Yopangidwa ndi 500KG Hydrogen generation unit kuchokera ku gasi wachilengedwe

Makhalidwe onse

Mapangidwe onse a skid amasintha momwe amakhazikitsira patsamba. Kudzera processing, kupanga, mipope ndi skid kupanga mu kampani, lonse ndondomeko kupanga kulamulira zipangizo, kudziwika cholakwa ndi mayeso kuthamanga mu kampani anazindikira mokwanira, amene amathetsa vuto kulamulira khalidwe chiopsezo chifukwa wosuta pa malo yomanga, ndipo moona. chimakwaniritsa dongosolo lonse kulamulira khalidwe.

Zogulitsa zonse zimayikidwa mu kampani. Lingaliro la kupanga mu fakitale limatengedwa. Pambuyo podutsa chitsimikiziro cha fakitale, amasonkhanitsidwa molingana ndi dongosolo la disassembly lomwe linakhazikitsidwa ndikutumizidwa ku malo ogwiritsira ntchito kuti agwirizanenso. Voliyumu yomanga pamalopo ndi yaying'ono ndipo nthawi yomanga ndi yochepa.

Mlingo wa automation ndi wapamwamba kwambiri. Kugwiritsiridwa ntchito kwa chipangizochi kungathe kuyang'aniridwa ndi kuyang'aniridwa bwino kudzera mu dongosolo lapamwamba, ndipo deta yofunikira ikhoza kutumizidwa ku seva yamtambo mu nthawi yeniyeni kuti iwonetsedwe kutali, kuti muzindikire kusamalidwa kosagwiritsidwa ntchito pa malo.

Kuyenda kwa chipangizocho kumakhala kolimba kwambiri. Malingana ndi momwe polojekitiyi ikuyendera, chipangizochi chikhoza kusamutsidwa kupita kumalo ena ndikugwiritsidwa ntchito pambuyo poti skid kukwera kachiwiri, kuti azindikire kugwiritsidwanso ntchito kwa zipangizo ndikuwonetsetsa phindu lalikulu la mtengo wa zipangizo.

Malinga ndi kufunikira kwa haidrojeni pa siteshoni ya hydrogenation, tsatirani dongosolo lokhazikika komanso kapangidwe kake kaphatikizidwe molingana ndi gawo lanjira kuti muzindikire kupanga kokhazikika kwazinthu ndikupanga zinthu zofananira, zomwe ndizosavuta kuwongolera zida za ogwiritsa ntchito, zotsalira wamba. magawo ndi kuchepetsa mtengo wa ntchito ya unit.
Mwachidule, gawo lopangira gasi lachilengedwe la skid lomwe limapangidwa ndi haidrojeni ndiloyenera kwambiri gwero la haidrojeni kuti ligwiritse ntchito mtsogolo mwa hydrogenation station.

Malingaliro aukadaulo

Kuponderezedwa kwa gasi wachilengedwe ndi kutembenuka

Gasi wachilengedwe kunja kwa malire a batri amayamba kukakamizidwa mpaka 1.6Mpa ndi kompresa, kenako kutenthedwa mpaka pafupifupi 380 ℃ ndi chotenthetsera mpweya wamafuta mugawo la ng'anjo yosinthira nthunzi, ndikulowa mu desulfurizer kuchotsa sulfure mu gasi wodyetsa. pansi pa 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. M'malo othandizira, methane imachita ndi nthunzi kuti ipange CO ndi H2. Kutentha kofunikira pakusintha kwa methane kumaperekedwa ndi kusakaniza kwamafuta komwe kumatenthedwa pansi. Kutentha kwa gasi wosinthidwa kuchokera ku ng'anjo yokonzanso ndi 850 ℃, ndipo kutentha kwakukulu kumasinthidwa kukhala kutentha kwakukulu. Mpweya wa mankhwala umalowa mu chubu cha 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 mpweya wothamanga wa adsorption desorption, ndiyeno kuchuluka kwa gasi wamafuta muchotenthetsera chamafuta kumasinthidwa molingana ndi kutentha kwa mpweya komwe kumatuluka ng'anjo yokonzanso. Pambuyo pa kusintha koyenda, gasi wamafuta amalowa m'chowotcha chapamwamba kuti ayake kuti apereke kutentha kwa ng'anjo yokonzanso.

Madzi okhathamira amatenthedwa ndi chotenthetsera chamadzi chosakanizidwa ndi chotenthetsera chamadzi chotenthetsera madzi ndikulowa mu nthunzi yochokera ku boiler ya zinyalala za 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.

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 zida zopanda adsorption ndikutumizidwa kunja kwa malire. The adsorbent zodzaza ndi zonyansa zigawo zikuluzikulu ndi desorbent kuchokera adsorbent kudzera sitepe kusinthika. Akasonkhanitsidwa, amatumizidwa ku ng'anjo yokonzanso 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, kupukuta, kukwera kwa yunifolomu yachitatu, kukwera 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.
