（1） Kuchenesa zvinonyungudutsa zve organic

Inonyanya kushandisa zvinonyungudutsa zve organic kunyungudutsa mafuta akasviba neasina kupiswa kubvisa mavara emafuta. Zvinonyungudutsa zve organic zvinowanzo shandiswa zvinosanganisira ethanol, peturu yekuchenesa, toluene, carbon tetrachloride, trichloroethylene, nezvimwewo. Zvinonyungudutsa zvinoshanda zvakanyanya icarbon tetrachloride ne trichloroethylene, izvo zvisingatsvi uye zvinogona kushandiswa kubvisa mafuta pakupisa kwakanyanya. Zvinofanira kucherechedzwa kuti mushure mekubvisa mafuta ne organic solvent, mafuta ekuwedzera anofanirawo kubviswa. Kana solvent ikashanduka pamusoro pechubhu yerectangular, kazhinji pane firimu rakatetepa rinosara, rinogona kubviswa mumaitiro anotevera akadai sekuchenesa alkali uye kubviswa kwemafuta emagetsi.

（2） Kuchenesa kwemagetsi

Kubvisa mafuta eCathode kana kushandisa anode necathode neimwe nzira ndiko kunonyanya kushandiswa. Gasi rehydrogen rakaparadzaniswa necathode kana gasi reokisijeni rakaparadzaniswa neanode ne electrochemical reaction rinokurunga ne solution iri pamusoro pechubhu yerectangularkuti mafuta abude pamusoro pesimbi. Panguva imwe chete, mushonga wacho unoramba uchichinjana, izvo zvinoita kuti mafuta aite saponification uye emulsification. Mafuta asara achaparadzaniswa nesimbi pasi pesimba remabubbles anoparadzaniswa nguva dzose. Zvisinei, mukuita kwekubvisa mafuta mu cathodic, hydrogen inowanzopinda musimbi, zvichikonzera hydrogen embrittle. Kuti hydrogen imbrittle isashande, cathode ne anode zvinowanzo shandiswa kubvisa mafuta achichinjana.

（3） Kuchenesa alkaline

Nzira yekuchenesa yakavakirwa pakushanda kwemakemikari ealkali inoshandiswa zvakanyanya nekuda kwekushandiswa kwayo kuri nyore, mutengo wakaderera uye kuwanikwa kuri nyore kwezvinhu zvakagadzirwa. Sezvo nzira yekugeza alkali ichienderana ne saponification, emulsification uye mamwe mabasa, alkali imwe chete haigone kushandiswa kuita zvataurwa pamusoro apa. Zvikamu zvakasiyana-siyana zvinowanzo shandiswa, uye zvimwe zvinowedzera senge surfactants dzimwe nguva zvinowedzerwa. Alkalinity inosarudza mwero we saponification reaction, uye alkalinity yakakwira inoderedza kushushikana kwepamusoro pakati pemafuta nemushonga, zvichiita kuti mafuta ave nyore kubatanidza. Pamusoro pezvo, mushonga wekuchenesa unoramba uri pamusoro pechikamu chine mhango cherectangularinogona kubviswa nekusukwa nemvura mushure mekusukwa nealkali.

（4） Kuchenesa surfactant

Iyi inzira inoshandiswa zvakanyanya yekubvisa mafuta nekushandisa hunhu hwesurfactant senge kusimba kwepasi, kunyorova zvakanaka uye kugona kwakasimba kwe emulsifying. Kuburikidza ne emulsification ye surfactant, mask yechiso che interfacial ine simba rakati wandei inogadzirwa pa oil-water interface kuti ichinje mamiriro e interface, kuitira kuti zvidimbu zve oil zviparadzirwe mumvura kuti zvigadzire emulsion. Kana kuburikidza nekunyungudika kwe surfactant, mavara e oil haanyungudike mumvura pachubhu yerectangularinonyungudutswa mu micelle inonyungudutswa, kuitira kuti iendese tsvina yemafuta kune mhinduro yemvura.
