Tsis zoo siv
Qhov ntsuas kub kuaj tau siv los ntawm cov pa sib cais ua raws li txoj ntsiab cai ntawm cov roj distillation roj-kua sib npaug. Los ntawm txoj haujlwm uas nthuav tawm cov roj-kua sib luag nrog cov khoom siv sib xyaw ua ke, nws tsis ncaj qha rau cov khoom siv sib xyaw thiab cov kev teb ncaj qha rau cov txheej txheem tiag tiag. Tus txheej txheem no muaj txiaj ntsig zoo. Cov kev tswj hwm kev hloov pauv tau siv tuaj yeem ncaj qha thiab muaj txiaj ntsig zoo rau cov xwm txheej distillation, uas pab ua kom pom cov txheej txheem distillation, uas tau ua kom tiav thiab tua cov txheej txheem tswj. Nws yog txheej txheem kev tswj cov qauv nrog cov nqi thov dav. Daim ntawv no tsom xam cov cascade tswj cov txheej txheem ntawm distillation ntauwd kub kub ntawm cov pa sib cais.

Taw qhia rau yav tom qab thev naus laus zis ntawm chav sib cais ntawm cov pa sib cais
TusPAS AIR SEPOMATIONFeem ntau yog siv cov ntsiab lus sib txawv ntawm cov pa, nitrogen thiab cais cov pa, thiab qee qhov sib cais ntawm cov pa, nitrogen thiab argon hauv huab cua. Hom no yog hu ua cryogenic distillation. Lub ntsiab distillation ntauwd paub txog kev sib cais ntawm cov pa thiab nitrogen nyob saum huab cua, thiab tib lub sijhawm tsim cov khoom siv rawents rau cov khoom siv Argon rau cov khoom sib cav sib ceg. Cov khoom siv raw yuav raug thauj mus rau Argon distillation system kom tshem tawm cov pa thiab nitrogen hauv nws. Cov txheej txheem ntawm Argon Extraction tseem tuaj yeem lees txais Cryogenic Distillation.
Cov txheej txheem tseem ceeb ntawm chav sib cais ntawm cov pa sib cais yog qhov system distillation, thiab cov pej thuam distillation pej thuam yog cov khoom tseem ceeb yog cov khoom tseem ceeb. Hauv kev ua haujlwm, kev hloov pauv hauv cov qauv cua ntws thiab cov qauv tsim khoom yuav cuam tshuam rau cov txheej txheem distillation. Cov xwm txheej ua haujlwm ntawm lub ntsiab distillation pej thuam ntawm chav sib cais yog lub ntsiab tau cuam tshuam rau Argon distillation. Tsuas yog los ntawm kev ntseeg tau tias lub ntsiab distillation pej thuam yog nyob rau hauv cov txheej txheem kev ua haujlwm zoo tshaj plaws thiab cov haujlwm ua haujlwm ntawm tus neeg hais lus Crudenser yuav tsum ua kom zoo nkauj.
Kev sib cuam tshuam nruab nrab ntawm lub ntsiab distillation ntauwd thiab lub argon distillation ntauwd
Nyob rau hauv cov roj sib xyaw ntawm cov khoom siv raw ntawm lub argon distillation ntauwd, uas yuav tsis tsuas yog ua rau muaj kev sib cav sib ceg, tab sis kuj ua rau muaj kev sib txawv ntawm cov neeg sib txawv Distillation pej thuam yog tias cov neeg ua haujlwm tsis txaus ntseeg, cuam tshuam rau cov pa oxygen thiab nitrogen nyob rau hauv lub ntsiab distillation ntauwd, uas muaj qhov tsis zoo ntawm cov pa sib cais.
Lub zog tsis siv neeg ntawm qhov rhiab heev ntawm lub ntsiab distillation tower saws ntawm cov huab cua sib cais ntawm cov haujlwm distillation ntawm cov pa sib cais. Raws li cov khoom siv hauv cov khoom ntawm Argon distillation system, thaum cov nitrogen tivthaiv ntawm cov leeg sib txawv tshaj tus qauv, nws yuav ua rau muaj kev hloov pauv loj heev, uas yog hu ua "nitrogen plug". Tsuas yog los ntawm kev txhawb nqa cov distillation ntawm lub ntsiab distillation pej thuam tuaj yeem tshwm sim ntawm kev ua haujlwm tsis zoo ntawm "Nitrogen plugging" zam kev zam thiab cov nyhuv tiv thaiv tau ua si.
Kev Siv Txheej Txheem Tswjhwm Saib Xyuas Kev Tswj Xyuas
Cov txheej txheem kev siv tshwj xeeb yog:
Teeb cov txheej txheem cascade tswj cov voj voog los ntawm cov txheej txheem hluav taws xob uas yog cov txheej txheem kev tswj hwm tau zoo li cov txheej txheem kev tswj hwm ntawm cov txheej txheem ntsuas kub ntawm cov khoom ua haujlwm ua kua ntawm cov kua dej ua kua Nitrogen Extraction Outpaction Outpution Tso tawm los ntawm cov txheej txheem tseem ceeb ntawm cov khoom siv ua kua ntawm lub zog ntawm cov khoom siv ua kua dej
Tsim qauv ntawm cov txheej txheem tseem ceeb thiab cov txheej txheem tswj kev tswj hwm loops rau lub ntsiab distillation ntauwd variables
Qhov rhiab ntawm lub ntsiab distillation pej thuam yog txoj haujlwm uas cov concient hloov cov txheej txheem ntawm txhua cov pej thuam ntawm cov pej thuam distillation ntauwd. Qhov rhiab tshaj qhov kub yog qhov siab tshaj plaws ntawm cov kev hloov pauv, thiab nws cov kev sib raug zoo yog qhov kub ntauwd-kua sib npaug ntawm cov duab kos. Cov ntaub ntawv ntawm qhov kub ntawm lub siab rhiab ntawm lub ntsiab distillation ntauwd cov ntaub ntawv, thiab cov pid (sib xyaw ua ke ntawm cov txheej txheem tswj cov txheej txheem sab hauv DCS tuaj yeem siv. Lub ntsiab txheej txheem tswj lub voj yog txhais tau tias yog TIC1717, thiab cov khoom siv PID muaj kev tswj hwm yog cov khoom lag luam ntws tawm ntawm cov pej thuam sab saud. Raws li cov txiaj ntsig ntawm cov kua nitrogen khoom fic1630 muab cov khoom siv ntawm cov pid
Kev ntsuas los tiv thaiv kev lag ua loj thiab kev hloov kho ntau dua ntawm cov txheej txheem tswj
Kev ntsuas los tiv thaiv Lag loj:
Hloov cov ntaub ntawv ntsuas kub los ntawm kev tshawb pom qhov kawg ntawm TIC1717 tswj lub voj rau hauv thermodynamic kub
Teem lub amplification yam los txhim kho qhov rhiab ntawm cov ntaub ntawv nrhiav tau. Xaiv cov kua nitrogen tso tawm vim tias kev tswj hwm tau nce mus tau vim tias nws cuam tshuam rau reflux piv sai thiab zoo. Kev ntsuas kom tiv thaiv kev hloov kho dua tshiab:
Siv sijhawm tsawg rau cov zis ntawm lub ntsiab txheej txheem tswj lub voj tic1717
Programming cov tswj kev tswj cov zis ntau yam txwv tsis pub
Txhais cov qauv tsim muaj raws li cov kua nitrogen tso zis tawm ntawm cov cua sib cais khoom
