Roj cia tank: kev ua haujlwm, hom thiab cov qauv

Hauv kev lag luam refining,roj cia tanksNws yog ib qho tseem ceeb uas yuav tsum muaj cov khoom siv hluav taws xob ntau hauv cov khoom siv roj. Cov chav no ua kom muaj kev nyab xeeb hauv kev tsim khoom, kev thauj mus los, kev faib tawm, thiab khaws cia cov phiaj xwm hydrocarbons.

Lawv tsim, kev ua haujlwm, thiab kev saib xyuas yog tswj hwm los ntawm API cov qauv, ua kom muaj kev ncaj ncees, kev ua haujlwm nyab xeeb thiab kev ua raws li ib puag ncig. Tsab ntawv xov xwm no piav qhia txog lub luag haujlwm tseem ceeb, feem ntau siv hom tso tsheb hlau luam thiab cov kev cai API tank tam sim no, tsom rau cov kws tshaj lij thiab cov koom haum hauv lub zog thiab kev lag luam.

Hydrocarbon cia tankyog cov thawv ntim khoom tsim los kom ruaj ntseg khaws cov khoom xws li roj av, roj av, lossis roj diesel. Lawv yog cov cylindrical thiab ntsug, nrog ruaj lossis ntab ru tsev, thiab ua haujlwm ntawm atmospheric siab.

Lawv tau siv thoob plaws hauv lub zog saw hlau los tswj cov khoom lag luam tawm tswv yim, txhawb kev ua haujlwm ntawm refineries thiab xyuas kom cov khoom lag luam txuas ntxiv ntawm kev lag luam hauv tsev, thiab ua lub luag haujlwm tseem ceeb hauv cov chaw nres nkoj terminals, tshuaj nroj tsuag thiab lub teb chaws tis network.

Nyob ntawm lawv qhov chaw, lawv ua tiav cov haujlwm hauv qab no:

• Kev Txais: Lawv khaws cov roj av los ntawm qhov dej lossis cov chaw ua haujlwm.
• Intermediate: Ua raws li buffers ntawm cov txheej txheem.
• Dispatch: Tso cai hloov mus rau cov kav dej, nkoj, lossis cov nkoj thauj khoom.
• Kev sib xyaw: Qee lub tso tsheb hlau luam agitate cov ntsiab lus kom homogenize nws.
• Kev sib cais: Lawv pab decant dej thiab sediments los ntawm hydrocarbons.

Txhua qhov kev ua haujlwm ntawm lub tank tsim thiab yuav tsum ua raws li cov kev cai ntawm cov qauv xws li API 650. Tsis tas li ntawd, kev tsim kom muaj txiaj ntsig zoo tso cai rau kev ua haujlwm ruaj khov, txhim kho cov khoom lag luam tswj thiab txo cov evaporation poob.

Hydrocarbon cia yog qhov tseem ceeb hauv kev xa khoom hluav taws xob. Hauv cov roj av, cov tank me me, cov twj tso kua mis modular yog siv, thaum nyob rau hauv refineries thiab terminals, loj - ntim tank welded rau - site predominate.

Tsis tas li ntawd, nyob rau hauv cov chaw faib khoom hauv nroog, kev cog lus, faus lossis ntsug tso tsheb hlau luam yog siv, hloov kho kom txo tau qhov chaw thiab nrog kev ntsuas kev ntsuas thiab kev nyab xeeb.

Qhov tshwj xeeb ntawm cov roj crude

• High viscosity: Yuav tsum tau rwb thaiv tsev los yog cua sov tshuab.
• Muaj cov sediments: Yuav tsum tau decanting ua ntej refining.
• Corrosive compounds (hydrogen sulfide (H₂S), carbon dioxide (CO₂), naphthenic acids thiab chlorides: Xav tau cov ntaub ntawv nrog cov txheej tshwj xeeb.

Cov yam tseem ceeb no txiav txim siab cov qauv tsim muaj zog uas ua kom muaj kev ruaj ntseg, kev nyab xeeb thiab ua raws li kev xav tau ntawm lub tank ntau dua.

Raws li kev khiav hauj lwm siab

• Atmospheric: mus txog 1 psig. Txuj: API 650, API 12C.
• Tsis tshua muaj siab: mus txog 1.055 kg / cm². Txuj: API 620.
• Kev kub siab: rau cov kua dej volatile. Txuj: API 620, ASME.
• Txias: rau cov roj cua cryogenic. Txuj: API 625, ASME.

Raws li kev tsim qauv

• Vertical cylindrical: feem ntau siv nyob rau hauv refineries.
• Spherical: nyiam rau cov pa roj xws li LPG.
• Kab rov tav / mobile: nyob rau hauv ib ntus lossis thaj chaw teeb tsa.

Nyob ntawm kev tsim lub ru tsev

• Tsau lub ru tsev: rau cov khoom ruaj khov.
• Floating roof: minimizes evaporation losses (Daim duab 1).
• Geodesic dome: lub teeb, tiv taus, txhim kho atmospheric sealing.

Hom tanks raws li lawv cov kev txav mus los

• Nyob ruaj ruaj: tsau nyob rau hauv terminals los yog logistics chaw.
• Txawb: nkoj, tankers, tanker tsheb lossis tsheb thauj khoom.
• Xaiv hom zoo kuj yog nyob ntawm tus nqi ntawm kev teeb tsa, kev yooj yim ntawm kev txij nkawm thiab qib siab ntawm automation. Ib qho kev xaiv tsis zoo tuaj yeem ua rau cov nqi ua haujlwm dhau mus thiab tsis tsim nyog txaus ntshai hauv lub neej voj voog ntawm cov khoom siv.

Kev ua raws cai yog qhov tseem ceeb hauv kev tsim thiab kev ua haujlwm ntawm cov tso tsheb hlau luam. Qhov tseem ceeb tshaj plaws API tank qauv yog:

1. API 650: Welded steel atmospheric tanks: Tsim cov txheej txheem rau thicknesses, welds, kuaj thiab ntws. Nws yog dav siv nyob rau hauv refineries thiab faib terminals. Cov qauv no tseem suav nrog cua, seismic thiab hydrostatic siab loads, kom ntseeg tau ntev - lub sij hawm kev ncaj ncees.

2. API 620: Tsis tshua muaj siab tso tsheb hlau luam: Npog cov qauv tsim rau cov tso tsheb hlau luam nrog lub siab siab txog 15 psig. Nws kuj yog siv nyob rau hauv cryogenic tej yam kev mob nrog nickel hlau. Nws daim ntawv thov yog nquag nyob rau hauv LNG terminals thiab cov txheej txheem roj sib cais.

3. API 653: Kev tshuaj xyuas thiab kev saib xyuas: Cov qauv tseem ceeb rau cov tso tsheb hlau luam hauv kev pabcuam. Tswj kev kho, tshuaj xyuas, thiab kev tsim kho dua tshiab, ua kom nws cov qauv kev ncaj ncees. Nws kuj tseem siv tau thaum lub sijhawm ua haujlwm raug hloov kho lossis kev pabcuam lub neej ntawm lub tank uas twb muaj lawm txuas ntxiv.

4. Lwm cov qauv tseem ceeb: API 12: rau prefabricated modular tanks,NFPA 30: tiv thaiv hluav taws, ASME Seem VIII: siab hlab ntsha, ISO 28300 / API 2000: tswj siab thiab qhov cua.

Cov qauv no muab cov txheej txheem thev naus laus zis tseem ceeb kom tsis txhob muaj teeb meem kev ua haujlwm thiab ua raws li cov qauv thoob ntiaj teb. Lawv txoj kev ua raws cai yog saib xyuas los ntawm lub koom haum tswj hwm thiab kev tshuaj xyuas sab nraud.

Hydrocarbon cia tank yog siv nyob rau hauv ntau yam kev lag luam thiab logistics ib puag ncig.

• Nyob rau hauv refineries, khaws cov roj crude thiab refined khoom.
• Nyob rau hauv export terminals, rau xa los ntawm tankers.
• Hauv cov nroj tsuag tshuaj thiab petrochemical, ua ib feem ntawm cov txheej txheem tsim khoom.
• Hauv cov chaw pabcuam, nrog cov tank hauv av thiab kev tswj hwm.
• Nyob rau hauv tshav dav hlau, rau aviation fuels.

Txhua lub ntsiab lus ua haujlwm yuav tsum muaj kev tshuaj xyuas tshwj xeeb los txheeb xyuas hom tank, cov ntaub ntawv thiab cov cuab yeej tsim nyog. Nws tseem yog ib qho tseem ceeb rau kev pom yav tom ntej kev nthuav dav, kev hloov kho thev naus laus zis thiab kev hloov pauv rau kev hloov pauv hauv cov cai hauv zos lossis thoob ntiaj teb API tank.

Lub tswv yim tsim qauv yuav tsum xav txog kev nyab xeeb ntawm kev ua haujlwm, kev siv hluav taws xob zoo, kev kho kom zoo thiab kev tswj hwm ib puag ncig zoo, suav nrogcuam ​​tshuam ntawm kev tswj cov khoom pov tseg hauv cov tank ciathiab nws pov tseg kom raug. Cov ntsiab lus no yog lub hauv paus tseem ceeb rau kev ua haujlwm ruaj khov hauv kev ua raws li cov cai tam sim no.

Hydrocarbon cia tso tsheb hlau luam yog cov yam ntxwv ntawm lub zog system. Lawv xaiv, tsim, txij nkawm thiab digitalization, ua raws li cov qauv xws li API 650, API 620 thiab API 653, ua kom zoo rau kev tswj hwm kev khaws cia, ua kom muaj kev ua haujlwm txuas ntxiv, ua raws li cov cai tam sim no thiab txo cov kev pheej hmoo rau kev tsim kho vaj tse, ib puag ncig thiab kev ncaj ncees.
