Ib tug loj tus naj npawb ntawm cov khoom siv tshuaj niaj hnub no yog tsim los ntawm cov tshuaj tiv thaiv nyob rau hauv cov tshuaj reactors.
Cov tshuaj reactor, nyob rau hauv qhov tseeb, yog ib tug loj -scale kaw cov tshuaj tiv thaiv nkoj: raw cov ntaub ntawv yog pub rau hauv nws, thiab los ntawm kev tswj tej yam kev mob xws li kub thiab siab, cov txheej txheem xws li synthesis, polymerization, thiab cracking yog ua tiav kom tiav cov khoom lag luam.
Hauv kev tsim tshuaj lom neeg, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm ntawm cov reactors thiab tswj cov khoom zoo yog qhov tseem ceeb tshaj plaws - thiab daim ntawv thov nitrogen yog qhov kev ntsuas tseem ceeb los tiv thaiv ob qho tib si.
Feem ntau, ua ntej pib cov tshuaj tiv thaiv, nitrogen yog siv los ua kom tag nrho cov huab cua (feem ntau oxygen) hauv lub reactor; Hauv qee cov txheej txheem, nitrogen tseem txuas ntxiv mus rau hauv lub reactor thaum lub sijhawm ua haujlwm kom tswj tau qhov chaw tsis muaj zog.
Nitrogen yog ib qho roj inert nrog cov tshuaj ruaj khov, thiab nws tsis tshua muaj kev cuam tshuam nrog cov khoom siv tshuaj lom neeg feem ntau lossis cov khoom nruab nrab. Kev siv cov nitrogen hauv reactors pab ob lub hom phiaj tseem ceeb: ua ntej, nws txo qis qhov tsis zoo ntawm cov pa oxygen. Rau oxidizable raw cov ntaub ntawv (xws li tej yam organic intermediates los yog hlau catalysts), oxygen ua rau sab kev xav uas txo cov khoom purity, degrade xim, los yog txawm tsim tshuaj lom thiab teeb meem oxidation byproducts. Nyob rau hauv siab -exothermic cov tshuaj tiv thaiv (xws li, hydrogenation cov tshuaj tiv thaiv, olefin polymerization), oxygen tov nrog cov tshuaj tiv thaiv kab mob tuaj yeem tsim cov roj sib tov sib xyaw; Yog tias raug kub hnyiab hauv zos lossis hluav taws xob zoo li qub, qhov no tuaj yeem yooj yim ua rau muaj kev nyab xeeb xwm txheej xws li tawg lossis deflagrations. Tsis tas li ntawd, thaum lub sij hawm hloov cov khoom siv tom qab cov tshuaj tiv thaiv, nruam nitrogen purging tiv thaiv huab cua rov qab, tsis txhob oxidation paug ntawm cov khoom tiav thaum tawm. Los ntawm qhov kev xav ntawm cov txheej txheem kev lag luam thiab kev ua tau zoo, kev hloov pauv nitrogen yog tus nqi - cov kev daws teeb meem zoo uas sib npaug kev nyab xeeb thiab kev ua tau zoo, deb tshaj qhov ua tau zoo tshaj - nqi siv ntawm lwm cov roj inert (xws li argon).
Txawm li cas los xij, ib txwm siv cov khoom siv nitrogen (piv txwv li, lub raj mis nitrogen, kua nitrogen) muaj kev txwv tseem ceeb hauv kev tsim tshuaj: lub raj mis nitrogen muaj peev xwm tsawg; rau kev ua haujlwm tsis tu ncua reactor cov kab ntau lawm, yuav tsum tau hloov lub tog raj kheej tsis tu ncua, uas tsis yog tsuas yog nce nqi zog tab sis kuj muaj kev pheej hmoo qhia huab cua thaum lub tog raj kheej hloov, ua rau cov txheej txheem hloov pauv. Thaum cov kua nitrogen tuaj yeem muab cov khoom ntim loj, nws yuav tsum tau muab tso rau hauv lub tank cryogenic thiab ua rau muaj kev puas tsuaj (feem ntau 2% -5% txhua hnub); Cov nqi tsheb thauj mus los kuj tseem nce siab nrog kev ncua deb, ua rau tag nrho cov nqi siab rau me me thiab nruab nrab -cov tuam txhab tshuaj lom neeg lossis cov nroj tsuag hauv thaj chaw deb.
Rau cov laj thawj no, equipping chemical reactors nrog aPSA nitrogen generatortau dhau los ua qhov kev xaiv zoo tshaj. APSA nitrogen generatorsiv cov cua inexhaustible raws li nws cov khoom siv raw, nrog carbon molecular sieve li adsorbent. Raws li lub siab viav vias adsorption (PSA), nws cais cov pa oxygen thiab nitrogen los ntawm leveraging cov pa roj carbon molecular sieve xaiv adsorption ntawm ob gases. Piv nrog rau cov txheej txheem tsim cov tshuaj nitrogen ib txwm muaj, nws qhov zoo yog qhov tsim nyog rau cov khoom siv tshuaj lom neeg: Nws muaj cov txheej txheem yooj yim ntws, tsis tas yuav tsum muaj cov cuab yeej ua ntej; nws cov qib siab ntawm automation tso cai rau nws txuas nrog lub reactor DCS tswj qhov system, hloov kho nitrogen tso tawm raws li cov ntaub ntawv xws li reactor siab thiab cov ntsiab lus oxygen; nws muaj cov roj av ceev ceev, ncav cuag purity 15-30 feeb tom qab pib ua haujlwm, ua kom cov lus teb sai sai rau cov kev xav tau ntawm lub reactor ib ntus; lub zog noj tsuas yog concentrated nyob rau hauv cov huab cua compression theem, nrog rau kev khiav hauj lwm nqi txog 1/3 mus rau 1/2 ntawm lub raj mis nitrogen; nws yog nruab nrog ib tug online nitrogen purity detector rau tiag -lub sij hawm soj ntsuam cov roj zoo, tsis txhob cuam tshuam cov txheej txheem vim tsis txaus purity; thiab nws yog ib qho yooj yim rau kev khiav lag luam thiab tswj, tsuas yog yuav tsum tau hloov cov lim dej tsis tu ncua thiab kev soj ntsuam ntauwd adsorption, txhawb kev ua haujlwm tsis tu ncua.
Rau cov lag luam chemical, aPSA nitrogen generatoryog ib qho - lub sij hawm peev uas muab ntev - lub sij hawm ruaj khov gas mov: nws tshem tawm cov hassle ntawm lub tog raj kheej tuav thiab kua nitrogen procurement, thaum tsis tu ncua thiab stably muab kev tiv thaiv inert rau reactors, txo tus nqi tag nrho cov khoom nyob rau hauv lub sij hawm ntev.
