China Small ndi Yapakatikati Mpweya Kulekana Unit Industrial Liquid Oxygen Plant Liquid Nayitrojeni Plant

China Small ndi Sizine Air kupatukana Unit Industrial Madzi Oxygen Plant Madzi Nayitrojeni Plant,
China Liquid Air Separation Plant,Zamadzimadzi Oxygen Nayitrojeni Zida,

Malingaliro aukadaulo

1.Main magawo a chipangizo

1.1 Mapangidwe azinthu

Dzina lazinthu: gasi wachilengedwe

Kuthamanga kwazinthu zopangira: 0.02mpag (kuthamanga kwa gauge)

Kutentha kwazinthu zopangira: kutentha kozungulira

Kapangidwe kazinthu zopangira (Zosakhalitsa)

1.2Technical zofunika pa mankhwala haidrojeni

Kupanga mphamvu: 235nm3 / h (500kg / D)

Kuyera kwa haidrojeni: H2 ≥ 99.9%

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

Kuthamanga kwa haidrojeni: ≥ 1.6Mpa

Kutentha kwa kunja: ≤ 40 ℃

1.3 Chitsimikizo cha magwiridwe antchito

l Nthawi yapakati pakati pa kulephera kwa zida zamagetsi 8000 maola

l Kusinthasintha kwa ntchito ya chipangizo: 30 ~ 110%

l Moyo wopanga zida zokhazikika ndi zaka 15

1.4 Kamangidwe kake

Malo opangira zida zakunja ndi 26mx10m = 260m2

2. Chigawo cha ndondomeko

2.1 njira zamakono

Kuponderezedwa kwa gasi wachilengedwe ndi kutembenuka

Gasi wachilengedwe kunja kwa malire a batri amayamba kukakamizidwa mpaka 1.6Mpa ndi kompresa, kenako amatenthedwa mpaka pafupifupi 380 ℃ ndi chotenthetsera mpweya wamafuta mu gawo la convection la wokonzanso nthunzi, ndikulowa mu desulfurizer kuti achotse sulfure mu mpweya wodyetsa pansipa. 0.1ppm. Mpweya wopanda sulfurized ndi nthunzi (3.0mpaa) Sinthani chotenthetsera chosakanikirana cha gasi molingana ndi mtengo wa H2O / ∑ C = 3 ~ 4, onjezerani kutentha kupitilira 510 ℃, ndikulowetsani chitoliro chosinthira kuchokera kugulu la gasi lapamwamba. chitoliro chachikulu ndi chapamwamba pigtail chitoliro. Mu chothandizira, methane imachita ndi nthunzi kuti ipange CO ndi H2. Kutentha kofunikira pakusintha kwa methane kumaperekedwa ndi chisakanizo chamafuta omwe amawotchedwa pachowotcha chapansi. Kutentha kwa mpweya wosinthidwa kuchokera ku reformer ndi 850 ℃, ndipo kutentha kwakukulu kumasinthidwa kukhala kutentha kwakukulu. Mpweya wa mankhwala umalowa mu chubu la chimbudzi cha kutentha kwa zinyalala kuti apange nthunzi yodzaza ndi 3.0mpaa. Kutentha kwa kutembenuka kwa mpweya kuchokera ku zinyalala kutentha kukatentha kumatsikira ku 300 ℃, ndiyeno kutembenuka mpweya amalowa kukatentha chakudya preheater madzi, kutembenuka mpweya madzi ozizira ndi kutembenuka mpweya olekanitsa madzi nayenso kulekanitsa condensate ndondomeko condensate, ndi mafuta opangira mafuta amatumizidwa ku PSA.

Gasi wachilengedwe ngati mafuta amasakanizidwa ndi gasi wothamangitsa adsorption desorption, ndiyeno kuchuluka kwa gasi wamafuta mumafuta otenthetsera mafuta kumasinthidwa malinga ndi kutentha kwa gasi komwe kumatuluka wokonzanso. Pambuyo pa kusintha kwa kayendetsedwe kake, gasi wamafuta amalowa m'chowotcha chapamwamba kuti ayake kuti apereke kutentha kwa wokonzanso.

Madzi osungunuka amatenthedwa ndi chotenthetsera chamadzi chosakanizidwa ndi chotenthetsera chamadzi chotenthetsera ndikulowa mu nthunzi yochokera pamoto wotayira gasi ndikukonzanso boiler ya zinyalala.

Kuti madzi a mu boiler akwaniritse zofunikira, pawonjezedwa kachulukidwe kakang'ono ka phosphate solution ndi deoxidizer kuti makulitsidwe ndi dzimbiri la madzi otenthetsera aziyenda bwino. Ng'omayo imangotulutsa gawo lina la madzi opangira boiler kuti liwongolere zolimba zosungunuka zamadzi otenthetsera mu mgolo.

l Pressure swing adsorption

PSA ili ndi nsanja zisanu zotsatsa. One adsorption Tower ili mu adsorption state nthawi iliyonse. The zigawo zikuluzikulu monga methane, carbon dioxide ndi mpweya monoxide mu kutembenuka mpweya amakhala pamwamba pa adsorbent. Hydrogen imasonkhanitsidwa kuchokera pamwamba pa nsanja ya adsorption ngati zinthu zopanda adsorption ndikutumizidwa kunja kwa malire. The adsorbent zodzaza ndi zonyansa zigawo zikuluzikulu ndi desorbent kuchokera adsorbent kudzera sitepe kusinthika. Akasonkhanitsidwa, amatumizidwa kwa wokonzanso ngati mafuta. Masitepe osinthika a nsanja ya adsorption amapangidwa ndi masitepe 12: dontho loyamba la yunifolomu, kutsika kwa yunifolomu yachiwiri, kutsika kwa yunifolomu yachitatu, kutulutsa kutsogolo, kutulutsa m'mbuyo, kuthamangitsidwa, kuwuka kwa yunifolomu yachitatu, kuwuka kwa yunifolomu yachiwiri, kuwuka kwa yunifolomu yoyamba ndi kuwuka komaliza. Pambuyo pa kubadwanso, nsanja ya adsorption imathanso kuchiza mpweya wosinthidwa ndikupanga haidrojeni. Zinsanja zisanu za adsorption zimasinthana kuchita zomwe zili pamwambapa kuti zitsimikizire chithandizo chopitilira. Cholinga chosinthira gasi ndikutulutsa hydrogen mosalekeza nthawi imodzi.
