Huina hoʻomaʻemaʻe kinoea hydrogen sulfide

Hoʻolauna

Me ka hoʻomohala ʻana o ko mākou kaiāulu, kākoʻo mākou i ka ikehu maʻemaʻe, no laila ke piʻi nui nei ke koi no ke kinoea kūlohelohe e like me ka ikehu maʻemaʻe. Eia nō naʻe, i ke kaʻina hana o ka hoʻohana kinoea maoli, nui nā pūnāwai kinoea i loaʻa pinepine i ka hydrogen sulfide, kahi e hoʻopōʻino ai nā mea hana a me nā pipeline, hoʻohaumia i ke kaiapuni a hoʻoweliweli i ke olakino kanaka. Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ʻo ka hoʻohana ākea o ka ʻenehana desulfurization kūlohelohe i hoʻoponopono i kēia mau pilikia, akā i ka manawa like, ua hoʻonui ʻia ke kumukūʻai o ka hoʻomaʻemaʻe kinoea maoli a me ka mālama ʻana.

Kumukānāwai

ʻO ka molecular sieve desulphurization (i kapa ʻia hoʻi ka desulfurization) skid, i kapa ʻia hoʻi ka molecular sieve sweeting skid, he mea nui i ka hoʻomaʻemaʻe kinoea maoli a i ʻole ka papahana hoʻomaʻemaʻe kinoea kūlohelohe.

ʻO ka sieve molecular kahi aniani metala aluminosilicate alkali me ke ʻano iwi a me ke ʻano microporous like ʻole. He adsorbent me ka hana maikaʻi loa, ka mana adsorption kiʻekiʻe a me ka koho adsorption. ʻO ka mea mua, he nui nā kahawai me ka nui o ka pore a me nā puka i hoʻonohonoho pono ʻia i loko o ka molecular sieve structure, ʻaʻole ia e hāʻawi wale i kahi ʻāpana nui loa, akā e kaupalena ʻia ke komo ʻana o nā molekala nui ma mua o nā lua; ʻO ka lua, he polarity kiʻekiʻe ka ʻili o ka molecular sieve ma muli o nā hiʻohiʻona o ka lattice ionic, no laila he kiʻekiʻe adsorption hiki no nā molekole unsaturated, polar molela a me nā molekole polarizable. ʻO ka wai a me ka hydrogen sulfide nā molekole polar, a ʻoi aku ka liʻiliʻi o ke anawaena mole ma mua o ke anawaena pore o ka sieve molecular. I ka wā e hele ai ke kinoea maka i loko o ka mole mole sieve moena i ka lumi wela, e hoʻopili ʻia ka wai a me ka hydrogen sulfide, no laila, ua hoʻemi ʻia ka ʻike o ka wai a me ka hydrogen sulfide i loko o ke kinoea hānai, a ʻike ʻia ke kumu o ka dehydration a me ka desulfurization. ʻO ke kaʻina hana adsorption o ka molecular sieve e pili ana i ka condensation capillary a me ka adsorption kino i hana ʻia e ka ikaika van der Waals. E like me ka hoʻohālikelike Kelvin, hoʻemi ʻia ka condensation capillary me ka piʻi ʻana o ka mahana, ʻoiai ʻo ka adsorption kino he kaʻina exothermic, a ua emi kona adsorption me ka piʻi ʻana o ka mahana. a piʻi me ka piʻi ʻana o ke kaomi; No laila, ke kaʻina hana adsorption o ka molecular sieve e hana maʻamau i ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe kiʻekiʻe, ʻoiai ka hana analytical regeneration e lawe ʻia ma ke kiʻekiʻe wela a me ka hoʻohaʻahaʻa kaomi. Ma lalo o ka hana o ke kiʻekiʻe wela, maʻemaʻe a me ka haʻahaʻa puʻe regeneration kinoea, ka molecular sieve adsorbent hoʻokuʻu i ka adsorbate i loko o ka micropore i loko o ka regeneration kinoea kahe a hiki i ka nui o ka adsorbate i ka adsorbent hiki i kahi haʻahaʻa loa. Loaʻa iā ia ka hiki ke adsorb i ka wai a me ka hydrogen sulfide mai ke kinoea hānai, e ʻike i ke kaʻina hana hou a me ka hana hou ʻana o ka sieve.

Kaʻina hana ʻenehana

Hōʻike ʻia ke kahe kaʻina hana ma ke kiʻikuhi. Hoʻohana ka ʻāpana i ʻekolu kaʻina hale kiaʻi, hoʻokahi hale kiaʻi no ka adsorption, hoʻokahi hale kiaʻi no ka hoʻoulu hou ʻana a me hoʻokahi hale kiaʻi no ka hoʻoluʻu. ka coalescence separator, a laila komo i ka molecular sieve desulfurization hale kiaʻi a-801, a-802 a me a-803. ʻO ka wai a me ka hydrogen sulfide i loko o ke kinoea hānai e adsorbed e ka molecular sieve e hoʻomaopopo i ka dehydration a me ka hydrogen sulfide adsorption process.The hoʻomaʻemaʻe kinoea no ka dehydration a me ka hydrogen sulfide removal komo i ka huahana kinoea lepo kānana e wehe i ka molecular sieve lepo a lawe ʻia e like me. kinoea huahana.

Molecular kānana pono regeneration ma hope o adsorbing i kekahi nui o ka wai a me ka hydrogen sulfide.Part o ke kinoea huahana ua alakai mai i ke kinoea huahana ma hope o ka lepo kānana e like me ka regeneration kinoea. Ma hope o ka hoʻomehana ʻana o ke kinoea i 270 ℃ i ka umu wela, ua hoʻomehana ʻia ka hale kiaʻi i 270 ℃ mai luna a lalo ma o ka molecular sieve desulfurization hale kiaʻi i hoʻopau i ke kaʻina adsorption, i hoʻopili ʻia ka wai a me ka hydrogen sulfide ma ka molecular sieve hiki ke hoʻoholo e lilo i kinoea hoʻohou waiwai a hoʻopau i ke kaʻina hana hou.

ʻO ke kinoea hoʻohou waiwai ma hope o ka haʻalele ʻana i ka hale kiaʻi hou e komo i ka condenser kinoea regeneration e hoʻomaʻalili ʻia a hiki i kahi 50 ℃, a maloʻo ke kinoea a hāʻawi ʻia i ke poʻo flare.

Pono ka halekiai sieve molecular e hoʻomaʻalili ma hope o ka hana hou ʻana. I mea e ho'ōla hou ai a hoʻohana i ka ikehu wela, hoʻohana mua ʻia ke kinoea regeneration e like me ke kinoea puhi anuanu, a hoʻomaha ʻia ka hale kiaʻi ma kahi o 50 ℃ mai luna a lalo ma o ka molecular sieve desulfurization hale kiaʻi i hoʻopau i ke kaʻina hana hou. I ka manawa like, ua preheated ia iho. Ma hope o ka puka ʻana o ke kinoea puhi anuanu i ka hale hoʻoluʻu, komo ia i ka umu hoʻomehana ʻana o ke kinoea hou no ka hoʻomehana ʻana, a laila hoʻolaʻa hou i ka hale kiaʻi molecular sieve desulfurization e like me ka lean regeneration gas. Hoʻololi ka mea hana i kēlā me kēia 8 hola.
