I-molecular distillationitekhnoloji ekhethekileyo yokwahlula ulwelo-ulwelo, eyahlukileyo kwidistillation yemveli exhomekeke kumgaqo wokwahlula umahluko wenqaku elibilayo. Le yinkqubo ye-distillation kunye nokuhlanjululwa kwezinto ezithintekayo ukushisa okanye izinto eziphezulu zokubilisa izinto usebenzisa umehluko kwindlela yamahhala ye-molecular motion phantsi kwe-vacuum ephezulu. Isetyenziswa kakhulu kwiikhemikhali, amayeza, i-petrochemical, iziqholo, iiplastiki kunye neoyile kunye namanye amashishini.
Izinto eziphathekayo zigqithiselwa ukusuka kwisitya sokutyisa ukuya kwi-distillation engundoqo ye-evaporator. Ngokujikeleza kwerotha kunye nokufudumeza okuqhubekayo, ulwelo lwemathiriyeli luyakhuhla lube yifilim elulwelo olucekethekileyo, olunesiphithiphithi, luze lutyhalelwe ezantsi kwimilo ejikelezayo. Kwinkqubo yokwehla, izinto ezikhaphukhaphu (ezinendawo yokubila ephantsi) kulwelo olubonakalayo luqala ukujika lube ngumphunga, lufudukele kwicondenser yangaphakathi, kwaye lube lulwelo oluqukuqela lusiya kwinqanaba lokukhanya lokufumana iflaski. Iimathiriyeli ezinzima (ezifana neklorofili, iityuwa, iswekile, i-waxy, njl. njl.) aziphumi zibe ngumphunga, endaweni yoko, zihamba ecaleni kodonga lwangaphakathi lwe-evaporator kwisigaba esinzima sokufumana iflaski.
