Solvent extraction method
Nzira yekushandisa organic solvents kubvisa uye kuparadzanisa chinhu chakabviswa kubva kune immiscible aqueous solution inonzi organic solvent liquid-liquid extraction method, yakapfupikiswa senzira yekubvisa solvent. Iyi inzira yekutamisa zvinhu kubva pachikamu chemvura kuenda pane chimwe.
Solvent yekubvisa yakashandiswa kare mu petrochemical indasitiri, organic chemistry, mishonga chemistry uye analytical chemistry. Nekudaro, mumakore makumi mana apfuura, nekuda kwekuvandudzwa kweatomu yesimba sainzi uye tekinoroji, kudiwa kwezvinhu zveultrapure uye kugadzirwa kwezvinhu, kudhirowa kwesolvent kwakagadzirwa zvakanyanya muindasitiri yemafuta enyukireya, isingawanzo simbi uye mamwe maindasitiri.
Kuenzaniswa nemaitiro ekuparadzanisa akadai sekunaya kwegiredhi, graded crystallization, uye ion exchange, solvent extraction ine nhevedzano yezvakanakira seyakanaka kupatsanurwa maitiro, yakakura kugadzirwa kugona, nyore kukurumidza uye kuenderera kugadzirwa, uye nyore kuwana otomatiki kutonga. Nokudaro, zvishoma nezvishoma yave nzira huru yekuparadzanisa huwandu hwakawanda hwepasi risingawanzoitiki.
Iyo yekuparadzanisa midziyo ye solvent extraction method inosanganisira kusanganisa kujekesa tangi, centrifugal extractor, etc. Zvinyorwa zvinoshandiswa pakuchenesa pasi risingawanzo zvinosanganisira: cationic extractants inomiririrwa ne acidic phosphate esters yakadai seP204 neP507, anion exchange liquid N1923 inomiririrwa nemaamine, uye zvinonyungudutsira. inomiririrwa neakarerekera phosphate esters akadai TBP uye P350. Izvi zvinotora zvine viscosity yakakwira uye density, zvichiita kuti zviome kupatsanura kubva mumvura. Kazhinji inonatswa uye inoshandiswa zvakare nezvinonyungudutsa zvakaita separafini.
Maitiro ekubvisa anogona kazhinji kukamurwa kuita matanho makuru matatu: kudhirowa, kuwacha, uye kudzosera kumashure. Mineral raw materials yekuchera isingawanzo simbi dzepasi uye dzakaparadzirwa zvinhu.
