Hauv kev lag luam roj av, lawv tsuas yog siv rau hauv kev tsim thiab ua cov roj av, roj av, thiab cov roj ntsha.
① Roj Crude muaj impurities, khoom txawv teb chaws, xuab zeb hais, thiab hais txog.Cov khoom siv lim dej no tuaj yeem tshem tawm tau zoo, ntxuav cov roj crude, thiab tiv thaiv kev puas tsuaj rau cov khoom siv refining tom ntej.
② Hauv cov txheej txheem ua kom zoo, cov khoom siv lim dej tuaj yeem siv los ntxuav cov ntaub ntawv raw, tiv thaiv impurities thiab stains hauv cov ntaub ntawv raw los ntawm kev ua rau hnav thiab xeb rau cov khoom siv tom ntej, tshem tawm cov deposits, impurities, thiab catalyst suspensions hauv catalytic thiab non-catalytic refining units. , thiab txhim kho cov refining efficiency thiab cov khoom zoo.
③Natural gas thiab liquefied gas muaj roj-dej sib tov, impurities, dej cov ntsiab lus, acid tshuaj, thiab lwm yam. Lim cov khoom siv los tiv thaiv corrosion, scaling, thiab blockages nyob rau hauv pipelines, li qub, thiab compressors, kom lub dryness thiab purity ntawm natural gas thiab roj liquefied, tiv thaiv cov cuab yeej los ntawm corrosion, thiab txhim kho lawv cov efficiency thiab kev nyab xeeb.
