Propylene yog ib hom olefin nrog cov qauv molecular ntawm C3H6. Nws yog xim tsis muaj xim thiab pob tshab, nrog qhov ceev ntawm 0.5486 g / cm3. propylene feem ntau yog siv rau hauv kev tsim cov polypropylene, polyester, glycol, butanol, thiab lwm yam, thiab yog ib qho tseem ceeb raw cov ntaub ntawv hauv kev lag luam tshuaj. Tsis tas li ntawd, propylene kuj tseem siv tau los ua ib lub tshuab nqus tsev, lub tshuab tshuab thiab lwm yam kev siv.

Propylene feem ntau yog tsim los ntawm refining roj feem. Cov roj crude yog muab cais ua feem nyob rau hauv lub distillation ntauwd, thiab ces cov feem ntau refined nyob rau hauv lub catalytic cracking unit kom tau propylene. Propylene yog sib cais los ntawm cov tshuaj tiv thaiv roj nyob rau hauv lub catalytic cracking unit los ntawm ib txheej ntawm cais kab thiab purification kab, thiab ces muab cia rau hauv lub tank cia rau siv ntxiv.

propylene feem ntau yog muag nyob rau hauv daim ntawv ntawm tej los yog lub tog raj kheej roj. Rau kev muag khoom ntau, propylene yog thauj mus rau cov neeg siv khoom cog los ntawm lub tanker lossis cov kav dej. Cov neeg siv khoom yuav siv propylene ncaj qha rau hauv lawv cov txheej txheem tsim khoom. Rau lub tog raj kheej roj muag, propylene tau ntim rau hauv lub tog raj kheej siab thiab thauj mus rau cov neeg siv khoom cog. Cov neeg siv khoom yuav siv propylene los ntawm kev txuas lub tog raj kheej rau cov khoom siv nrog lub hose.

Tus nqi ntawm propylene yog cuam tshuam los ntawm ntau yam, suav nrog cov nqi roj av, cov khoom siv thiab kev xav tau ntawm propylene kev ua lag luam, tus nqi pauv, thiab lwm yam. Feem ntau, tus nqi ntawm propylene yog tus nqi siab, thiab nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev ua lag luam txhua lub sijhawm. lub sijhawm thaum yuav khoom propylene.

Hauv cov ntsiab lus, propylene yog ib qho tseem ceeb raw khoom hauv kev lag luam tshuaj, uas yog tsim los ntawm refining roj feem thiab siv nyob rau hauv zus tau tej cov polypropylene, polyester, glycol, butanol, thiab lwm yam. Tus nqi ntawm propylene yog cuam tshuam los ntawm ntau yam, thiab nws. Nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev ua lag luam txhua lub sijhawm thaum yuav khoom propylene.
