Kufotokozera Zamalonda
Makina ochotsa gasi wa hydrogen sulfide (omwe amadziwikanso kuti H₂S purification unit) ndi zida zonse zomwe zimaphatikiza kuchiritsa, kuyeretsa, ndi -kuchiritsa pambuyo.
Mfundo yake yaikulu imasiyana ndi njira zamakono: kuyamwa kwa mankhwala kumagwiritsa ntchito njira za alkaline (mwachitsanzo, sodium hydroxide, amine) kuti igwirizane ndi H₂S; kutengera thupi kumadalira zotsatsa (mwachitsanzo, activated carbon, molecular sieves) kuti agwire H₂S; Kuchotsa kwachilengedwe kumagwiritsa ntchito tizilombo toyambitsa matenda kuti tiyike H₂S kukhala zinthu zopanda vuto.
Ikhoza kuwongolera mokhazikika zinthu za H₂S zomwe zili mugasi wothira kuti zigwirizane ndi miyezo ya dziko (monga, GB 18918 ya madzi otayira opanda{3}}gasi, GB 17820 ya gasi wachilengedwe) ndipo ndi chitsimikizo chofunikira kwambiri pakupanga mafakitale otetezeka komanso kuteteza chilengedwe.
Mfundo yogwira ntchito
Njira yogwirira ntchito ya Hydrogen Sulfide Removal (kutenga njira yodziwika bwino ya "pretreatment + chemical absorption + post-mankhwala" monga chitsanzo) ikhoza kufotokozedwa mwachidule monga masitepe asanu ofunikira: pretreatment gas → chemical mayamwidwe → njira yothetsera vutoli → mankhwala oyeretsedwa
Kukonzekera kwa Gasi:H₂S-yokhala ndi gasi choyamba imalowa mu ng'oma yogogoda ndi kusefa kuti ichotse madontho amadzimadzi (madzi, mafuta) ndi tinthu tolimba (fumbi, zonyansa) zokhala ndi tinthu tating'ono Kuposa kapena kofanana ndi 5 μm. Izi zimalepheretsa kutsekeka kwa nsanja zoyamwitsa/mapaipi ndipo zimapewa kuchepetsa ntchito ya ma absorbents/mayankho.
Mayamwidwe a Chemical:Gasi wotenthedwa kale amayenderera mmwamba kuchokera pansi pa nsanjayo, pomwe 5-15% ya alkaline absorbent (monga sodium hydroxide solution ya low-CO₂ gas, MDEA amine solution for high-CO₂ gas) amapopera kuchokera pamwamba. Pabedi lodzaza (lodzadza ndi kulongedza kokhala ngati mphete), mpweya ndi madzi zimalumikizana kwathunthu: H₂S imakumana ndi choyamwitsa (mwachitsanzo, H₂S + 2NaOH → Na₂S + 2H₂O) kupanga mchere wosungunuka, womwe umalowetsedwa pansi pa nsanja ndi yankho.
Kuzungulira kwa mayankho:Njira yothetsera vutoli ikatha kuyamwa H₂S imasonkhanitsidwa munsanja pansi pa nsanja, kenako imapoperedwa ku chotenthetsera kutentha kuti izizirike (kuwongolera kutentha kwa 30-40 digiri kuti isunge kuyamwa bwino), ndipo pomaliza imabwezeretsanso pamwamba pa nsanjayo. Kagawo kakang'ono ka "mankhwala ogwiritsidwa ntchito" (wokhala ndi mchere wochepa wa alkali) amatulutsidwa mosalekeza kuti apewe kuchuluka kwa mchere.
Chithandizo chamankhwala chogwiritsidwa ntchito:Njira yothetsera yomwe yatulutsidwa (yokhala ndi sodium sulfide/ammonium sulfide) imatumizidwa ku thanki ya neutralization, komwe imathandizidwa ndi okosijeni (mwachitsanzo, hydrogen peroxide) kutembenuza sulfide kukhala sulfure kapena sulfate yopanda vuto, kenako imatulutsidwa pambuyo pokwaniritsa miyezo yamadzi onyansa. Pamakina akulu-akuluakulu, yankho litha kupangidwanso (monga, kuchotsa amine solution) kuti mugwiritsenso ntchito choyamwitsa.
Kutuluka kwa gasi woyeretsedwa:H₂S-yotuluka gasi yotuluka pamwamba pa nsanja yoyamwitsa, imadutsa pochotsa nkhungu kuchotsa madontho amadzimadzi otsalira (zotsalira zotsalira), kenako amatumizidwa kumayendedwe akumunsi (monga mapaipi a gasi, poyatsira moto) kapena kutulutsidwa pambuyo pokwaniritsa miyezo ya chilengedwe.
Hydrogen Sulfide Gas Removal System Core Features
Mkulu kuchotsa dzuwa
Pansi pa kasinthidwe wamba, H₂S kuchotsa bwino ndi Kuposa kapena kofanana ndi 98%; yokhala ndi makonda (monga,-mayamwidwe ambiri,{4}}zokometsera bwino kwambiri), imatha kufika 99.9%, kuchepetsa kuchulukira kwa H₂S kuchoka pa 10,000 ppm kufika pansi pa 1 ppm.
Lonse kugwiritsa ntchito
Imatha kuthana ndi mitsinje ya gasi yokhala ndi ndende ya H₂S kuyambira 50 ppm mpaka 50,000 ppm, ndikusintha magawo osiyanasiyana agasi (mwachitsanzo, okhala ndi/popanda CO₂, ma hydrocarbon) posintha ma absorbents/adsorbents.
Ntchito yokhazikika
Zokhala ndi makina owongolera okha (pH metres, H₂S analyzers pa intaneti, owongolera ma flow) kuti aziwunika magawo ofunikira munthawi yeniyeni; pamene kulowetsedwa kwa H₂S kusinthasintha, dongosololi limasintha mlingo woyamwa / kuthamanga kwa mphindi 15-30 kuti ukhalebe wokhazikika.
Kukana dzimbiri
Zigawo zazikuluzikulu (mayamwidwe nsanja, mapaipi, mapampu) amapangidwa ndi dzimbiri-zosagwira ntchito{1}}FRP (fiberglass-pulasitiki yolimba) ya makina otsika{3}}otsika, 316L zitsulo zosapanga dzimbiri{5}}zokhala ndi mphamvu zambiri{{6}zolimbana ndi alrokalision solution.
Mtengo wotsika mtengo
The absorbent imakhala ndi mlingo wogwiritsa ntchito kwambiri (mwachitsanzo, 1.2-1.5 kg NaOH pa kg H₂S yochotsedwa); kwa machitidwe osinthika (mwachitsanzo, amine), kuchuluka kwa kuyamwanso kumaposa 95%, kuchepetsa kumwa mankhwala.
Ubwino wazinthu zamakampani athu
Pankhani ya malamulo okhwima a chilengedwe ndi zofunika za chitetezo cha mafakitale, kamangidwe kake ndi maziko owonetsetsa kuti kuyeretsedwa bwino ndi kukhazikika-kwanthawi yayitali. Kampani yathu ili ndi gulu la akatswiri odziwa zaukadaulo omwe ali ndi zaka zopitilira 25 zakuyeretsa gasi, odziwa bwino miyezo yapakhomo ndi yakunja monga GB 150 (zotengera zokakamiza), API 581 (H₂S control corrosion), ISO 13130 (kuyeretsa gasi), ndi EPA Njira 8 (H₂S kuzindikira). Timapereka mapangidwe makonda malinga ndi katundu wa gasi wamakasitomala (kukhazikika kwa H₂S, zomwe zili mu CO₂, kapangidwe ka hydrocarbon), kuthamanga kwa magwiridwe antchito, ndi zofunikira zotulutsa mpweya: pamakina agasi achilengedwe, timakulitsa malingaliro oyendetsa njira ya amine kuti tipewe kusokoneza kwa CO₂; pamakina a biogas, timagwiritsa ntchito -zopaka zonyansa kuti tipewe kutsekeka kwa zinthu. Timasiya ma tempuleti a ".chimodzi-zokwanira{12}}zonse" ndikuchita zoyeserera zatsatanetsatane za misala/hydraulic pa projekiti iliyonse kuti tiwonetsetse kuti zikuyenda bwino.
Kampani yathu imagwiritsa ntchito mosamalitsa kasamalidwe kabwino ka ISO9001 munthawi yonse ya moyo wa polojekiti, kupanga mapangidwe, kugula, kupanga, ndi kutumiza. Panthawi yokonza mapulani, mainjiniya akuluakulu amatsimikizira{2}}zonse zojambulira ndi kukonza zinthu kuti athetse zolakwika; pazigawo zofunika kwambiri (mayamwidwe tower packing, H₂S analyzers, corrosion-pampu zosagwira), timasankha zinthu zochokera{4}}zodziwika bwino (monga, Sulzer packing, Emerson analyzers) ndikuchita kuyendera molingana ndi ukadaulo (monga kuyesa zinthu, kuyezetsa kukana kukanika). Popanga, ma absorption tower amayezetsa{10}osawononga (UT for welds, RT for thick{{11}walled parts) ndi hydrostatic pressure test (1.25 times the design pressure) kuti zitsindike ndi kulimba kwa kapangidwe kake. Isanatumizidwe, makinawa amayesa maola 72-osalekeza{16}}kutsimikizira kuti H₂S ikugwira bwino ntchito, kuchepetsa kuthamanga kwa magazi, komanso kugwiritsa ntchito njira yothetsera vutoli-kuonetsetsa kuti zizindikiro zonse zikukwaniritsa zofunikira za kapangidwe kake.
Timawona kuti zinthu zili bwino ngati gwero lalikulu la bizinesi ndipo tadzipereka kupereka "ziro-zolakwika" zida. Dongosolo lililonse limakhala ndi mphamvu zambiri-zowongolera zinthu: nsanjayo imakhala ndi moyo wopangidwa Woposa kapena wofanana ndi zaka 20, ndipo dzimbiri{4}}zotchingira zosagwira ntchito (za FRP towers) zimakhala ndi mphamvu yotha kupopera mchere wamchere Woposa kapena wofanana ndi maola 1000; makina odziwongola okha ali ndi zida ziwiri (monga, pH sensor yosunga zobwezeretsera) kupeŵa kuzimitsa chifukwa cha kulephera-chinthu chimodzi; nthawi ya dongosolo pakati pa zolephera (MTBF) imaposa maola 8000. Timapereka ma certification amtundu uliwonse, kuphatikiza masatifiketi azinthu,{11}malipoti osawononga, ndi malipoti oyesa momwe zinthu zimagwirira ntchito, ndikuwonetsetsa kuti zinthu zoyenerera kufakitale ndi 100%.
Kuchita bwino pambuyo pa-ntchito zogulitsa ndiye mfungulo yowonetsetsa kuti makinawa akugwira ntchito mosalekeza. Tikalandira pempho la chithandizo cha kasitomala, gulu lathu laukadaulo limapereka malingaliro oyambira pasanathe maola 12 (24/7) kudzera pa foni, imelo, kapena msonkhano wapavidiyo-kuphatikiza kuzindikira kuti pali vuto (monga, kuchepa kwa kuchotsa chifukwa cha kuchuluka kwa alkali) ndi mayankho oyambira. Pazinthu zomwe zitha kuthetsedwa patali (mwachitsanzo, kusintha magawo, kuwongolera dongosolo), timawongolera makasitomala kuti amalize kuthetsa mavuto mkati mwa maola 24; pa-zofunika kukonza malo (monga zolongera m'malo, kukonza mapampu), timatumiza mainjiniya mkati mwa maola 48 (zanyumba) kapena maola 72 (zapadziko lonse) titatsimikizira zomwe akufuna. Timaperekanso ntchito zodzitetezera nthawi zonse (mwachitsanzo, kuyang'anira dzimbiri pachaka, chitsogozo cholowera m'malo) komanso zitsimikizo zoperekera zida zosinthira kuti zichepetse kutha kwa zida.
Makina athu ochotsera mpweya wa hydrogen sulfide amadziwika kwambiri ndi mabizinesi otsogola m'mafakitale amagetsi, petrochemical, ndi chitetezo cha chilengedwe chifukwa chodalirika komanso kuchita bwino. Makasitomala odziwika bwino ndi awa: malo opangira gasi, makina oyeretsera mafuta a gasi, -oyeretsa gasi, kuthira madzi oipa-ntchito yoyeretsa gasi ndi biogas.
Kampani yathu imapereka njira zosinthika zothandizirana kuti zikwaniritse zosowa zosiyanasiyana zamakasitomala:
