Cov tuam txhab tshuaj siv cov khoom siv distillation, feem ntau hu ua tshuab distillation, kom rov qab cov kuab tshuaj. Distillation ua hauj lwm los ntawm cua sov cov kuab tshuaj mus rau nws boiling point, cia nws evaporate, thiab ces cia nws condense rov qab mus rau hauv lub xeev kua, uas yog ces sau thiab ua tiav. Kev tshem tawm cov kab mob, kev faib cov kua dej, thiab cov kev daws teeb meem tsuas yog qee qhov kev siv rau distillation apparatus. Nws yog ib qho cuab yeej tseem ceeb rau ntau yam kev lag luam, xws li petrochemical, tshuaj, thiab khoom noj khoom haus.
Muaj ntau ntau yam khoom siv distillation nyob rau hauv kev ua lag luam, suav nrog cov feem, batch, thiab tas li distillation. ntawm cov cuab yeej muaj qhov tshwj xeeb zoo thiab yog siv rau qee lub hom phiaj. distillation yog siv rau cov khoom me me, thaum cov khoom siv rau kev ua kom tsis tu ncua yog siv rau cov khoom loj ntawm cov kuab tshuaj rov qab. ntawm lawv cov ntsiab lus kub, cov khoom sib txawv ntawm cov tshuaj raug muab cais siv cov khoom siv fractional distillation.
Hauv cov chaw tshuaj lom neeg thiab cov chaw kuaj mob, cov khoom siv distillation feem ntau siv los rov qab cov kuab tshuaj. Nws yog ib qho tsim nyog rau kev tsim ntawm ntau lub tebchaw, xws li cov xim, cov kua roj vanish, thiab cov tshuaj. Cov txiaj ntsig tseem ceeb ntawm kev siv cov khoom siv distillation suav nrog txo cov khoom pov tseg thiab txuag nqi.
Txawm li cas los xij, kev tuav tsis raug ntawm cov khoom siv distillation yuav ua rau muaj teeb meem kev nyab xeeb. Cov cua kub kub ntawm cov kuab tshuaj flammable yog ib kauj ruam hauv cov txheej txheem uas yuav ua rau hluav taws kub thiab tawg. Txhawm rau tiv thaiv cov teeb meem tsis zoo, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem kev nyab xeeb thiab cov lus qhia thiab kom paub tseeb tias cov cuab yeej siv tau zoo.
Hauv kev xaus, cov khoom siv distillation yog cov cuab yeej tseem ceeb rau cov kuab tshuaj rov qab hauv cov tshuaj lom neeg. Nws tuaj yeem txo cov khoom pov tseg thiab txuag nyiaj, ntawm lwm yam, tab sis nws kuj tuaj nrog kev pheej hmoo yog tias siv tsis raug. Txhawm rau kom tsis txhob muaj teeb meem, nws yog ib qho tseem ceeb uas yuav tsum siv cov cuab yeej tsim nyog rau lub hom phiaj thiab ua kom muaj kev nyab xeeb ua ntej.
