Nā Pōmaikaʻi o ka ʻenehana Iron Oxide Desulfurization
Hoʻolauna i ka ʻenehana Iron Oxide Desulfurization
Ua hoʻopili mua ʻia ka ʻenehana desulfurization maloʻo kinoea. ʻO ka ʻenehana desulfurization maloʻo mua loa i hoʻopili ʻia i ke kinoea, ʻo ia ka ʻenehana desulfurization iron oxide e hoʻohana ana i ka bog iron ore ma ke ʻano he desulfurizer. I nā makahiki i hala iho nei, ua holomua nui ka maikaʻi o nā desulfurizers iron oxide.
ʻO ke ʻano nui o ka desulfurization hao oxide ka catalysis, oxidation a me ka adsorption. Ke hele ka kinoea hānai e loaʻa ana ka H2S ma o ka moena hao oxide, hana ʻia kahi hopena exothermic ma lalo o ke kaomi maʻamau a ua oxidized catalytically i nā ion sulfur ma luna o ka ʻili o ka hao oxide. Hoʻopili ʻia ka huahana e ka hao oxide e hoʻokō i ke kumu o ka desulfurization.
Ma hope o ka holo ʻana no kekahi manawa, inā kokoke ka puka o ka hale kiaʻi desulfurization i ka waiwai hoʻolālā, ʻo ia hoʻi ua piha ka ʻūlū o ka hale kiaʻi a nalowale kona hiki ke desulfurization, a pono e hoʻololi ʻia. I ka wā e hoʻololi ai, e pani i ka valve komo ea a hoʻomaʻemaʻe i ka hale kiaʻi desulfurization me ka naikokene a hiki i ka hōʻoia ʻana o ka hoʻāʻo kinoea, e wehe i ka puka hoʻomaʻemaʻe a me ka puka hoʻokuʻu e hana hou i ka ʻūlū. Ma hope o ka hana hou ʻana, e wehe i ka lua lua a me ka lua hoʻokuʻu e hoʻololi i ka ʻūlū.
ʻO ke kaʻina hana hoʻoheheʻe a me ka hana hou ʻana o ka hao oxide penei:
Kaʻina hana desulfurization:
Fe 2 KA 3 ·H 2 ʻO+3H 2 S==Fe 2 S 3 ·H 2 ʻO+3 H 2 O+5.2 kcal
Kaʻina hana hou
2Fe 2 S 3 ·H 2 ʻO +3 ʻO 2 ==2Fe 2 KA 3 ·H 2 O +6S+94.2 kcal
Inā loaʻa ka O i loko o ke kinoea 2 , i ka wā ʻO 2 /H 2 S>2.5, hiki i ka hopena hana hou ʻana o ka desulfurization ke hoʻokō i ka hana hou mau ʻana, ua hui pū ʻia ke ʻano hana ma luna nei i loko o:
Fe 2 KA 3 ·H 2 KA
2H 2 S+ O 2 ==========2H 2 ʻO+2S
He hana exothermic ka hana hou ʻana o ka iron oxide desulfurizer. Inā wikiwiki loa ka hana hou ʻana a hoʻokuʻu ikaika ʻia ka wela, e maʻalahi ka desulfurizer e hopu i ke ahi a ʻā. Pono e kāohi pono ʻia ka mahana o ka hana hou ʻana.
ʻO ka hana ʻana i ke kinoea kūlohelohe ke kaʻina hana o ka wehe ʻana i ka mahu wai, ka hydrogen sulfide, ka mercaptan, a me ke kalapona ʻokikene mai ke kinoea kūlohelohe. ʻO nā lako nui e komo pū ana me ʻāpana hoʻomaloʻo wai, ʻāpana desulfurization, ʻāpana hoʻohemo kalapona, a me ka hoʻōla ʻana o ka hydrocarbon māmā ʻāpana.
Nā Pōmaikaʻi o ka ʻenehana Iron Oxide Desulfurization
(1) He pōkole ka manawa kūkulu a he liʻiliʻi ka hoʻopukapuka manawa hoʻokahi.
(2) Kiʻekiʻe ka pololei o ka desulfurization.
(3) Kapuahi liʻiliʻi, mālama i kahi.
(4) Ua oʻo ka ʻenehana, kiʻekiʻe ka hilinaʻi o ka hana, maʻalahi ka hana, a haʻahaʻa ka helu hāʻule ʻana.
(5) He maʻalahi nā lako, haʻahaʻa ke kumukūʻai mālama i kēlā me kēia lā, a mālama ʻia ka hana kanaka.
(6) Palekana loa ka desulfurizer. ʻAʻohe mea ʻawahia a ʻino ʻole ka desulfurizer i hoʻohana ʻia i loko o ka ʻōnaehana i ke kaiapuni a me ke kino kanaka, a he mau pono maikaʻi kona no ke kaiapuni.
(7) Hiki ke hoʻokō i nā koi o ke aupuni kūloko no nā hoʻokuʻu hydrogen sulfide.
