Kufotokozera Zamalonda
The caustic scrubber for H₂S kuchotsa (yomwe imadziwikanso kuti alkaline H₂S scrubber) ndi chipangizo choyeretsera mpweya chotengera mfundo zamayamwidwe amankhwala.
Mfundo yake yaikulu ndikubweretsa mpweya wa H₂S-wokhala ndi mpweya wokhudzana ndi caustic solution (sodium hydroxide kapena potaziyamu hydroxide) munsanja yodzaza kapena tray, pomwe H₂S imachita ndi alkali kupanga soluble sodium sulfide (Na₂S) kapena sodium hydrosulfide kuchokera ku H₂S.
Itha kuchepetsa kukhazikika kwa H₂S kukhala pansi pa 10 ppm, kuwonetsetsa chitetezo cha zida zotsika komanso kutsata chilengedwe.
Mfundo yogwira ntchito
Njira yogwirira ntchito ya Kuchotsa kwa Scavenger H2s ikhoza kufotokozedwa mwachidule ngati njira zisanu zazikulu: kuperekera mpweya → kuyamwa mayamwidwe → kufalikira kwa yankho → kugwiritsira ntchito njira yothetsera → kutulutsa mpweya woyeretsedwa
Kukonzekera kwa Gasi:H₂S-yokhala ndi gasi (monga gasi waiwisi wachilengedwe kapena malo oyeretsera{1}}gasi) imalowa kaye mu ng'oma kuti ichotse madontho amadzimadzi ndi tinthu tolimba (kupewa kutsekereza kulongedza ndi kusokoneza kuyamwa bwino).
Mayamwidwe:Mpweya wokhazikika umalowa m'munsi mwa nsanjayo ndikuyenderera m'mwamba, pamene yankho la caustic (2-10% NaOH) limapopera kuchokera pamwamba. Pabedi lodzaza (lodzadza ndi kulongedza mwachisawawa), mpweya ndi madzi zimalumikizana kwambiri, ndipo H₂S imakumana ndi NaOH: H₂S + 2NaOH → Na₂S + 2H₂O (kapena H₂S + NaOH → NaHS + H₂O, kutengera al).
Kuzungulira kwa mayankho:Njira yothetsera vutoli, itatha kuyamwa H₂S, imasonkhanitsa pansi pa nsanjayo ndikuponyedwa pamwamba kuti ibwererenso. Gawo lina la yankho lomwe limagwiritsidwa ntchito limatulutsidwa mosalekeza kuti ndende ya alkali ikhale mumadzi ozungulira (omwe amawunikidwa pamwamba pa 2%).
Chithandizo chamankhwala chogwiritsidwa ntchito:Njira yothetsera vutoli (yomwe ili ndi Na₂S / NaHS) imatumizidwa ku neutralization kapena kukonzanso dongosolo. Ikhoza kuthandizidwa ndi okosijeni (monga hydrogen peroxide) kuti ipange mankhwala a sulfure osavulaza, kapena kupangidwanso pogwiritsa ntchito laimu kuti abwezeretsenso alkali kuti agwiritsidwenso ntchito.
Kutuluka kwa gasi woyeretsedwa:H₂S-yotuluka gasi yotuluka pamwamba pa nsanjayo, imadutsa pochotsa nkhungu kuti ichotse madontho amadzimadzi olowa mkati, kenako imasamutsidwa kupita kunsi kwa mitsinje kapena kutulutsidwa pambuyo pokwaniritsa miyezo.
Caustic Scrubber ya H₂S Removal Core Features
Mkulu kuchotsa dzuwa
Itha kuchepetsa kuchulukira kwa H₂S kuchokera pa masauzande a ppm kufika pansi pa 10 ppm, ndikuchotsa bwino Kuposa kapena kofanana ndi 99%, kukwaniritsa miyezo yokhwima yotulutsa mpweya wachilengedwe (monga Wochepera kapena wofanana ndi 20 ppm wotulutsa mpweya m'mafakitale).
01
Wide mphamvu osiyanasiyana
Kuchuluka-pang'onopang'ono kumayambira pa 100 Nm³/h kufika pa 50,000 Nm³/h, yoyenera-zomera zazing'ono (zomera zamagasi) mpaka zazikulu-zikuluzikulu (zopangira gasi) zoyendera mpweya.
02
Kuyankha mwachangu
Zomwe mayamwidwe zimachitika nthawi yomweyo, zomwe zimapangitsa kuti makinawo azitha kusintha mwachangu kusinthasintha kwa ndende ya H₂S (mkati mwa mphindi 10-30 kuti akhazikike).
03
Ntchito yosavuta
Njirayi ndiyosavuta kuwongolera, ndi magawo ofunika kwambiri (machulukidwe a alkali, kuchuluka kwamadzi-gasi) omwe amatha kusinthidwa pogwiritsa ntchito makina azida kuti agwire bwino ntchito.
04
Kukana dzimbiri
Thupi la nsanjayo ndi zina zamkati mwake zimapangidwa ndi zinthu zosachita dzimbiri ({0}}monga FRP, 316L zitsulo zosapanga dzimbiri) kuti zipirire chilengedwe cha alkaline komanso dzimbiri la sulfide.
05
Ubwino wazinthu zamakampani athu
Pankhani ya malamulo okhwima a chilengedwe, mapangidwe oyengedwa ndi ofunikira kuti atsimikizire kuti kuyamwa bwino ndi kukhazikika kwa ntchito. Kampani yathu ili ndi gulu la akatswiri amisiri omwe ali ndi zaka zopitilira 20 zakuyeretsa gasi, odziwa bwino miyezo yapakhomo ndi yakunja monga GB, API, ASME, ndi EPA. Timapereka kamangidwe kake potengera kapangidwe ka gasi (kuchuluka kwa H₂S, CO₂), mphamvu ya kagwiritsidwe ntchito, ndi zofunika pamankhwala, kuwongolera mtundu wa zolongedwa, madzi-chiyerekezo cha gasi, ndi m'mimba mwake ya nsanja kuti achulukitse kuchotsedwa kwa H₂S kwinaku akuchepetsa kumwa kwa alkali (kawirikawiri 0.5-1.2 kg NaOH pa kg H₂S yochotsedwa). Timapewa ma tempulo okhazikika ndikuwerengera mwatsatanetsatane ma hydraulic ndi kusamutsa misa pa projekiti iliyonse kuti igwirizane ndi momwe ntchito ikugwirira ntchito.
Kampani yathu imagwiritsa ntchito mosamalitsa kasamalidwe kabwino ka ISO9001 pa nthawi yonse ya polojekitiyi, kupanga mapangidwe, kugula, kupanga, ndi kutumiza. Panthawi ya mapangidwe, kayesedwe kachitidwe (pogwiritsa ntchito Aspen Plus) amatsimikizira kuyamwa bwino ndi kutsika kwamphamvu; zigawo zikuluzikulu (kulongedza, mapampu, mavavu) amawunika mosamalitsa zomwe zikubwera kuti zitsimikizire kuti zikutsatira mfundo zakuthupi ndi magwiridwe antchito; kupanga tower body motsatira milingo ya zotengera zokakamiza (GB 150 kapena ASME BPVC), popanda -kuyesa kowononga (UT, RT) kwa ma welds; Kutumiza kumaphatikizapo kuyezetsa ntchito mosalekeza kwa maola 72-kutsimikizira kuti H₂S ikugwira ntchito moyenera, kutsika kwamphamvu, ndi zizindikiro zogwiritsa ntchito alkali. Kasamalidwe mwadongosolo kameneka kamapangitsa kuti zinthu zikhale bwino komanso kuti ziperekedwe pa nthawi yake.
Timaona kuti zinthu zili bwino ngati gwero lamphamvu labizinesi, odzipereka kuti apereke-zotsuka zodalirika kwambiri. Chida chilichonse chimayang'aniridwa bwino kwambiri: nsanjayo imagwiritsa ntchito dzimbiri-zosasunthika zomwe zimakhala ndi moyo wazaka zopitilira 15; kulongedza kumasankhidwa pamalo okwera kwambiri komanso kutsika kwapang'onopang'ono (monga kulongedza kwa PP ndi moyo wautumiki Kuposa kapena kofanana ndi zaka 5); makina owongolera okha (kuphatikiza ma pH metres, ma flow meters, ndi mapampu a dosing alkali) amaonetsetsa kuti ntchito ikuyenda bwino. Timatsimikizira kuti gasi woyeretsedwa amakwaniritsa miyezo yotulutsa mpweya, ndi kuyenerera kwa fakitale ya 100%.
Kuchita bwino pakatha-ntchito zogulitsa ndikofunikira kuti muwonetsetse kuti zikugwira ntchito mosalekeza. Tikalandira pempho la ntchito, gulu lathu laukadaulo limapereka mayankho oyambira mkati mwa maola 8 (24/7) kudzera pa foni, imelo, kapena kanema. Pazifukwa zakutali-zomwe zingathetsedwe (monga kusintha magawo, kuwongolera zovuta pamakina), timawongolera mawola 24; pa-zofunika kukonza malo (monga zolongera, kukonza mapampu), mainjiniya amatumizidwa mkati mwa maola 48 (zanyumba) kapena maola 72 (zapadziko lonse). Timaperekanso ntchito zokonza nthawi zonse (mwachitsanzo, kuyang'anira dzimbiri, kuyesa kwachangu) kuti tiwonjezere moyo wa zida.
Caustic Scrubber yathu ya H₂S Removal imadziwika kwambiri ndi mabizinesi otsogola m'magulu amphamvu ndi zachilengedwe, monga Shell, ExxonMobil, Sinopec, ndi Veolia, chifukwa chakuchita bwino kwawo komanso kudalirika kwamakampani.
Kampani yathu imatha kupereka makina opangira makonda monga ma projekiti a turnkey (kuphatikiza mapangidwe, kupanga, kukhazikitsa, ndi kutumiza), komanso kupereka ntchito zaukadaulo monga kukhathamiritsa kwa njira ndi maphunziro oyendetsa. Kwa makasitomala omwe ali ndi zosowa zosakhalitsa, timaperekanso ntchito zobwereketsa za skid-zokolopa zokwera, kupangitsa kuti zisankho zotha kusintha malinga ndi zomwe polojekiti ikufuna.
