Iyunithi yokukhiqiza igesi yemvelo engama-500kg

Inqubo yezobuchwepheshe

Ukucindezelwa kwegesi yemvelo nokuguqulwa

Igesi yemvelo engaphandle komkhawulo webhethri iqala ngokucindezelwa ibe ngu-1.6Mpa yi-compressor, bese ishiselwa cishe ku-380 ℃ yi-feed gas preheater engxenyeni yokuguquguquka kwesithando somlilo esishintshashintshayo, bese ingena ku-desulfurizer ukuze ikhiphe isulfure kugesi ophakelayo. ngaphansi kwe-0.1ppm. Igesi yokuphakelwa kwe-desulfurized kanye nomusi wokucubungula (3.0mpaa) Lungisa i-heater yegesi exubile ngokwevelu ezenzakalelayo ye-H2O / ∑ C = 3 ~ 4, uqhubeke ushisa ngaphambili ube ngaphezu kuka-510 ℃, bese ufaka ngokulinganayo ipayipi lokuguqula elisuka endaweni eqoqwayo yegesi ephezulu. ipayipi elikhulu kanye nepayipi le-pigtail ephezulu. Kusendlalelo se-catalyst, i-methane isabela ngesitimu ukuze ikhiqize i-CO ne-H2. Ukushisa okudingekayo ekuguquleni i-methane kunikezwa ingxube kaphethiloli eshiswe endaweni yokushisa engezansi. Izinga lokushisa legesi eliguquliwe eliphuma esithandweni senguquko lingu-850 ℃, futhi izinga lokushisa eliphezulu liguqulwa libe izinga lokushisa eliphezulu. Igesi yamakhemikhali ingena ohlangothini lweshubhu kubhayela wokushisa imfucuza ukukhiqiza umusi ogcwele u-3.0mpaa. Izinga lokushisa legesi eliguqukayo elisuka kubhayela wokushisa imfucumfucu lehla liye ku-300 ℃, bese igesi yokuguqula ingena ku-heater yamanzi okuphakelayo ku-boiler, i-conversion gas water cooler kanye ne-conversion gas water separator yona ukuze ihlukanise i-condensate ne-condensate yenqubo, igesi yenqubo ithunyelwa ku-PSA.

Igesi yemvelo njengophethiloli ixutshaniswa negesi ye-press swing adsorption desorption, bese ivolumu yegesi kaphethiloli ingena kusifudumezi segesi kaphethiloli ilungiswa ngokuya ngezinga lokushisa legesi lapho kuphuma isithando somlilo esishintshashintshayo. Ngemva kokulungiswa kokugeleza, igesi kaphethiloli ingena endaweni yokushisa ephezulu ukuze ivuthe ukuze inikeze ukushisa esithandweni senguquko.

Amanzi ancibilikisiwe ashiswa kuqala yi-preheater yamanzi ancibilikisiwe kanye ne-boiler feed water preheater futhi angena ku-steam yomkhiqizo we-flue gas waste boiler kanye nokulungisa kabusha i-gas waste boiler.

Ukuze wenze amanzi okuphakela kubhayela ahlangabezane nezidingo, inani elincane lesisombululo se-phosphate kanye ne-deoxidizer ukuze kuthuthukiswe ukukala nokugqwala kwamanzi abhayela. Isigubhu kufanele siqhubeke sikhipha ingxenye yamanzi akubhayela ukulawula ingqikithi yezinto eziqinile ezincibilikisiwe zamanzi abhayela esigubhu.

I-adsorption ye-pressure swing

I-PSA iqukethe imibhoshongo emihlanu ye-adsorption. Umbhoshongo owodwa we-adsorption usesimweni sokukhangisa noma kunini. Izingxenye ezifana ne-methane, i-carbon dioxide ne-carbon monoxide ku-conversion gas zihlala phezu kwe-adsorbent. I-Hydrogen iqoqwa phezulu kombhoshongo we-adsorption njengezingxenye ezingezona i-adsorption futhi ithunyelwa ngaphandle komngcele. I-adsorbent egcwele izingxenye zokungcola ikhishwa ku-adsorbent ngesinyathelo sokwenziwa kabusha. Ngemva kokuqoqwa, ithunyelwa esithandweni sokuvuselela kabusha njengophethiloli. Izinyathelo zokuvuselelwa kombhoshongo we-adsorption zenziwe ngezinyathelo eziyi-12: ukwehla komfaniswano wokuqala, ukwehla komfaniswano wesibili, ukwehla kweyunifomu yesithathu, ukukhishwa okuya phambili, ukukhishwa okuhlehlayo, ukushaywa, ukukhuphuka komfaniswano wesithathu, ukukhuphuka kweyunifomu yesibili, ukukhuphuka komfaniswano wokuqala nokukhuphuka kokugcina. Ngemuva kokwakhiwa kabusha, umbhoshongo we-adsorption usuyakwazi ukwelapha igesi eguquliwe futhi ukhiqize i-hydrogen. Imibhoshongo emihlanu ye-adsorption iyashintshana ukwenza lezi zinyathelo ezingenhla ukuqinisekisa ukwelashwa okuqhubekayo. Inhloso yokuguqula igesi nokukhiqiza i-hydrogen ngokuqhubekayo ngesikhathi esifanayo.
