Ethylene Glycol Kunyoroveswa Kwakananga kweEthylene Oxide.

Ethylene GlycolNzira Dzinoshandiswa Pakugadzira Mafuta Uye Zvadzinotarisira
Ethylene glycol, inozivikanwawo seglycol, chinhu chakakosha che organic muindasitiri ye petrochemical. Zvichienderana nemutengo wepetroleum usingachinji nhasi, kutsvaga nzira inodhura yekugadzirwa kwe ethylene glycol kwave chinhu chinonyanya kufarirwa mukutsvaga. Pepa iri rinoongorora uye rinoenzanisa nzira dzekugadzira ethylene glycol dzinobva mu petroleum nedzisiri dze petroleum, uye rinoongorora zvakanakira nezvakaipa zvadzo.

Iyi ndiyo nzira yechinyakare yekugadzira ethylene glycol yakakura. Mukuita uku, ethylene oxide nemvura zvinosanganiswa mu molar ratio ye1:20 kusvika 1:22. Ethylene oxide inoita zvese kuti igadzire musanganiswa usina kuchena, uyo unozobva waiswa mumhepo yakawanda kuti mvura ipere uye vacuum fractionation kuti ibudise ethylene glycol, pamwe chete nezvimwe zvinhu zvakaita se diethylene glycol ne triethylene glycol. Mugove wese ungangoita 88%.

Kuwedzera huwandu hwemvura kunogona kuderedza kuumbwa kwezvigadzirwa uye kuwedzera mwero wekushandurwa kwe ethylene oxide. Zvisinei, mvura yakawanda inopinda inokonzera matambudziko makuru pakuwana zvigadzirwa zvine hutsanana hwakawanda. Uyezve, michina yekugadzira iyi nzira inoda ma evaporator akawanda, uye simba rakawanda rinoshandiswa pakuparadzanisa chigadzirwa, zvichikonzera nzira ine kufamba kwenguva refu, mari yakawanda yemidziyo, uye kushandiswa kwesimba rakawanda.
