China Small and Medium Size Air Separation Unit Industrial Liquid Oxygen Plant Liquid Nitrogen Plant, Chomera cha China,
Chomera Chopatulira Mpweya Wamadzimadzi ku China, Zida za Nayitrogeni ya Oxygen ya Madzi,

Malingaliro aukadaulo

1Magawo akuluakulu a chipangizocho

1.1 Mikhalidwe ya kapangidwe

Dzina la zinthu zopangira: gasi wachilengedwe

Kupanikizika kwa zinthu zopangira: 0.02mpag (kupanikizika koyezera)

Kutentha kwa zinthu zopangira: kutentha kozungulira

Kapangidwe ka zinthu zopangira (Zosakhalitsa)

1.2 Zofunikira paukadaulo wa haidrojeni ya chinthu

Mphamvu yopanga: 235nm3 / h (500kg / D)

Kuyera kwa haidrojeni: H2 ≥ 99.9%

Kugwiritsa ntchito gasi wachilengedwe: 110m3 / h (LHV yoposa 8500Kcal / m3)

Kuthamanga kwa haidrojeni: ≥ 1.6Mpa

Kutentha kwa malo otulutsira: ≤ 40 ℃

1.3 Chitsimikizo cha magwiridwe antchito

l Avereji ya nthawi pakati pa kulephera kwa zida zamagetsi ndi maola 8000

l Chipangizo ntchito kusinthasintha: 30 ~ 110%

l Moyo wa kapangidwe ka zida zokhazikika ndi zaka 15

1.4 Kapangidwe kake konse

Malo okonzera chipangizo chakunja ndi 26mx10m = 260m2

2. Gawo la ndondomeko

2.1 njira zaukadaulo

Kupsinjika ndi kusintha kwa mpweya wachilengedwe

Mpweya wachilengedwe womwe uli kunja kwa malire a batri umayikidwa kaye pa 1.6Mpa ndi compressor, kenako umatenthedwa kufika pa 380 ℃ ndi preheater ya gasi yodyetsa mu gawo la convection la nthunzi yosinthira, ndikulowa mu desulfurizer kuti muchotse sulfure mu mpweya wodyetsa pansi pa 0.1ppm. Mpweya wodyetsa wosasungunuka ndi nthunzi yopangira (3.0mpaa) Sinthani preheater ya gasi yosakaniza malinga ndi mtengo wodziyimira wa H2O / ∑ C = 3 ~ 4, onjezerani kutentha mpaka kupitirira 510 ℃, ndikulowa mofanana mu chitoliro chosinthira kuchokera ku chitoliro chachikulu chosonkhanitsa gasi chapamwamba ndi chitoliro chapamwamba cha pigtail. Mu gawo la catalyst, methane imachita ndi nthunzi kuti ipange CO ndi H2. Kutentha kofunikira kuti methane isinthe kumaperekedwa ndi mafuta osakaniza omwe amawotchedwa pa burner yapansi. Kutentha kwa mpweya wosinthidwa kuchokera ku reformer ndi 850 ℃, ndipo kutentha kwakukulu kumasinthidwa kukhala kutentha kwakukulu. Mpweya wa mankhwala umalowa m'mbali mwa chubu cha chitoliro chotenthetsera zinyalala kuti upange nthunzi yodzaza ya 3.0mpaa. Kutentha kwa mpweya wosinthira kuchokera ku boiler yotenthetsera zinyalala kumatsika kufika pa 300 ℃, kenako mpweya wosinthira umalowa mu chotenthetsera madzi chotenthetsera boiler, chotenthetsera madzi chosinthira ndi cholekanitsa madzi chosinthira kuti chilekanitse condensate ndi process condensate, ndipo mpweya wosinthira umatumizidwa ku PSA.

Mpweya wachilengedwe monga mafuta umasakanizidwa ndi mpweya wothira madzi wothira madzi wothira madzi, kenako kuchuluka kwa mpweya wothira mafuta mu preheater ya gasi yamafuta kumasinthidwa malinga ndi kutentha kwa mpweya pamalo otulukira mpweya wothira madzi. Pambuyo posintha kayendedwe ka madzi, mpweya wothira mafuta umalowa mu choyatsira chapamwamba kuti uyake kuti upereke kutentha kwa wothira madzi.

Madzi osungunuka mchere amatenthedwa ndi chotenthetsera madzi chosungunuka ndi chotenthetsera madzi chotenthetsera boiler ndipo amalowa mu nthunzi yochokera ku chotenthetsera cha zinyalala za gasi ndi chotenthetsera cha zinyalala za gasi chokonzanso.

Kuti madzi ophikira boiler akwaniritse zofunikira, phosphate solution ndi deoxidizer ziyenera kuwonjezeredwa kuti ziwongolere kukula ndi dzimbiri la madzi ophikira boiler. Boiler iyenera kutulutsa madzi ena ophikira boiler nthawi zonse kuti ilamulire kuchuluka kwa madzi ophikira boiler omwe ali mu boiler.

l Kuthamanga kwa kugwedezeka kwa kuthamanga

PSA imakhala ndi nsanja zisanu zokoka madzi. Nsanja imodzi yokoka madzi imakhala mu mkhalidwe wokoka madzi nthawi iliyonse. Zigawo monga methane, carbon dioxide ndi carbon monoxide mu mpweya wosinthika zimakhala pamwamba pa mpweya wokoka madzi. Hydrogen imasonkhanitsidwa kuchokera pamwamba pa nsanja yokoka madzi ngati zigawo zosakoka madzi ndipo imatumizidwa kunja kwa malire. Chokoka madzi chodzazidwa ndi zigawo zodetsedwa chimachotsedwa mu adsorbent kudzera mu sitepe yokonzanso. Pambuyo posonkhanitsa, chimatumizidwa kwa wokonzanso ngati mafuta. Masitepe okonzanso a nsanja yokoka madzi amapangidwa ndi masitepe 12: choyamba kutsika kofanana, chachiwiri kutsika kofanana, chachitatu kutsika kofanana, kutsogolo kutulutsa madzi, kutulutsira madzi m'mbuyo, kutsuka, chachitatu kukwera kofanana, chachiwiri kukwera kofanana, choyamba kukwera kofanana ndi kukwera komaliza. Pambuyo pokonzanso, nsanja yokoka madzi imathanso kuchiza mpweya wosinthidwa ndikupanga haidrojeni. Nsanja zisanu zokoka madzi zimasinthana kuti zichite masitepe omwe ali pamwambapa kuti zitsimikizire kuti mpweya ukupitira patsogolo. Cholinga chosinthira mpweya ndikupanga haidrojeni nthawi zonse nthawi imodzi.

2.2 Zipangizo zazikulu zogwirira ntchito

2.3 Tebulo lalikulu la kugwiritsa ntchito
