Wae purenga hau hauwai sulfide wahie

Kupu Whakataki

Na te whanaketanga o to taatau hapori, ka tohe matou i te kaha ma, no reira kei te piki haere te tono mo te hau maaori hei hiko ma. Heoi, i roto i nga mahi whakangao hau maori, he maha nga puna hau kei roto i te hauwai sulfide, ka pirau nga taputapu me nga paipa, ka whakapoke i te taiao, ka whakararu i te hauora o te tangata. Na te whakawhanaketanga o te aoiao me te hangarau, Ko te whakamahinga whanui o te hangarau desulfurization hau maori kua whakatauhia enei raru, engari i te wa ano, kua piki ake te utu mo te purenga hau me te maimoatanga.

Tikanga

Ko te whakakorenga molecular sieve desulfurization (e kiia ana ko te desulfurization) ko te molecular sieve sweeting skid, he taputapu matua i roto i te mahi horoi hau maori, kaupapa whakamahana hau maori ranei.

Ko te tatari molecular he karaihe aluminosilicate whakarewa alkali me te hanganga anga me te hanganga microporous rite. Ko te adsorbent ki te mahi pai, kaha adsorption teitei me te whiriwhiringa adsorption. Tuatahi, he maha nga hongere me te rahi o te pore rite me nga kohao kua oti te whakarite i roto i te hanganga tatari ngota, ehara i te mea he nui noa te mata o te mata, engari ka whakawhäitihia te urunga o nga ngota ngota nui ake i nga rua; Tuarua, te mata o te tatari rāpoi he polarity tiketike e tika ana ki te āhuatanga o te kurupae katote, no reira he kaha adsorption tiketike mō ngā rāpoi ngota haunga, rāpoi ngota polar me ngā rāpoi ngota polarizable. Ko te wai me te hauwai sulfide he ngota ngota polar, a he iti ake te diameter ngota i te diameter pore o te tatari ngota. A, no te te hau mata kei roto wahi te wai haere i roto i te moenga tatari rāpoi i te pāmahana rūma, te wai tohu me te hauwai sulfide e whenumi, Na, kua heke te ihirangi o te wai me te hauwai sulfide i roto i te hau whāngai, me te kaupapa o te maroketanga me te desulfurization te ite. Ko te tukanga adsorption o te tatari rāpoi ko te condensation capillary me te adsorption tinana na te kaha o van der Waals .E ai ki te wharite Kelvin, ka heke te condensation capillary i te pikinga o te pāmahana, ko te adsorption tinana he tukanga exothermic, a ka heke tona adsorption ki te piki o te pāmahana ka piki ake i te pikinga o te pehanga; Na reira, ko te tukanga adsorption o te tatari molecular i te nuinga o te waa ka mahia i te iti o te pāmahana me te pehanga teitei, i te wa e mahia ana te whakahoutanga tātaritanga i te pāmahana teitei me te iti o te pehanga. I raro i te mahi o te teitei o te wera, te ma me te iti o te hau o te whakahou, ka tukuna e te molecular sieve adsorbent te adsorbate i roto i te micropore ki roto i te rere o te hau whakahou kia tae ra ano te nui o te adsorbate i roto i te adsorbent ki te taumata tino iti. Kei a ia ano te kaha ki te whakauru i te wai me te hauwai sulfide mai i te hau whangai, me te mohio ki te whakahou me te mahi hangarua o te tatari.

Te tukanga hangarau

Ka whakaatuhia te rere o te tukanga ki te hoahoa. Ko te waeine e tango ana i nga tukanga pourewa e toru, kotahi te pourewa mo te adsorption, kotahi te pourewa mo te whakahou me te kotahi pourewa mo te whakamatao. Ka uru te hau kai ki roto i te waahanga, ka heke te pāmahana o te hau whangai e te waeine precooling, katahi ka tangohia te wai kore utu e te whakawehe coalescence, a ka tomo ki te molecular sieve desulfurization pourewa a-801, a-802 me a-803. Ko te wai me te hauwai sulfide i roto i te hau whangai e adsorbed i te tatari rāpoi ki te ite i te dehydration me te hauwai sulfide adsorption process.The hau para mo te whakamaroke me te hauwai sulfide tango tomo te hua tātari puehu hau ki te tango i te puehu tatari rāpoi me te kaweake hei hau hua.

Ko te tatari molecular e hiahia ana ki te whakahou i muri i te whakauru i te nui o te wai me te hauwai sulfide. Ko te wahanga o te hau hua ka arahina mai i te hau hua i muri i te tātari puehu hei hau whakaora. I muri i te wera o te hau ki te 270 ℃ i roto i te oumu whakawera, ka whakawerahia te pourewa ki te 270 ℃ mai i runga ki raro i roto i te molecular sieve desulfurization pourewa kua oti te tukanga adsorption, na te wai me te hauwai sulfide adsorbed i runga i te tatari rāpoi. ka taea te whakatau ki te whai rawa i te hau whakaora me te whakaoti i te mahi whakaora.

Ko te nui o te hau regeneration i muri i te wehenga atu i te pourewa whakaora ka uru ki roto i te condenser hau regeneration kia whakamatao ki te 50 ℃, ka whakamataohia te hau ka tukuna ki te pane mura.

Me whakamatao te pourewa tatari rapoi i muri i te whakaoranga. Hei whakaora me te whakamahi i te kaha o te wera, ka whakamahia tuatahitia te hau regeneration hei hau pupuhi makariri, ka whakamataohia te pourewa ki te 50 ℃ mai i runga ki raro i roto i te pourewa desulfurization molecular sieve kua oti te mahi whakaora. I te wa ano, ka whakamahanahia e ia ano. I muri i te putanga o te hau makariri i te pourewa whakamatao, ka uru ki te oumu whakawera hau whakawera mo te whakamahana, katahi ka whakahou i te pourewa desulfurization rapoi ngota hei hau regeneration hiroki. Ka huri te taputapu ia 8 haora.
