Hauv kev lag luam tshuaj, tshuaj chemical ua haujlwm ib lub luag haujlwm tseem ceeb. Nws yog cov khoom siv txhua yam uas tuaj yeem hloov kho ntau yam kev ua haujlwm nyuaj thiab tau raws li cov kev xav tau dej thauj khoom hauv cov txheej txheem kev siv tshuaj.
Tshuaj lom neeg cov twj tshuaj lom tau siv dav. Hauv kev lag luam petrochemical, nws yog siv los thauj ntau yam dej xws li roj nyoos, cov roj ua kom zoo nkauj, thiab roj. Txawm hais tias nws yog cov roj thauj roj hauv cov roj tawm lossis cov roj ntsha siv hluav taws xob, cov twj siv tshuaj ntxhua khaub ncaws kom ntseeg tau tias cov txheej txheem kev txhim kho ntawm cov txheej txheem ntau lawm.
Hauv kev ua haujlwm ntawm cov tshuaj zoo, kev siv tshuaj chemical kuj tseem tsis tau kuaj. Cov tshuaj lom neeg raug tshuaj tau muaj heev heev rau qhov raug thiab huv cov ntaub ntawv. Tshuaj lom neeg muaj tshuaj lom neeg tuaj yeem tswj tau qhov kev ntws thiab siab ntawm cov kua kom ntseeg tau tias cov txheej txheem ntau lawm ntawm cov khoom lag luam zoo. Piv txwv li, thaum tsim cov tshuaj lom neeg siab huv, qhov ntsuas kev ua haujlwm siab ntawm cov tshuaj lom neeg tuaj yeem tiv thaiv cov khoom sib kis thiab xau.
Ib qho ntxiv, cov pa kua kuj muaj cov ntawv thov tseem ceeb hauv kev tiv thaiv ib puag ncig. Hauv kev tiv thaiv ib puag ncig xws li kev kho dej phwj tuaj thiab cov roj ntsha tau xws li cov kav dej huv thiab khib nyiab mus kho cov cuab yeej siv.
Nrog kev nce qib nruam ntawm kev tshawb fawb thiab thev naus laus zis, kev ua tau zoo thiab cov twj tshuaj lom tau zoo ib txwm txhim kho. Daim ntawv thov ntawm cov ntaub ntawv tshiab, kev saws kev tsim khoom tshiab thiab cov lus qhia ntawm cov ntse tswj cov thev naus laus zis, kev txuag hluav taws xob ntau thiab txuag cov twj tso kua mis.
Hauv cov tshuaj sib txawv tsim khoom, cov twj tshuaj chemical tau qhia lawv cov txiaj ntsig tshwj xeeb. Nws cov haujlwm ruaj khov ua kom muaj kev ua haujlwm tau zoo thiab kev nyab xeeb ntawm cov tshuaj lom neeg siv tshuaj thiab muab kev txhawb nqa rau kev txhim kho kev lag luam tshuaj. Yav tom ntej, nrog kev txhim kho kev lag luam txuas ntxiv ntawm kev lag luam tshuaj, kev thov cov kev cia siab ntawm cov twj tshuaj lom neeg yuav nthuav dav.
