Cov pa roj rov qab system yog ib qho cuab yeej tiv thaiv ib puag ncig txhawm rau txo cov pa phem uas tsim tawm hauv kev tsim khoom thiab lwm yam dej num. Los ntawm kev rov ua kom rov zoo thiab kho cov pa pa tawm, nws tsis tsuas yog tiv thaiv ib puag ncig tab sis kuj ua tiav cov peev txheej rov qab siv dua. Cov txheej txheem no tseem ceeb tshwj xeeb hauv kev lag luam xws li tshuaj lom neeg, roj av refining, tshuaj, thiab kev ua zaub mov, vim lawv pab cov tuam txhab ua tau raws li cov qauv ib puag ncig thaum txhim kho lub zog thiab cov khoom siv. Cov hauv qab no yog 500 lo lus kab lus hais txog cov pa roj rov ua haujlwm:

Hauv cov txheej txheem kev lag luam niaj hnub no, cov pa tawm emissions yog ib qho teeb meem uas yuav tsum tau zam. Cov pa hluav taws xob no tsis tsuas yog muaj cov khoom tsis zoo uas ua rau muaj kuab paug rau ib puag ncig, tab sis kuj tseem tuaj yeem muaj cov tshuaj siv rov ua dua tshiab thiab lub zog, thiab lawv cov emissions ncaj qha tsis yog tsuas yog pov tseg cov peev txheej xwb tab sis kuj ua rau kev puas tsuaj rau ecology. Yog li ntawd, cov pa roj rov qab system tau dhau los ua ib txoj hauv kev zoo los daws qhov teeb meem no. Los ntawm kev sau, ua kom huv, thiab rov ua dua cov pa roj carbon monoxide, kev ua qias tuaj ib puag ncig tuaj yeem raug txo thiab kev siv cov peev txheej tuaj yeem txhim kho, uas yog ib qho tseem ceeb rau kev ua tiav kev tsim kho kev lag luam.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov pa roj rov qab feem ntau suav nrog ntau cov kauj ruam tseem ceeb: sau cov pa roj, kev kho thiab ntxuav cov pa tawm, thiab rov ua dua thiab siv. Ua ntej, cov khoom siv hluav taws xob tsim hluav taws xob tau sau los ntawm kev sib sau ua ke, thiab tom qab ntawd los ntawm kev kho thiab kev ua kom huv huv, cov khoom tsis zoo hauv cov pa tawm raug tshem tawm, thiab cov tshuaj muaj txiaj ntsig lossis lub zog rov qab los. Thaum kawg, cov roj ua tiav yuav tsum tau muab pov tseg kom zoo lossis rov ua dua tshiab.

Daim ntawv thov teb ntawm cov pa roj rov qab yog qhov dav, thiab cov kev lag luam sib txawv thiab cov txheej txheem tsim khoom yuav tsum tau siv cov cuab yeej rov qab sib txawv. Piv txwv li, hauv kev lag luam petrochemical, cov kuab tshuaj organic thiab cov tshuaj hydrocarbon hauv cov pa roj tuaj yeem rov qab los ntawm txoj kev xws li nqus, adsorption, thiab condensation; Nyob rau hauv kev tsim hluav taws xob thiab thermal zog, emission ntawm sulfur dioxide thiab nitrogen oxides yuav raug txo los ntawm flue gas desulfurization thiab denitrification technology; Hauv kev ua zaub mov thiab kev lag luam tshuaj, organic vapors thiab cawv los ntawm cov pa roj tuaj yeem rov qab los siv rau hauv lwm cov txheej txheem tsim khoom.

Cov pa roj rov qab system tsis tsuas yog pab cov lag luam txo cov nqi khiav lag luam thiab txhim kho kev lag luam, tab sis kuj ua lub luag haujlwm zoo hauv kev tiv thaiv ib puag ncig. Txo cov emission ntawm cov pa phem thiab txo cov pa phem rau huab cua thiab lub ntiaj teb ib puag ncig tuaj yeem pab txhim kho huab cua zoo thiab tiv thaiv tib neeg kev noj qab haus huv. Nyob rau tib lub sijhawm, kev txhim kho thiab siv cov pa roj rov qab thev naus laus zis kuj tau txhawb nqa kev nce qib ntawm kev tiv thaiv ib puag ncig thiab kev tsim kho tshiab hauv kev tswj hwm ib puag ncig.

Nyob rau hauv luv luv, cov pa roj rov qab systems yog cov cuab yeej tseem ceeb rau kev ua tiav ib puag ncig tus phooj ywg kev lag luam ntau lawm thiab kev siv tau zoo. Nrog rau kev tswj hwm ib puag ncig nruj zuj zus thiab kev txhim kho ntawm pej xeem ib puag ncig kev paub, cov pa roj rov qab siv tshuab yuav siv dav thiab tsim kho, dhau los ua qhov tseem ceeb ntawm kev txhawb nqa kev siv cov tswv yim txhim kho kom ruaj khov.
