Raws li cov txheej txheem ntws, cov cuab yeej tuaj yeem muab faib ua rau rau pawg loj:
Cov khoom siv thauj khoom: suav nrog cov kav dej, twj, thiab compressors, lub luag haujlwm thauj cov khoom siv raw thiab cov khoom.
Cov khoom siv cua sov: Feem ntau tubular cua sov rauv, muab lub zog thermal xav tau rau cov roj crude tawg.
Cov cuab yeej siv hluav taws xob sib hloov: suav nrog cov khoom siv hluav taws xob rov qab thiab cov cua txias, siv los ua kom lub zog rov qab los.
Cov khoom siv tshuaj tiv thaiv: Catalytic cracking reactors thiab hydrogenation reactors ua haujlwm tseem ceeb.
Cov cuab yeej hloov khoom loj: Distillation yees thiab nqus cov yees ua cov haujlwm sib cais.
Cov khoom siv cia: suav nrog cov roj cia tso tsheb hlau luam thiab cov tso tsheb hlau luam tsis sib xws, ua kom muaj kev tsim khoom txuas ntxiv.
Tsis tas li ntawd, cov khoom siv roj refining tuaj yeem raug cais raws li lwm cov qauv. Raws li cov khoom noj khoom haus, pawg suav nrog cov khoom siv rau kev ua cov log tsheb khib nyiab, khib nyiab pov tseg, roj av sludge, thiab cov coal tar residue. Kev faib tawm los ntawm cov khoom siv ua haujlwm suav nrog cov khoom siv tshwj xeeb tsim los ua kom zoo dua cov reactor kev ua tau zoo, xws li siab - cov khoom siv hluav taws xob zoo (HD trays), ultra-flat quench trays (UFQ), thiab sab hauv rau cov kua dej catalytic cracking (FCC) units.
