Hauv kev lag luam petrochemical, muaj ntau hom khoom ua kua uas muaj cov tshuaj sib txawv. Cov khoom siv tshuaj lom neeg no raug thauj mus los siv cov tsheb sib txawv xws li tsheb thauj khoom, tsheb thauj khoom, lossis cov tsheb thauj khoom, thiab lawv txawv ntawm hom thiab qhov loj me. Tsis tas li ntawd, txoj kev thauj khoom thiab kev thauj khoom tuaj yeem sib txawv, suav nrog hom kev thauj khoom sab saum toj thiab hauv qab. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov tsim nyog ntawm kev thauj khoom caj npab raws li cov xwm txheej tshwj xeeb, vim qhov no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb hauv kev tsim khoom.
Dab tsi yog cov ntsiab cai ua raws thaum xaivloading caj npabrau loading thiab unloading?
1. Thaum tuav cov roj liquefied roj av los yog cov khoom siv roj liquefied, yuav tsum tau siv cov khoom ntim khoom kaw.
2. Rau cov ntaub ntawv uas muaj qhov saturated vapor siab nyob ze los yog siab tshaj 0.1 MPa (siab siab) nyob rau hauv ib txwm kub cia thiab loading tej yam kev mob, kaw loading caj npab yuav tsum tau siv.
3. Thaum soj ntsuam cov ntaub ntawv uas yog volatile kua, flammable, explosive, environmentally txaus ntshai, los yog ua phem rau tib neeg noj qab haus huv nyob rau hauv ib txwm kub cia thiab loading tej yam kev mob, kaw loading caj npab yuav tsum tau siv.
4. Rau cov ntaub ntawv uas yog volatile kua, thiab yog hais tias cov volatile gases muaj ib co recycling nqi, kaw loading caj npab yuav tsum tau siv.
5. Thaum unloading tankers los yog tankers siv roj pressurization los yog nqus extraction, kaw loading caj npab yuav tsum tau siv.
6. Txhawm rau tswj cov khoom siv corrosive thiab tiv thaiv cov khoom txaws los yog ua kom muaj kev nyab xeeb ntawm tus kheej, yuav tsum tau siv cov khoom ntim khoom kaw.
7. Rau kev thauj khoom thiab tshem tawm ntawm cov khoom siv hluav taws xob uas tsis tshua muaj hluav taws xob thiab tsis muaj kev phom sij, qhib lub caj npab tuaj yeem siv.
8. Rau cov ntaub ntawv uas tsis tshua muaj hluav taws xob thaum lub sij hawm thauj khoom, ib qho luv luv spout tuaj yeem siv tau, xws li lub qhov hluav taws xob 90 degree kab rov tav lossis 45 degree angled qhov hluav taws xob.
Peb yog cov chaw tsim khoom ntawm kev thauj khoom caj npab, peb tuaj yeem muab cov khoom thauj khoom sab saum toj, hauv qab caj npab, tshwj xeeb thauj caj npab, peb tuaj yeem tsim cov khoom thauj khoom raws li cov neeg siv khoom xav tau. Yog xav paub ntxiv txog kev thauj khoom caj npab, txais tos rautiv tauj peb.
