Ubuziranenge bwo mu Bushinwa bwohereza ibicuruzwa mu mahanga - PSA decarbonisation skid - Rongteng

Ibisobanuro

Gazi isanzwe ya decarburisation (decarbonisation) skid, nigikoresho cyingenzi mugusukura gaze cyangwa gutunganya.

Ibiri muri karuboni ya dioxyde de gaze ya gaze isanzwe ntigomba kurenza 3%. Dioxyde de carbone mumazi nyuma yicyuma gifite ruswa ikomeye cyane. Niba agaciro ka PH ari kamwe, igipimo cya acide ya dioxyde de carbone nacyo kiri hejuru, bityo urugero rwa ruswa ya dioxyde de carbone ku byuma nayo iri hejuru.

Umuvuduko ukabije wa adsorption (PSA) nubuhanga bushya bukoreshwa mugutandukanya imvange ya gaze mubuhanga bwo gutandukanya adsorption. Ugereranije nuburyo gakondo bwo kwinjiza imiti, tekinoroji ya PSA irashimishije mubukungu mu kuvana no kugarura H2S na CO2 muri gaze gasanzwe, kandi irimo gutezwa imbere cyane.

Ikoranabuhanga rya PSA ritandukanya gazi rifite ibyiza byo gukora byoroheje, gutakaza umuvuduko muke, kubura umwuma mugihe ukuraho CO2, ikime gito cya gaze n'amazi meza, kandi ibicuruzwa birashobora kuzuza ibisabwa byoherezwa hanze. PSA irashobora gukoreshwa muburyo bwa CO2 hamwe no guhitamo desulfurizasi muri gaze gasanzwe.

Imbonerahamwe

Adsorption yakozwe mubitutu naho desorption ikorwa mukigabanuka. Kuberako inzitizi ya adsorption ari ngufi kandi ubushyuhe bwa adsorption ntibushobora gukwirakwira mugihe, burashobora gukoreshwa muri desorption. Kubwibyo, ubushyuhe bwigitanda cya adsorption buterwa nubushyuhe bwa adsorption nubushyuhe bwa desorption ntacyo bihindura, bishobora gufatwa nkibikorwa bya isothermal. Igikorwa kimwe cya adsorption cyigitanda gikora, cyaba ubushyuhe bwa swing adsorption cyangwa igitutu cya swing adsorption, kubera ko adsorbent igomba kuvugururwa, iyamamaza rimwe na rimwe. Mu nganda, ibitanda bibiri cyangwa byinshi bya adsorption bikoreshwa, kugirango adsorption hamwe no kuvugurura uburiri bwa adsorption bikorwa muburyo butandukanye (cyangwa na cycle), kugirango bikomeze inzira yose ya adsorption.

Ibiranga imikorere

Imikorere ya pression swing adsorption decarbonisation skid ni 90% .CO2 irashobora gutandukanywa nimpinduka zumuvuduko hamwe na adsorption yumubiri, nta reaction yimiti. Usibye gukuraho CO2, tekinoroji ya PSA ikoreshwa cyane mugusana no kweza H2, CH4, CO, CO2 nizindi myuka.
