Gazi karemano ivanwamo irimo ingano runaka ya gaze ya aside CO2, ishobora guteza ibibazo nko kugabanuka k'agaciro ka karori no kwangirika k'imiyoboro. Kubwibyo, ni ngombwa ko habaho uburyo bwo gukuraho karuboni mbere yo gutwara no gukoresha imiyoboro.
Dukurikije formula y’agaciro ka gaze karemano mu gipimo cy’igihugu (GB/T 11062-2014), dushobora kubara ko 10mol% CO2 izatera kugabanuka kwa gaze karemano ya methane ku kigero cya 9.80% kuri metero kibe. Iyo CO2 ihuye n’umwuka w’amazi kandi ikaba ifite igitutu cy’igice kirenze 207kPa, izatera ingese ikomeye ku bikoresho n’imiyoboro, kandi hagomba gufatwa izindi ngamba zo kurwanya ingese. Kubwibyo, gaze karemano igomba gukurwaho CO2 cyane mbere yo kujyanwa mu miyoboro y’ubucuruzi.
Uburyo bwa MDEA bukoreshwa gukuraho CO2 muri gaze karemano.
Imiterere ya MDEA ya fizikikemike n'amahame yo gukuramo karubone
MDEA, izina rya siyansi N -methyldiethanolamine, ni amazi adafite ibara cyangwa umuhondo muto afite viscous.
Formule ya molekile: CH3N(CH2CH2OH)2,
Aho ubushyuhe bushyuha: 246~249 ℃ /760mmhg; uburemere bwihariye: 1.0425g/ml (20 ℃);
Aho ubukonje bugera: -21 ℃ (ubuziranenge 99%); ubushyuhe: 101Cp (20 ℃);
Bishobora kuvangwa byoroshye n'amazi, etanoli, eteri, nibindi; alkaline nkeya mu mazi; imikorere ya shimi izabaho muri aside karubone dioxyde na hydrogen sulfide gaze, kandi iyo umuvuduko mwinshi, carbon dioxide na hydrogen sulfide gaze biba byinshi. Bityo inzira yose yo kwinjiza ni inzira yo kwinjiza fiziki na shimi.
Amazi akungahaye kuri MDEA nyuma yo kwinjiza sulfide ya hidrojeni na dioxyde de carbone yinjira muri tanki ya flash kugira ngo ihindure umwuka wa flash, hanyuma yoherezwe mu munara wo kuvugurura. Amazi akungahaye arashyuha kandi agashonga hasi ku munara kugira ngo arekure burundu dioxyde de carbone na sulfide ya hidrojeni. Muri icyo gihe, gazi iri hasi ku munara irazamuka kugira ngo ikore ingaruka zo gukuraho amazi akungahaye hejuru y'umunara; bityo inzira yose yo kuvugurura ni inzira yo kuvugurura imiterere n'imiti. Uburyo bwihariye bwa shimi ni ubu bukurikira:
R2R'N + H2S R2R'NH + HS (uburyo bwo guhita ubikora)
R2R'N+CO2+ H2O R2R'NH +HCO3 (gukora buhoro buhoro)
Hengzhong yibanda ku kuvura ibisigazwa by'amazi mu butaka, gutunganya gazi karemano, kugaruza LPG, Uruganda rwa LNG na seti y'imashini itanga gazi karemano.
