Ifektri yaseShayina yesakhiwo esihlanganisiwe saseShayina esishintshwa ngokuphelele ngokushisa kwepuleti esetshenziswa ku-Ngl Fractionation,
Ukususwa kwe-Shayina kwe-Sulphurization Yokukhiqizwa kwe-Hydrogen, Ukuhlanzwa kwegesi ye-Coke Oven,

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.

Izici zedivayisi

Umklamo ojwayelekile ofakwe kuma-skid ushintsha imodi yendabuko yokufaka endaweni. Ngokucutshungulwa, ukukhiqiza, ukufaka amapayipi kanye nokwakheka kwama-skid enkampanini, ukulawulwa kokukhiqizwa kwenqubo yonke kwezinto, ukutholwa kwamaphutha kanye nokuhlolwa kwengcindezi enkampanini kufezeka ngokugcwele, okuxazulula ngokuyisisekelo ingozi yokulawula ikhwalithi ebangelwa ukwakhiwa komsebenzisi endaweni, futhi kufeza ngempela ukulawulwa kwekhwalithi yenqubo yonke.

Yonke imikhiqizo ifakwe ama-skid enkampanini. Umqondo wokukhiqiza efektri uyamukelwa. Ngemva kokudlula ekuqinisekisweni kwefektri, iyahlukaniswa ngokwesimiso sokuhlukaniswa esimisiwe bese ithunyelwa endaweni yomsebenzisi ukuze ihlanganiswe kabusha. Umthamo wokwakha endaweni uncane futhi umjikelezo wokwakha umfushane.

Izinga lokuzenzakalela liphezulu kakhulu. Ukusebenza kwedivayisi kungaqashwa ngokuzenzakalelayo futhi kulawulwe ngohlelo oluphezulu, futhi idatha ebalulekile ingalayishwa kuseva yamafu ngesikhathi sangempela ukuze kutholakale kude, ukuze kufezwe ukuphathwa okungenamuntu endaweni.

Ukuhamba kwedivayisi kunamandla kakhulu. Ngokwesimo esithile sephrojekthi, idivayisi ingathuthelwa kwenye indawo futhi isetshenziswe ngemva kokuskenwa futhi, ukuze kutholakale ukusetshenziswa kabusha kwemishini futhi kuqinisekiswe inzuzo ephezulu yenani lemishini.

Ngokwesidingo se-hydrogen sesiteshi se-hydrogenation, yenza ukwakheka kwenqubo ejwayelekile kanye nomgomo wokuklama wokuhlanganisa ngokwemodyuli yenqubo ukuze kufezwe ukukhiqizwa okujwayelekile kwemikhiqizo bese kwakha imikhiqizo yochungechunge olujwayelekile, olulungele ukuphathwa kwemishini yomsebenzisi, izingxenye ezivamile zokuphumula futhi kuncishiswe izindleko zokusebenza kweyunithi.

Ngamafuphi, iyunithi yokukhiqiza i-hydrogen efakwe kuma-skid gas iwumthombo we-hydrogen ofaneleka kakhulu wokusebenza kwesiteshi se-hydrogenation esikhathini esizayo.

Iyunithi yokususa i-nitrogen egesini yemvelo isusa i-nitrogen egesini yemvelo ukuze ilungiselele ukudluliselwa kwepayipi. Ngokusho kwedatha ye-Natural Gas Research Institute, ama-17% egesi yemvelo egcinwe e-United States aqukethe okuqukethwe okuphezulu kwe-nitrogen. Izindinganiso eziningi zamapayipi zidinga ukuthi okuqukethwe kwe-nitrogen egesini yemvelo kube ngaphansi kuka-4%. Igesi yemvelo ene-nitrogen eningi ivalekile ngoba ayikwazi ukuthunyelwa emakethe ngamapayipi. Uma kune-nitrogen eningi kakhulu epayipini, kunengozi yokuxhuma igesi noma ukusha okubi. I-nitrogen iphinde inciphise inani lama-calorie egesi, okuholela ekwehleni kwe-BTU kanye nenani layo.
Ngenxa yokuthi i-nitrogen (N2) kanye ne-methane (CH4) zinobukhulu obufanayo bama-molecule kanye nama-dielectric constant aphansi, kanye nokuntuleka kwe-reactivity ekhethiwe, njenge-carbon dioxide noma i-hydrogen sulfide kuma-amine units, i-denitrification iyinkimbinkimbi yokuhlukanisa ubuchwepheshe.
