Khoom Description
Lub tshuab tshem tawm cov roj hydrogen sulfide (tseem hu ua H₂S purification unit) yog cov cuab yeej siv dav dav ua ke ua ke ua ntej, ua kom huv, thiab tom qab- kho.
Nws cov ntsiab lus tseem ceeb sib txawv ntawm txoj kev siv tshuab: kev nqus tshuaj lom neeg siv cov tshuaj alkaline (xws li sodium hydroxide, amine) los ua H₂S; Lub cev adsorption cia siab rau cov adsorbents (xws li, cov pa roj carbon activated, molecular sieves) los cuab H₂S; Kev tshem tawm cov roj ntsha siv cov kab mob oxidize H₂S rau hauv cov khoom tsis zoo.
Nws tuaj yeem tswj hwm H₂S cov ntsiab lus hauv cov roj kho kom ua tau raws li lub teb chaws cov qauv (xws li GB 18918 rau cov dej khib nyiab tawm- roj, GB 17820 rau cov nkev) thiab yog qhov tseem ceeb lav rau kev nyab xeeb kev lag luam thiab kev tiv thaiv ib puag ncig.
Txoj cai ua haujlwm
Cov txheej txheem ua haujlwm ntawm Hydrogen Sulfide Tshem Tawm (noj lub ntsiab "pretreatment + chemical absorption + post-treatment" txoj hauv kev ua piv txwv) tuaj yeem ua tiav raws li tsib kauj ruam tseem ceeb: roj pretreatment → tshuaj nqus dej → kev siv tshuaj → siv tshuaj kho → purified gas output
Gas pretreatment:H₂S- muaj roj ua ntej nkag mus rau hauv lub nruas knockout thiab lim kom tshem tawm cov tee dej (dej, roj) thiab cov khoom siv (dej, impurities) nrog particle loj dua los yog sib npaug li 5 μm. Qhov no tiv thaiv kev thaiv ntawm qhov nqus tsev / cov kav dej thiab tsis txhob txo cov kev ua haujlwm ntawm absorbents / kev daws teeb meem.
Chemical absorption:Pretreated gas ntws mus rau hauv qab ntawm lub absorption pej thuam, thaum ib tug 5-15% alkaline absorbent (xws li, sodium hydroxide tov rau qis-CO₂ roj, MDEA amine tov rau high-CO₂ roj) yog sprayed downwards. Nyob rau hauv lub txaj ntim khoom (sau nrog cov txheej txheem ntim zoo li lub nplhaib nplhaib), roj thiab kua ua tiav kev sib cuag: H₂S reacts nrog cov absorbent (piv txwv li, H₂S + 2NaOH → Na₂S + 2H₂O) los ua cov ntsev ntsev, uas yog nqa mus rau hauv lub pej thuam hauv qab los ntawm kev daws.
Kev daws teeb meem:Cov tshuaj absorbent tom qab absorbing H₂S yog sau rau hauv lub pej thuam hauv qab sump, ces pumped mus rau ib lub tshav kub exchanger kom txias (tswj kub ntawm 30-40℃kom tswj tau qhov nqus efficiency), thiab thaum kawg recycled rov qab mus rau sab saum toj ntawm lub pej thuam. Ib feem me me ntawm "siv tov" (nrog txo alkali concentration) yog txuas ntxiv tawm kom tsis txhob muaj ntsev ntau ntxiv.
Kev siv tshuaj kho mob:Cov tshuaj tso tawm (muaj sodium sulfide / ammonium sulfide) raug xa mus rau lub tank nruab nrab, qhov uas nws tau kho nrog oxidants (xws li hydrogen peroxide) los hloov cov sulfides rau hauv tsis muaj leej faj lossis sulfate, ces tso tawm tom qab ua tiav cov qauv dej khib nyiab. Rau cov tshuab loj - nplai, cov tshuaj tuaj yeem rov tsim dua tshiab (piv txwv li, amine tov stripping) kom rov siv cov nqus dej.
Purified gas tso zis:Lub H₂S- tshem tawm cov pa tawm ntawm sab saum toj ntawm lub tshuab nqus tsev, dhau los ntawm kev tshem tawm cov pos huab kom tshem tawm cov dej ntws tawm (cov dej seem seem), thiab tom qab ntawd thauj mus rau cov txheej txheem hauv qab dej (xws li, cov kav dej nkev, cov kab hluav taws xob sib txuas) lossis tawm tom qab ua tau raws li cov txheej txheem ib puag ncig.
Hydrogen Sulfide Gas Tshem Tawm System Core Nta
High tshem tawm efficiency
Raws li tus qauv teeb tsa, H₂S tshem tawm kev ua haujlwm zoo dua lossis sib npaug li 98%; nrog rau kev tsim kho (xws li, ntau-theem nqus, siab- ua haujlwm adsorbents), nws tuaj yeem ncav cuag 99.9%, txo H₂S concentration ntawm 10,000 ppm mus rau qis dua 1 ppm.
Kev siv dav dav
Muaj peev xwm tswj tau cov roj ntws nrog H₂S concentration xws li 50 ppm txog 50,000 ppm, thiab hloov mus rau cov khoom siv roj sib txawv (xws li, nrog / tsis muaj CO₂, hydrocarbons) los ntawm kev hloov absorbents / adsorbents.
Kev ua haujlwm ruaj khov
Nruab nrog kev tswj tsis siv neeg (pH meters, H₂S online analyzers, flow controllers) los saib xyuas qhov tseem ceeb ntawm lub sijhawm; Thaum inlet H₂S concentration fluctuates, lub kaw lus kho absorbent npaum li cas / ntws tus nqi li ntawm 15-30 feeb kom muaj kev ruaj ntseg.
Corrosion kuj
Cov khoom tseem ceeb (nqus ntauwd, kav dej, twj tso kua mis) yog ua los ntawm corrosion-cov ntaub ntawv tiv taus-FRP (fiberglass-cov yas siv zog) rau qis- cov tshuab siab, 316L stainless hlau rau nruab nrab- siab siab tshuab- los tiv thaiv H₂S thiab alkaline kua.
Tus nqi khiav haujlwm tsawg
Qhov nqus tau siab siv tau (piv txwv li, 1.2-1.5 kg NaOH ib kg H₂S tshem tawm); rau cov tshuab regenerable (xws li, amine), tus nqi rov qab siv dua li 95%, txo cov tshuaj noj.
Qhov zoo ntawm peb lub tuam txhab cov khoom
Nyob rau hauv cov ntsiab lus ntawm cov kev cai ib puag ncig nruj zuj zus thiab cov kev xav tau kev nyab xeeb ntawm kev lag luam, kev tsim kho kom zoo yog lub hauv paus ntawm kev ua kom muaj kev ua kom huv huv thiab ntev ntev - kev ruaj ntseg.

Peb lub tuam txhab nruj me ntsis ua raws li ISO9001 kev tswj hwm zoo thoob plaws hauv tag nrho cov phiaj xwm kev ua neej, suav nrog kev tsim, kev yuav khoom, kev tsim khoom, thiab commissioning. Thaum lub sijhawm tsim qauv, cov kws ua haujlwm laus ua haujlwm hla -kev tshuaj xyuas ntawm cov duab kos thiab cov txheej txheem tsis raug txhawm rau tshem tawm cov qauv tsim; rau cov khoom tseem ceeb (nqus ntauwd packing, H₂S analyzers, corrosion-cov twj tso kua mis), peb xaiv cov khoom los ntawm cov khoom zoo-paub hom (xws li, Sulzer packing, Emerson analyzers) thiab ua cov khoom soj ntsuam raws li cov kev qhia tshwj xeeb (xws li, cov khoom siv muaj pes tsawg leeg kuaj, ntsuas ntsuas siab). Thaum lub sij hawm tsim khoom, lub tshuab nqus tsev tau dhau los ua qhov tsis zoo{10}} kuaj kev puas tsuaj (UT rau welds, RT rau cov tuab- cov phab ntsa) thiab ntsuas hydrostatic siab (1.25 npaug ntawm cov qauv tsim) kom ntseeg tau tias kev sib khi thiab lub zog muaj zog. Ua ntej xa khoom, lub kaw lus tau dhau 72-teev kev ntsuas kev ua haujlwm tas mus li- txheeb xyuas H₂S kev tshem tawm kev ua haujlwm, kev poob siab, thiab kev daws teeb meem-kom ntseeg tau tias txhua qhov ntsuas tau ua raws li cov qauv tsim.
Peb suav hais tias cov khoom lag luam zoo li lub neej ntawm kev lag luam thiab tau cog lus tias yuav xa cov khoom siv "zero-fault" . Txhua lub kaw lus tau dhau los ua ntau yam - theem kev tswj tau zoo: lub tshuab nqus tsev muaj lub neej tsim muaj ntau dua lossis sib npaug li 20 xyoo, thiab corrosion- cov txheej tiv thaiv (rau FRP yees) muaj cov tshuaj tsw qab ntsev ntau dua lossis sib npaug li 1000 teev; lub kaw lus tswj tsis siv neeg yog nruab nrog dual redundancy (xws li, pH sensor thaub qab) kom tsis txhob raug kaw vim yog ib qho - cov khoom tsis ua haujlwm; lub sijhawm nruab nrab nruab nrab ntawm qhov tsis ua haujlwm (MTBF) tshaj 8000 teev. Peb muab cov ntaub ntawv pov thawj zoo, suav nrog cov ntaub ntawv pov thawj, tsis yog -cov ntaub ntawv soj ntsuam kev puas tsuaj, thiab cov ntawv tshaj tawm kev ua haujlwm, thiab xyuas kom lub Hoobkas tsim nyog ntawm cov khoom yog 100%.
Kev ua tau zoo tom qab- kev muag khoom yog tus yuam sij rau kev ua haujlwm tsis tu ncua ntawm lub kaw lus. Thaum tau txais kev thov kev pabcuam rau cov neeg siv khoom, peb pab pawg kws tshaj lij muab kev tawm tswv yim thawj zaug hauv 12 teev (24/7) hauv xov tooj, email, lossis kev sib tham hauv video- suav nrog kev kuaj mob (xws li kev tshem tawm tsis zoo los ntawm cov alkali concentration tsawg) thiab cov kev daws teeb meem ua ntej. Rau cov teeb meem uas tuaj yeem daws tau nyob deb (piv txwv li, kev hloov pauv parameter, kev tswj hwm qhov system calibration), peb qhia cov neeg siv khoom kom ua tiav kev daws teeb meem hauv 24 teev; rau ntawm - qhov kev xav tau ntawm kev saib xyuas qhov chaw (xws li, hloov ntim, kho lub twj tso kua mis), peb xa cov engineers tsis pub dhau 48 teev (hauv tsev) lossis 72 teev (thoob ntiaj teb) tom qab lees paub qhov kev thov. Peb kuj muab kev pabcuam kev tiv thaiv tsis tu ncua (xws li kev tshuaj xyuas corrosion txhua xyoo, kev taw qhia kev hloov pauv hloov pauv) thiab cov khoom seem muab lav kom txo qis cov khoom siv poob qis.
Peb cov tshuab hluav taws xob hydrogen sulfide tshem tawm tau dav lees paub los ntawm cov tuam txhab ua lag luam hauv lub zog, petrochemical, thiab kev tiv thaiv ib puag ncig kev lag luam vim lawv txoj kev ntseeg siab thiab kev ua haujlwm zoo. Cov neeg siv khoom ib txwm muaj xws li: cov chaw tsim hluav taws xob tsim hluav taws xob, cov chaw tsim hluav taws xob tawm - kev kho roj, kev kho dej khib nyiab tawm - roj thiab biogas purification project.
