Iyunithi yokukhiqiza i-hydrogen yegesi yemvelo engama-500kg

Inqubo yobuchwepheshe

Ukucindezelwa nokuguqulwa kwegesi yemvelo

Igesi yemvelo engaphandle komkhawulo webhethri iqala icindezelwe ibe yi-1.6Mpa yi-compressor, bese ishiswa ibe cishe yi-380 ℃ yi-preheater yegesi yokuphakelayo esigabeni sokuxhumanisa sesithando sokuguqula umusi, bese ingena kwi-desulfurizer ukuze isuse isibabule kugesi yokuphakelayo engaphansi kuka-0.1ppm. Igesi yokuphakelayo ekhishwe isibabule kanye nomusi wenqubo (3.0mpaa) Lungisa i-preheater yegesi exubile ngokwenani elizenzakalelayo le-H2O / ∑ C = 3 ~ 4, bese ushisisa kusengaphambili kube ngaphezu kuka-510 ℃, bese ungena ngokulinganayo epayipini lokuguqula kusukela epayipini eliyinhloko lokuqoqa igesi eliphezulu kanye nepayipi elingaphezulu le-pigtail. Engqimbeni ye-catalyst, i-methane isabela ngomusi ukuze ikhiqize i-CO ne-H2. Ukushisa okudingekayo ekuguqulweni kwe-methane kunikezwa yingxube kaphethiloli eshiswa esitobhini esingezansi. Izinga lokushisa legesi eguquliwe eliphuma esitobhini sokuguqula lingu-850 ℃, futhi izinga lokushisa eliphezulu liguqulwa libe izinga lokushisa eliphezulu. Igesi yamakhemikhali ingena ohlangothini lweshubhu lebhoyila yokushisa engcolile ukuze ikhiqize umusi ogcwele ongu-3.0mpaa. Izinga lokushisa legesi yokuguqula kusuka kubhoyila yokushisa elahliwe lehla laya ku-300 ℃, bese igesi yokuguqula ingena ku-preheater yamanzi okuphakelwa kwebhoyila, i-conversion gas water cooler kanye ne-conversion gas water separator ukuze ihlukanise i-condensate ne-process condensate, bese igesi yenqubo ithunyelwa ku-PSA.

Igesi yemvelo njengophethiloli ixutshwa negesi yokudonswa kwe-pressure swing adsorption, bese ivolumu yegesi kaphethiloli e-preheater yegesi kaphethiloli ilungiswa ngokuya ngokushisa kwegesi lapho kuphuma khona isithando sokulungisa. Ngemva kokulungiswa kokugeleza, igesi kaphethiloli ingena esitobhini esiphezulu ukuze ishiswe ukuze inikeze ukushisa esithandweni sokulungisa.

Amanzi akhishwe usawoti ashiswa yi-preheater yamanzi akhishwe usawoti kanye ne-boiler feed water preheater bese engena emsikeni we-ex-product we-flue gas waste boiler kanye ne-reforming gas waste boiler.

Ukuze amanzi okuphakelwa kwebhoyila ahlangabezane nezidingo, inani elincane lesisombululo se-phosphate kanye ne-deoxidizer kuzofakwa ukuze kuthuthukiswe ukukalwa nokugqwala kwamanzi ebhoyila. Ibhoyila kufanele ichithe njalo ingxenye yamanzi ebhoyila ukulawula inani eliphelele lamanzi ebhoyila ancibilikisiwe ebhoyila.

Ukumuncwa kwengcindezi yokushintshashintsha

I-PSA inemibhoshongo emihlanu yokumunca. Umbhoshongo owodwa wokumunca usesimweni sokumunca nganoma yisiphi isikhathi. Izakhi ezifana ne-methane, i-carbon dioxide kanye ne-carbon monoxide kugesi yokuguqulwa zihlala phezu kwe-adsorbent. I-hydrogen iqoqwa kusukela phezulu kombhoshongo wokumunca njengezakhi ezingezona ezimuncayo bese ithunyelwa ngaphandle komngcele. I-adsorbent egcwele izingxenye zokungcola ikhishwa ku-adsorbent ngesinyathelo sokuvuselela. Ngemva kokuqoqwa, ithunyelwa esithandweni sokulungisa njengophethiloli. Izinyathelo zokuvuselela zombhoshongo wokumunca zakhiwe ngezinyathelo ezingu-12: ukuwa kokuqala okufanayo, ukuwa kwesibili okufanayo, ukuwa kwesithathu okufanayo, ukukhishwa kwangaphambili, ukukhishwa okuphambene, ukuhlanza, ukuphakama kwesithathu okufanayo, ukuphakama kwesibili okufanayo, ukuphakama kokuqala okufanayo kanye nokuphakama kokugcina. Ngemva kokuvuselelwa, umbhoshongo wokumunca uphinde ukwazi ukwelapha igesi eguquliwe futhi ikhiqize i-hydrogen. Imibhoshongo emihlanu yokumunca iyashintshana ukuze yenze lezi zinyathelo ezingenhla ukuqinisekisa ukwelashwa okuqhubekayo. Inhloso yokuguqula igesi nokukhiqiza i-hydrogen njalo ngesikhathi esifanayo.
