Ubuziranenge bwo mu Bushinwa MDEA Decarburisation Skid yohereza ibicuruzwa hanze - MDEA uburyo bwa decarburisation skid kubikoresho bya gaze gasanzwe - 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 nayo iri hejuru, bityo urugero rwo kwangirika kwa karuboni ya dioxyde de pole nayo iri hejuru.

Kubwibyo rero, kugirango habeho decarburisiyasi ya gaze karemano, birakenewe kugira ingaruka zikomeye zumuriro mugikorwa cya decarburisation, bityo gazi karemano nyuma yo gutunganya ubushyuhe bwikirere ntibikwiranye na gaze ya gaze. Ariko, niba tudasuzumye ibicuruzwa biva muri gaze karubone, ariko tugakoresha uburyo bwo gutandukanya ubushyuhe buke, bizahita biganisha kumikorere ya gaze karubone. Kugeza ubu, gukoresha imiti isanzwe ya decarbonisation irashobora gukora gusa uburyo bwa ammonia alcool.

Imbonerahamwe

Ukurikije ibiranga ikoranabuhanga rya MDEA, hakenewe inzira yo kuvugurura igice kugirango gaze ya gaze karubone. Muri byo, gaze karemano yinjira cyane cyane mumashanyarazi kuva hasi, no guhura numuti wa MDEA kuva hejuru kugeza hasi mumashanyarazi, ariko ibyinshi mubisubizo bya karuboni ya dioxyde de gaze karubone. Gazi isanzwe yatunganijwe itandukanijwe cyane numunara winjiza hanyuma ugakonja, hanyuma ukabura umwuma. MDEA kuva hepfo yumunara winjira ikenera imbaraga kugirango zinjire mu kuvura umwuma, naho igice cyo hejuru cyumunara winjira cyinjira muminara. Nyuma ya decompression, dioxyde de carbone yakiriwe irakemurwa kandi igashyuha hamwe na parike hagati yumunara wo kuvugurura. Gusa murubu buryo hashobora kubaho ubushyuhe bwibisubizo. Nyuma ya MDEA igisubizo kiva hepfo yumunara kimaze gukonjeshwa, igisubizo cyinjira hejuru yo kwinjizwa, kugirango urangize inzira zose zokuzenguruka. Byongeye kandi, kugirango tumenye neza ko igisubizo gishobora gutunganywa kandi kigasukurwa, 15% by igisubizo kirakenewe kugirango gikemuke. Kugirango dukomeze inzira ya decarbonisation ya gaze gasanzwe, sisitemu izavugururwa binyuze mubisubizo.

Ibiranga imikorere

Imikorere ya decarbonisation kuburyo bwa MDEA ni 99%.
Kugirango ukureho dioxyde de carbone (CO2) muri gaze yo kugaburira, igisubizo cyamazi hamwe na alcoine amine nkuko solvent ikora na CO2 muri gaze yo kugaburira. Gutakaza gaze nke no gukoresha ingufu nyinshi. Uburyo bwa alcool amine burashobora kandi gukoreshwa mugukuraho H2S muri gaze yo kugaburira.
