa kwengcindezi ngokusebenzisa i-lean liquid dry gas heat exchanger.
I-TEG ikhishwa phansi kwesithambisi. Ngemva kokungena kudivayisi elawula ingcindezi, isishintshisi sokushisa singena kusishintshisi sokushisa se-TEG esinothile futhi esimpofu. Ngemva kokudluliselwa kokushisa, singena embhoshongweni wokuvuselela i-TEG. Ohlelweni lokuvuselela, i-TEG iyaqina. Ngemva kokuvuselelwa, uketshezi olungenayo i-TEG alcohol lupholiswa yi-trial alcohol glycol ecebile futhi empofu bese lupholiswa ephampini elijikelezayo ukuze kulungiswe ingcindezi. Lapha sakha i-TEG, kanti i-TEG ngemuva kokulawulwa kwengcindezi ingena kusishintshisi sokushisa esingena uketshezi olungena igesi eyomile bese ingena futhi phezulu kombhoshongo wokumunca amanzi emzimbeni. Ngale ndlela, inqubo iqedela ukumunca, ukuvuselela kanye nokujikeleziswa kwe-TEG. Phakathi kwazo, umhwamuko wamanzi wegesi kanye nenani elincane legesi ye-hydrocarbon ekhishwa phezulu kombhoshongo wokuvuselela i-TEG.
Singochwepheshe ekuklameni, ekucwaningeni nasekuthuthukiseni, ekukhiqizeni, ekufakeni izinhlobo ezahlukene zokwelashwa kwemithombo yamafutha negesi, ekuhlanzweni kwegesi yemvelo, ekuphathweni kwamafutha aluhlaza, ekubuyiselweni kwe-hydrocarbon ekhanyayo, esitshalo se-LNG kanye nasejeneretha yegesi yemvelo.
