Ukutholwa kwesibabule kusuka kugesi yemvelo kusetshenziswa inqubo ye-LO-CAT

I-Sichuan Hengzhong Clean Energy Equipment Co., Ltd. igxile emkhakheni wegesi ukwelashwa kwekhanda eliphilile, ukuhlanzwa kwegesi yemvelo, Ukubuyiselwa kwe-LPG, Isitshalo se-LNG futhi isethi yejeneretha yegesi yemvelo.

Inqubo yokutakula i-H₂I-S kugesi yemvelo ikhethwa kakhulu ngokusekelwe enanini legesi ene-asidi, i-H ₂ Ukuhlushwa kwe-S, kanye nezidingo zokuhlanza. Njengamanje, izinqubo zezimboni ezisetshenziswa kakhulu zifaka izinhlobo ezimbili ezilandelayo: (1) Inqubo ye-Claus）(2) I-LO-CAT

Manje sethula indlela yokubuyisa isibabule usebenzisa inqubo ye-LO-CAT.

Inqubo yenqubo eyinkimbinkimbi yokususa i-iron sulfurization

Inqubo yokususa i-iron eyinkimbinkimbi iyindlela yokuxova i-iron emanzi esebenzisa i-iron eyinkimbinkimbi njengesihluthulelo sokususa i-hydrogen sulfide. Isici sayo ukuguqula i-H ngqo₂I-S kugesi ibe yi-elemental S. Ngemva kokumuncwa, okuqukethwe yi-H2S kugesi kungaphansi kwama-20ppm. Luhlobo olusha lobuchwepheshe bokususa i-sulfur ngenqubo elula, amandla aphezulu esibabule, kanye nobungane nemvelo futhi obungenabo ubuthi. Izinga lokubuyisa isibabule lifinyelela ku-99.9%, futhi igesi yomsila ehlanziwe ingahlangabezana nezinkomba zemvelo ezithuthuka njalo. Inqubo eyinkimbinkimbi yokususa i-iron ifanele amayunithi okubuyisa isibabule ane-H₂Okuqukethwe kwe-S okungu-0-100% kanye no-0.1-20 t/ngosuku.

Incazelo engcono kakhulu yeyunithi yokubuyisa isulfure yensimbi ehlanganisiwe ngesileyidi isethi eyodwa yesibabule engaphansi kwama-t/ngosuku.

Umdwebo wokugeleza kwenqubo yokubuyiselwa kwesibabule ngendlela eyinkimbinkimbi yensimbi

Ingqikithi yale nqubo isekusebenziseni insimbi e-chelated (Fe³⁺) njengesikhuthazi sokuxuba i-H₂S ngqo ibe yi-elemental sulphur esigabeni soketshezi.

Isigaba Sokumunca: I-H₂Igesi equkethe i-S ingena ku-absorber bese ixhumana nesisombululo se-catalyst.³⁺ i-oxidizes H₂I-S ibe yisibabule esiyisisekelo ngenkathi incishiswa ibe yinsimbi yensimbi (i-Fe²⁺).

Isigaba Sokuvuselelwa: Isixazululo esiqukethe i-Fe²⁺ ingena ku-oxidizer. Ngokuvuthela emoyeni, i-Fe²⁺ ibuyiselwa ku-Fe³⁺, ukubuyisela umsebenzi wesisombululo ukuze sisetshenziswe ngokujikeleza.

Ukubuyiselwa Kwesibabule: I-slurry yesibabule ekhiqizwe ihlukaniswa ngemishini efana nezihlungi ze-vacuum ukuze ekugcineni kwakheke amakhekhe esibabule.
