Distillation yog ib txoj hauv kev sib cais cov khoom sib xyaw los ntawm sublimating lub boiling point ntawm ib yam khoom. Nws yog dav siv nyob rau hauv kev lag luam, thiab ib qho kev siv cheeb tsam yog khib nyiab roj distillation.
Cov roj khib nyiab pov tseg yog cov cuab yeej siv hluav taws xob ruaj khov thiab zoo ib puag ncig uas tuaj yeem hloov cov roj pov tseg, cov roj lubricants, thiab cov khoom pov tseg rau hauv cov khoom siv rov qab siv dua. Niaj hnub no, cov thev naus laus zis no tau siv ntau txoj hauv kev los pab txo cov khoom pov tseg thiab txhawb kev txhim kho kev lag luam ncig.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov cuab yeej siv hluav taws xob pov tseg yog nws cov phooj ywg ib puag ncig. Vim tias nws siv lub hauv paus ntsiab lus ntawm thermal decomposition, nws tsis tas yuav tsum tau siv cov tshuaj los yog lwm yam teeb meem, yog li nws muaj cov khoom tsis muaj kuab paug zoo. Tsis tas li ntawd, cov cuab yeej no tseem tuaj yeem hloov cov emissions mus rau hauv kev hloov pauv lossis siv tau, yog li txo qhov hnyav ntawm ib puag ncig.
Raws li peb txhua tus paub, kev tiv thaiv ib puag ncig tau dhau los ua txoj haujlwm tseem ceeb rau cov tebchaws thoob ntiaj teb. Yog li ntawd, kev siv cov roj khib nyiab tshuab distillation yog qhov tseem ceeb, tsis yog los daws cov teeb meem ib puag ncig xwb, tab sis kuj coj tib neeg noj qab haus huv thiab ntsuab yav tom ntej.
