Uruganda rwa LNG rwa MMSCFD 3.5~7 n'uruganda rwa LNG rushyirwa ku rukuta

Ibisobanuro:

Gazi karemano yo gushonga, izwi cyane nka LNG, irimo gukurura gaze karemano mu mazi binyuze mu gukonjesha gaze karemano yo mu mazi munsi y’igitutu gisanzwe kugeza kuri - 162 ℃. Gushonga gaze karemano bishobora kuzigama cyane umwanya wo kubika no gutwara, kandi bifite ibyiza byo kuba bifite agaciro ka karori nyinshi, imikorere myiza, bifasha mu kuringaniza imitwaro yo mu mijyi, bifasha mu kurengera ibidukikije, bigabanya ihumana ry’imijyi n’ibindi.

Gutunganya amazi ni ingenzi mu gukora LNG. Kuri ubu, inzira zo gutunganya amazi zirimo cyane cyane inzira yo gutwika amazi mu buryo bwa cascade, inzira yo gutwika amazi mu buryo bwa frigo ivanze n'inzira yo gutwika amazi hakoreshejwe expander.

Uburyo bwo gushonga gaze karemano hakoreshejwe uburyo bwa Cascade bukoresha uburyo butandukanye bwo kubira gaze karemano munsi y’igitutu gisanzwe kugira ngo ugabanye ubushyuhe bwo gukonjesha intambwe ku yindi kugira ngo ugere ku ntego yo gushonga gaze karemano.

Uburyo bwo gukonjesha buvanze (MRC) ni uburyo bukoresha ubwoko burenga butanu bw’ibikoresho bivanze bivanze, nka Hydrocarboni C1 ~ C5 na N2, nk'amazi akora kugira ngo ahume, ahinduke kandi yongere imbaraga buhoro buhoro kugira ngo abone ubushobozi bwo gukonjesha ku rugero rutandukanye rw'ubushyuhe, hanyuma buhoro buhoro akonjesha gaze karemano. Uburyo bwo gukonjesha buvanze bugabanyijemo ubwoko bwinshi butandukanye bw'uburyo bwo gukonjesha.

Uburyo bwo gukamura umwuka hakoreshejwe expander bivuga uburyo bwo gukamura umwuka hakoreshejwe icyuma gikonjesha gishyuha cyane kugira ngo hakonjeshwe ikirere cya Claude hifashishijwe adiabatic turbo expander.

Gahunda y'ibikorwa ikubiyemo ahanini: icyuma gipima umuvuduko w'umwuka ukoreshwa mu kugaburira gazi, icyuma gisukura gazi karemano n'icyuma gisukura gazi karemano, icyuma gikonjesha, icyuma gikonjesha gikonjesha, icyuma gikonjesha gikonjesha, icyuma gikonjesha n'icyuma gipakira LNG.

Gazi karemano yinjira muri sitasiyo ibanza guca mu gice kigenzura umuvuduko n'ibipimo, kigenzura umuvuduko n'ibipimo bya gaze karemano yinjira; Gazi karemano yinjira mu gice gisukura gaze karemano, aho gaze karemano ikurwaho CO2, H2S ikurwaho no kuvurwa umwuma. Gahunda ya MDEA irasabwa mu gukuraho karubone no gukuraho H2S, inzira yo gukuraho umwuma hakoreshejwe uburyo bwa molekile hamwe n'iminara itatu cyangwa inzira yo gukuraho umwuma irasabwa mu gukuraho umwuma; Kandi birasabwa gukoresha BOG yasubiwemo kandi ikandamijwe mu kongera kuvugurura gaze;

Gazi karemano isukuye ishyirwa mu gice cyo gukamura gaze karemano, ikanashyirwa muri firigo ivanze (MRC liquefaction process) isabwa kugira ngo gaze karemano ikame; LNG ikozwe mu mazi irabikwa mu kigega cyo kubikamo, kandi uburyo bwo kubika mu kirere no mu bushyuhe buke busabwa kugira ngo game ibikemo LNG. Ikigega kimwe cyo kubikamo mu bushyuhe buke gifite BG compressor, naho BOG compressor ikoreshwa mu gushyiramo igitutu cya BOG mbere yo kwinjira mu cyuma cyuma cyuma gihindura imiterere, bitewe n'uko imashini ikoresha cryogenic pump ishyirwamo.
