Kev txiav txim siab txog kev tsim qauv, cov ntaub ntawv sib npaug ntawm cov khoom siv, kev sib koom ua ke hauv qab, thiab cov kev xav tau kev nyab xeeb rau me me - nplai captive chlor-alkali chaw.
5 TPD NaOH Nroj Tsuag Yuav Tsum Muaj Cov Txheej Txheem Kev Tsim Kho
A 5 TPD NaOH- sib npaug daim nyias nyias chlor-alkali tsob nroj yog ib qho me me - cov tshuaj tsim tawm, tab sis nws cov qauv tsim engineering muaj ntau tshaj li qhov tsuas yog xaiv cov electrolyzer uas muaj peev xwm tsim tau 5 tonnes ntawm caustic soda ib hnub. Membrane electrolysis ua rau peb lub hauv paus ntws ib txhij: sodium hydroxide, chlorine thiab hydrogen. Yog li ntawd, cov nroj tsuag yuav tsum tau tsim nyob ib ncig ntawm tag nrho cov khoom sib npaug ntawm cov khoom no. Rau cov neeg raug ntes -chaw noj khoom haus, NaOH tuaj yeem muab ncaj qha mus rau cov txheej txheem qis qis, thaum cov tshuaj chlorine thiab hydrogen tuaj yeem hloov mus rau hydrochloric acid thiab sodium hypochlorite raws li qhov chaw siv tiag tiag.
Basic Electrochemical Reaction:2NaCl + 2H₂O → 2NaOH + Cl₂ + H₂
Cov khoom sib npaug txiav txim siab chlorine & Hydrogen Capacity
Siv cov theoretical stoichiometric kev sib raug zoo, ua 5 tonnes ntawm 100% NaOH sib npaug ib hnub sib raug rau kwv yees li 4.43 tonnes ntawm chlorine thiab 0.126 tonnes ntawm hydrogen ib hnub twg. Cov ntaub ntawv tsim tawm tiag tiag yuav txawv nyob ntawm qhov ua tau zoo tam sim no, lub zog hluav taws xob ntawm tes, kev ua haujlwm, kev ua haujlwm ntawm daim nyias nyias thiab cov txheej txheem poob. Qhov kev sib raug zoo no yog qhov tseem ceeb thaum sizing HCl synthesis thiab sodium hypochlorite seem vim tias cov khoom siv qis qis yuav tsum muaj peev xwm tsis tu ncua siv cov tshuaj chlorine uas tsim los ntawm electrolyzers.
Ua ntej xaiv cov khoom siv, tus neeg yuav khoom yuav tsum qhia meej meej seb puas tau hais 5 TPD lub peev xwm hais txog 100% NaOH sib npaug, ib qho kev daws teeb meem NaOH tshwj xeeb, lossis lwm lub hauv paus tsim khoom.
Membrane Electrolysis yog Lub Chaw Tsim Khoom
Lub membrane electrolysis hloov purified brine rau hauv caustic soda, chlorine thiab hydrogen. Cov txheej txheem ib txwm muaj xws li kev npaj brine thiab purification, purified brine ncig, daim nyias nyias electrolyzers, DC rectifiers, roj- cov khoom sib cais kua, caustic ncig thiab cov txheej txheem ntsuas. Lub ion- pauv daim nyias nyias cais cov anode thiab cathode compartments thaum tso cai rau xaiv ions hla los ntawm daim nyias nyias.
Cov Lus Cim Tseem Ceeb:Kev tuav cov brine kom zoo yog qhov tseem ceeb tshwj xeeb vim tias calcium, magnesium thiab lwm yam impurities tuaj yeem cuam tshuam rau kev ua haujlwm ntawm daim nyias nyias thiab ua kom cov kev tu ncua. Yog li ntawd, seem brine purification yuav tsum raug suav hais tias yog ib feem tseem ceeb ntawm cov tshuaj chlor-alkali nroj tsuag es tsis yog ib qho kev pabcuam kev pabcuam.
Zero -Zero Chlorine Cia Hloov Cov Nroj Tsuag Configuration
Qhov yuav tsum tau rau qhov tseem ceeb xoom chlorine cia muaj feem cuam tshuam rau tag nrho cov txheej txheem. Hloov chaw tsim cov tshuaj chlorine rau ntev - lub sij hawm cia thiab tom qab kev thauj mus los, cov tshuaj chlorine uas tsim los ntawm electrolyzer yuav tsum tsis tu ncua mus rau cov ntsiab lus ntawm cov dej ntws. Hauv qhov kev teeb tsa no, cov nroj tsuag tuaj yeem siv cov tshuaj chlorine rau HCl synthesis thiab sodium hypochlorite ntau lawm thaum txo cov khoom siv tshuaj chlorine tsawg.
Kev tsim qauv tsim qauv tsim qauv tseem yuav tsum tau txwv cov txheej txheem tuav- nce ntim, cov cuab yeej tswj kev siab thiab muaj peev xwm kho thaum muaj xwm txheej ceev, tab sis lub kaw lus tsis nyob ntawm qhov loj - teev cov tshuaj chlorine. Txoj hauv kev no yuav tsum muaj kev sib koom tes zoo ntawm lub peev xwm electrolyzer thiab qhov xav tau tshuaj chlorine tam sim ntawd ntawm cov dej hauv qab.
HCl Synthesis siv chlorine thiab hydrogen
Hydrochloric acid synthesis muab ib txoj hauv kev tseem ceeb rau kev siv los ntawm -cov khoom ntawm membrane electrolysis. Hydrogen thiab chlorine tsim los ntawm electrolyzer tuaj yeem ua ke raws li cov tshuaj tiv thaivCl₂ + H₂ → 2HCl, ua raws li kev nqus dej kom tau txais hydrochloric acid ntawm qhov xav tau concentration.
Los ntawm kev pom kev cog qoob loo, qhov kev npaj no yog qhov txaus nyiam vim tias ob qho tib si chlorine thiab hydrogen tuaj yeem siv es tsis txhob raug kho raws li cov dej khib nyiab cais. Txawm li cas los xij, HCl ntau lawm muaj peev xwm, lub hom phiaj acid concentration, kev khiav hauj lwm tej yam kev mob thiab downstream noj npaum li cas yuav tsum tau txhais ua ntej xaiv cov HCl synthesis, nqus, txias thiab cov khoom siv.
Sodium Hypochlorite Muab Txoj Kev Siv Chlorine Thib Ob
Sodium hypochlorite ntau lawm muaj lwm txoj kev siv tshuaj chlorine ncaj qha ntawm qhov chaw tsim khoom. Chlorine reacts nrog dilute sodium hydroxide los ua sodium hypochlorite, sodium chloride thiab dej. Vim tias cov txheej txheem chlor-alkali twb tsim NaOH, ib feem ntawm cov kwj deg tuaj yeem muab faib rau NaOCl seem raws li cov khoom lag luam xav tau.
Qhov tsim ntawm chav tsev no nyob ntawm qhov xav tau ntawm NaOCl muaj peev xwm, muaj -chlorine concentration, NaOH concentration, tshuaj tiv thaiv kub, qhov yuav tsum tau ua kom txias thiab lub sijhawm cia khoom. Cov kev txwv no yuav tsum tau teev tseg nyias es tsis xav tias NaOCl muaj peev xwm txiav txim siab los ntawm 5 TPD NaOH daim duab.
Integrated Material Balance txuas rau tag nrho cov nroj tsuag
Kev tsim cov txheej txheem tsim nyog tuaj yeem txhim kho nyob ib puag ncig cov khoom siv tas mus li: purified brine nkag mus rau hauv daim nyias nyias electrolyzers, NaOH raug xa mus rau kev noj qab haus huv los yog ntxiv concentration, hydrogen raug coj mus rau HCl synthesis, thiab cov tshuaj chlorine faib ntawm HCl synthesis thiab sodium hypochlorite ntau lawm.
Kev faib cov tshuaj chlorine yuav tsum yog raws li qhov xav tau tiag tiag rau HCl thiab NaOCl es tsis yog tsuas yog ua kom cov khoom lag luam ntau tshaj plaws. Cov txheej txheem tswj cov txheej txheem yuav tsum tau koom tes nrog cov electrolyzer thiab downstream units kom qhov kev hloov pauv hauv HCl lossis NaOCl xav tau tsis tsim kom muaj cov tshuaj chlorine tsis tuaj yeem.
chlorine kev nyab xeeb yuav tsum muaj nyob rau hauv cov qauv tsim
Ib qho ze -zero chlorine- lub tswv yim khaws cia tsis tau txhais hais tias cov khoom siv tshuaj chlorine tuaj yeem raug tshem tawm. Cov roj chlorine tseem yuav muaj nyob hauv cov txheej txheem piping, cov khoom sib cais thiab cov khoom siv qis qis thaum lub sijhawm ua haujlwm. Yog li ntawd, cov nroj tsuag yuav tsum xav txog kev tshawb nrhiav tshuaj chlorine, tswj cov roj routing, tswj kev ceev, kaw thaum muaj xwm ceev, qhov cua thiab thaum muaj xwm ceev chlorine nqus los yog txhuam.
Cov txheej txheem xwm txheej ceev yuav tsum tau tsim nyob ib puag ncig kev ua haujlwm thiab kaw qhov xwm txheej, suav nrog cov khoom siv qis qis thiab poob ntawm kev noj tshuaj chlorine. Lub hom phiaj yog txhawm rau tiv thaiv kev cuam tshuam hauv ib chav nyob hauv qab los ntawm kev tsim kom muaj qhov tsis zoo nyob hauv ntu electrolysis.
Cov Lus Qhia Txog Kev Muag Khoom yuav tsum txhais cov cog kom tiav
Ua ntej npaj cov lus hais, tus neeg yuav khoom yuav tsum muab qhov xav tau ntawm NaOH concentration, HCl ntau lawm muaj peev xwm thiab concentration, sodium hypochlorite muaj peev xwm thiab muaj -chlorine concentration, sijhawm ua haujlwm, sijhawm ua haujlwm txhua xyoo, ntsev zoo, dej zoo, hluav taws xob, khoom siv hluav taws xob, qhov chaw thiab cov qauv kev noj qab haus huv.
Cov kev txwv no cuam tshuam rau qhov loj ntawm cov electrolyzers, brine purification system, DC rectifier, cov khoom sib cais roj, HCl synthesis unit, NaOCl reactor, cua txias system, cov khoom tso tsheb hlau luam thiab kev nyab xeeb.
