I-Ethylene GlycolIindlela Ezisekelwe Kwi-Petroleum kunye NeeNjongo Zazo
I-ethylene glycol, eyaziwa ngokuba yi-glycol, sisixhobo esibalulekileyo esisisiseko sendalo kwishishini le-petrochemical. Ngenxa yexabiso eliguquguqukayo le-petroleum namhlanje, ukufumana indlela engabizi kakhulu yokuvelisa i-ethylene glycol kuye kwaba yindawo ephambili yophando. Eli phepha lihlalutya kwaye lithelekise iindlela ezisekelwe kwi-petroleum kunye nezingasekelwe kwi-petroleum zokuvelisa i-ethylene glycol, kwaye liphonononga izibonelelo kunye neengxaki zazo.

Iinkqubo ezi-1 ezisekelwe kwiPetroleum kwiMveliso ye-Ethylene Glycol
1.1 Ukufunxwa ngokuthe ngqo kwe-Ethylene Oxide
Le yindlela yendabuko yokuvelisa i-ethylene glycol enkulu. Kule nkqubo, i-ethylene oxide kunye namanzi zidityaniswe ngomlinganiselo we-molar we-1:20 ukuya kwi-1:22. I-ethylene oxide isabela ngokupheleleyo ukuze yenze umxube ongcolileyo, othi emva koko uphoswe yi-evaporation ezininzi ukuze uphelelwe ngamanzi emzimbeni kwaye uqhekeke kwi-vacuum ukuze kuveliswe i-ethylene glycol, kunye neemveliso ezingaphantsi ezifana ne-diethylene glycol kunye ne-triethylene glycol. Isivuno sisonke simalunga ne-88%.
Ukwandisa ubungakanani bamanzi kunokunciphisa ukwakheka kweemveliso eziphumayo kwaye kuphucule izinga lokuguqulwa kwe-ethylene oxide. Nangona kunjalo, igalelo elikhulu lamanzi lidala imingeni ebalulekileyo ekufumaneni iimveliso ezicocekileyo kakhulu. Ngaphezu koko, izixhobo zokwenza le nkqubo zifuna ii-evaporators ezininzi, kwaye kusetyenziswa amandla amaninzi ukwahlulahlula imveliso, nto leyo ekhokelela kwinkqubo enokuhamba kwexesha elide, utyalo-mali oluninzi lwezixhobo, kunye nokusetyenziswa kwamandla aphezulu.
