Izinzuzo Zobuchwepheshe Bokususa I-Iron Oxide
Isingeniso kubuchwepheshe bokususa i-Iron Oxide Desulfurization
Ubuchwepheshe bokususa i-iron oxide dry desulfurization basetshenziswa kusenesikhathi. Ubuchwepheshe bokuqala bokususa i-iron oxide dry desulfurization obusetshenziswa kugesi kwakuwubuchwepheshe bokususa i-iron oxide desulfurization obusebenzisa i-bog iron ore njenge-desulfurizer. Eminyakeni yamuva nje, ikhwalithi ye-iron oxide desulfurizers iye yathuthuka kakhulu.
Indlela eyinhloko yokususa i-iron oxide esulfurization iwukususa i-iron oxide, i-oxidation kanye ne-adsorption. Lapho igesi yokudla equkethe i-H2S idlula embhedeni we-iron oxide, kwenzeka ukusabela kwe-exothermic ngaphansi kwengcindezi evamile futhi i-catalytically oxidized ibe yi-sulfur ions ebusweni be-iron oxide. Umkhiqizo udonswa yi-iron oxide ukuze kufezwe injongo yokususa i-sulfurization.
Ngemva kokusebenza isikhathi esithile, uma indawo yokuphuma yombhoshongo wokususa i-sulfurization iseduze nenani lomklamo, kusho ukuthi ukupakisha kombhoshongo kugcwele futhi kulahlekelwa amandla awo okususa i-sulfurization, futhi kudinga ukushintshwa. Uma ushintsha, vala i-valve yokungena komoya bese uhlanza umbhoshongo wokususa i-sulfurization nge-nitrogen kuze kube yilapho ukuhlolwa kwegesi sekufanelekile, vula imbobo yokuhlanza kanye nembobo yokungenisa umoya ukuze uvuselele ukupakisha. Ngemva kokuvuselela, vula imbobo yokudonsa umoya kanye nembobo yokukhipha umoya ukuze ushintshe ukupakisha.
Inqubo yokusabela kwe-iron oxide desulfurization kanye nokuvuselelwa kabusha imi kanje:
Inqubo yokususa i-sulfurization:
UFe 2 I-THE 3 ·H 2 O+3H 2 S==Fe 2 S 3 ·H 2 O+3 H 2 O+5.2 kcal
Inqubo yokuvuselela
2Fe 2 S 3 ·H 2 O +3 O 2 ==2Fe 2 I-THE 3 ·H 2 O +6S+94.2 kcal
Uma igesi iqukethe i-O2 2 , lapho u-O 2 /H 2 S＞2.5, ukusabela kokuvuselelwa kwe-desulfurization kungafeza ukuvuselelwa okuqhubekayo, ifomula yokusabela engenhla ihlanganiswa ibe:
UFe 2 I-THE 3 ·H 2 I-THE
2H 2 S+ O 2 =========2H 2 O+2S
Ukuvuselelwa kwe-iron oxide desulfurizer kuyinqubo exothermic. Uma ukuvuselelwa kushesha kakhulu futhi ukushisa kukhishwa ngamandla, i-desulfurizer izobamba umlilo kalula futhi ishe. Izinga lokushisa lokuvuselelwa kumele lilawulwe kahle.
Ukucubungula igesi yemvelo inqubo yokususa umhwamuko wamanzi, i-hydrogen sulfide, i-mercaptan, kanye ne-carbon dioxide kugesi yemvelo. Imishini eyinhloko ihlanganisa iyunithi yokuphelelwa amanzi emzimbeni, iyunithi yokususa i-sulfurization, iyunithi yokususa i-carbonization, futhi ukubuyiselwa kwe-hydrocarbon elula iyunithi.
Izinzuzo Zobuchwepheshe Bokususa I-Iron Oxide
(1) Isikhathi sokwakha sifushane kanti utshalomali oluqala kanye nje luncane.
(2) Ukunemba okuphezulu kokukhipha i-sulfurization.
(3) Indawo encane yokugcina umkhondo, esindisa isikhala.
(4) Ubuchwepheshe sebuvuthiwe, ukuthembeka kokusebenza kuphezulu, ukusebenza kulula, futhi izinga lokwehluleka liphansi.
(5) Imishini ilula, izindleko zokulungisa zansuku zonke ziphansi, futhi abasebenzi bayalondolozwa.
(6) I-desulfurizer iphephile kakhulu. I-desulfurizer esetshenziswa ohlelweni ayinabo ubuthi futhi ayinangozi emvelweni nasemzimbeni womuntu, futhi inezinzuzo ezinhle zemvelo.
(7) Ukukwazi ukuhlangabezana nezidingo zikahulumeni wendawo zokukhishwa kwe-hydrogen sulfide.
