Kugwiritsa ntchito
Kubwezeretsanso H2kuchokera ku H2-kusakaniza kwa gasi wochuluka monga gasi wosinthira, gasi woyengedwa, gasi wamadzi, gasi wamzinda, mpweya wa coke-ovuni, mpweya woyaka, mpweya wa methanol, gasi wa mchira wa methanol, gasi la formaldehyde, mpweya wouma wa FCC wamafuta oyeretsera mafuta, gasi wosinthira mchira ndi magwero ena amafuta. ndi H2.
Mawonekedwe
1. TCWY imadzipereka kupanga ndi kupanga Pressure Swing Adsorption Plant yotsika mtengo yokhala ndi ntchito zapamwamba.Malinga ndi zomwe makasitomala amafuna komanso mawonekedwe opangira, njira yoyenera kwambiri yaukadaulo, njira yopangira njira, mitundu ya adsorbents ndi gawo zimaperekedwa kuti zitsimikizire zokolola za gasi wogwira ntchito komanso kudalirika kwa index.
2. Mu dongosolo la ntchito, phukusi la mapulogalamu okhwima komanso otsogola amatengedwa kuti apititse patsogolo nthawi ya adsorption, yomwe imapangitsa kuti chomeracho chizigwira ntchito mopanda ndalama zambiri kwa nthawi yaitali ndikukhala opanda mphamvu ya luso lamakono ndi ntchito yosasamala ya ogwira ntchito. .
3. Tekinoloje yodzaza kwambiri ya adsorbents imatengedwa kuti ipitirire kuchepetsa mipata yakufa pakati pa zigawo za bedi ndikuwonjezera kuchira kwa zigawo zothandiza.
4. Kutalika kwa moyo wa ma valve athu opangidwa ndi PSA okhala ndi matekinoloje apadera ndi oposa 1 miliyoni nthawi.
(1) Njira ya Adsorption
Mafuta a Feed amalowa munsanja ya adsorption kuchokera pansi pa nsanja (Mmodzi kapena angapo amakhala nthawi zonse adsorbing).Kupyolera mu kusankha adsorbents zosiyanasiyana adsorbents mmodzi pambuyo mmodzi, zonyansa ndi adsorbed ndi un-adsorbed H2 kutuluka kuchokera pamwamba pa nsanja.
Pamene malo akutsogolo a zone kutengerapo misa (adsorption patsogolo malo) wa adsorption chidetso afika potuluka reserved gawo la bedi wosanjikiza, zimitsani valavu chakudya mpweya chakudya ndi valavu potulutsira wa mankhwala mpweya, kusiya kutsatsa.Kenako bedi la adsorbent limasinthidwa kukhala njira yosinthika.
(2) Kukhumudwa Kofanana
Pambuyo pa njira ya adsorption, motsatira njira ya adsorption ikani kuthamanga kwambiri kwa H2 pa nsanja ya adsorption mu nsanja ina yotsika yotsika yomwe yatha kusinthika.Njira yonseyi sikuti ndi njira yokhayo yochepetsera nkhawa, komanso njira yobwezeretsanso H2 ya malo ogona.Njirayi imaphatikizapo kangapo pa-mtsinje wodetsa nkhawa, kotero kuti kuchira kwa H2 kungathe kutsimikiziridwa mokwanira.
(3)Pathwise Pressure Release
Pambuyo ofanana depressurization ndondomeko, m'mbali malangizo adsorption mankhwala H2 pamwamba pa nsanja adsorption mwamsanga anachira mu pathwise kuthamanga kumasulidwa mpweya bafa thanki (PP Gasi Buffer Tank), gawo ili la H2 adzakhala ntchito ngati kubadwanso gasi gwero la adsorbent. depressurization.
(4) Reverse Depressurization
Pambuyo pa njira yotulutsa mphamvu ya pathwise, malo otsogolera adsorption afika potuluka pabedi.Panthawiyi, kupanikizika kwa nsanja ya adsorption kumachepetsedwa kufika pa 0,03 barg kapena kupitirira pa njira yolakwika ya adsorption, zonyansa zambiri za adsorbed zimayamba kuchotsedwa kuchokera ku adsorbent.The reverse depressurization desorbed gasi amalowa mu tank gasi buffer tank ndikusakaniza ndi kuyeretsa kukonzanso mpweya.
(5) Kutsuka
Pambuyo n'zosiyana depressurization ndondomeko, kuti apeze kusinthika wathunthu wa adsorbent, ntchito wa haidrojeni wa pathwise kuthamanga kumasulidwa mpweya bafa thanki pa chokhwima malangizo a adsorption kusamba wosanjikiza bedi, kuchepetsa kupanikizika kwa fractional, ndi adsorbent akhoza kwathunthu. kupangidwanso, njirayi iyenera kukhala yodekha komanso yokhazikika kuti zotsatira zabwino za kubadwanso zitsimikizidwe.Kuyeretsa gasi wokonzanso kumalowanso m'thanki ya blowdown tail buffer tank.Kenako idzatumizidwa kunja kwa malire a batri ndikugwiritsidwa ntchito ngati gasi wamafuta.
(6)Equal Repressurization
Pambuyo poyeretsa njira yokonzanso, gwiritsani ntchito kuthamanga kwapamwamba kwa H2 kuchokera ku nsanja ina ya adsorption kuti muchepetsenso nsanja ya adsorption nayenso, ndondomekoyi ikugwirizana ndi ndondomeko yofanana ndi depressurization, sikuti ndi njira yokhayo yowonjezera mphamvu, komanso njira yobwezeretsanso H2. mu bedi danga lakufa la nsanja ina ya adsorption.Njirayi imaphatikizapo kangapo pamtsinje woponderezedwa wofanana.
(7) Mankhwala Gasi Final Repressurization
Pambuyo kangapo kofanana ndi njira zopondereza, kuti musinthe nsanja ya adsorption kupita ku sitepe yotsatira ya adsorption pang'onopang'ono ndikuwonetsetsa kuti chiyero cha mankhwala chisasunthike, chiyenera kugwiritsa ntchito mankhwala a H2 ndi mphamvu yowongolera valavu kukweza kukakamiza kwa nsanja ya adsorption kuti ikhale yothamanga. pang'onopang'ono komanso mokhazikika.
Pambuyo pa ndondomekoyi, nsanja za adsorption zimamaliza kuzungulira kwa "adsorption-generation", ndikukonzekera kulengeza kotsatira.
