Uko ingano y'ibicuruzwa bya LNG ihinduka bitewe n'imiterere y'isoko, umusaruro wa LNG ugomba guhuzwa n'impinduka z'isoko. Kubwibyo, hakenewe byinshi kugira ngo umutwaro w'umusaruro urusheho gukomera no kubika LNG mu nganda za LNG.
Igenzura ry'umusaruro wa LNG
Amabwiriza ya Mr compressor
Compressor ya MR ni compressor ikoresha centrifugal. Umutwaro wayo ushobora guhindurwa buri gihe hagati ya 50 ~ 100% binyuze mu guhindura igikoresho gifunga valve y'umwuka n'ingufu yo gusubiza ya compressor.
Kugenzura imitwaro ya sisitemu yo kuvura mbere yo kuyikoresha
Umutwaro w’igishushanyo mbonera cy’agace ka gaze gakuraho aside ntugomba kuba munsi ya 100%. Hashingiwe ku kugenzura umuvuduko w’amazi, igikoresho cya sisitemu yo kuvura mbere gishobora guhindurwa buri gihe mu rugero rw’umutwaro ruri hagati ya 50 na 110% kandi cyujuje ubuziranenge bwo kuvura no gusukura mbere.
Ingano yo kugenzura imitwaro y'agasanduku gakonje karimo amazi
Umutwaro w'igishushanyo mbonera cy'agasanduku gakonjesha karimo amazi ntugomba kuba munsi ya 100%. Iyo umutwaro w'igikoresho uhindutse kuva kuri 50% ukagera kuri 100%, icyuma gihindura ubushyuhe n'amavali biri mu gasanduku gakonjesha bishobora gukora neza kandi bigahura neza n'imiterere y'umutwaro uhinduka.
Muri make, ubushobozi bwo gukoresha igikoresho cyose ni 50% ~ 100%. Abakoresha bashobora guhindura umutwaro w'igikoresho muri uru rwego bitewe n'uko ibicuruzwa bigurishwa kugira ngo barusheho kunoza ubukungu bw'imikorere.
Guhindura ubushobozi bwo kubika ikigega cya LNG
Dukurikije umusaruro wa LNG, ingano y'ikigega cyo kubikamo ibintu dutanga ni umusaruro wa LNG w'iminsi icumi, kandi ingano y'ububiko bw'ikigega cyo kubikamo ibintu ishobora gukoreshwa mu gukumira impinduka mu kugurisha.
Impinduka mu miterere y'imyuka ikomoka ku biryo
Impinduka mu miterere y'imyuka ikomoka ku biryo bizazana imbogamizi mu gutunganya no gukoresha amazi mbere yo kuyasukura.
Uburyo bwo gutunganya imyuka ikoreshwa mbere yo kuyitunganya bukorwa ku mpinduka z'ibice byayo
Igisubizo cyo gukuraho karubone
Dukurikije ingano ya dioxyde de carbone iriho, dukoresha uburyo bwa MDEA amine kugira ngo dukure karubone kandi twongere imiterere ya dioxyde de carbone kugeza kuri 3%. Ubunararibonye bwinshi mu by'ubuhanga bwagaragaje ko iyi miterere ishobora guhuza n'impinduka z'ingano ya dioxyde de carbone no gukura dioxyde de carbone ku rugero rwa 50ppm.
Gukuraho hydrocarbon nyinshi
Karuboni nini cyane muri gaze karemano ahanini ni neopentane, benzene, karuboni mbi cyane n'ibice biri hejuru ya hexane byangiza inzira y'agasanduku k'ubukonje. Gahunda yo gukuramo dukoresha ni uburyo bwo kugabanya karuboni mu buryo bwa "activated carbon adsorption" + uburyo bwo kuzura ubushyuhe buke, bukaba ari gahunda y'ubwishingizi bw'intambwe ebyiri n'ebyiri. Ubwa mbere, karuboni mbi cyane nka benzene na karuboni mbi cyane zinyuzwa muri karuboni mbi ku bushyuhe bw'icyumba, hanyuma ibice biremereye biri hejuru ya propane bigahurizwa kuri - 65 ℃, bitashobora gukuraho ibice biremereye gusa muri gaze y'ibiribwa, ahubwo binatandukanya ibice biremereye kugira ngo haboneke karuboni mbi nyinshi nk'umusaruro w'inyongera.
Igisubizo cyo kubura amazi mu mubiri
Ingano y'amazi muri gaze karemano iterwa ahanini n'ubushyuhe n'umuvuduko. Ihindagurika ry'ibindi bice bya gaze yo mu mazi ntabwo rizagira ingaruka zikomeye ku ngano y'amazi. Amafaranga yo gukaraba imiterere arahagije kugira ngo ahuzwe n'ibyo.
Uburyo sisitemu yo gushonga ihinduka mu buryo bw'amazi ikoreshwa mu guhindura ibice
Impinduka mu miterere ya gaze ikoreshwa mu kugaburira imyuka ikomoka ku biryo bizatuma habaho ihinduka ry'ubushyuhe buterwa n'amazi. Mu guhindura neza igipimo cya MR (mixed refrigerant), ihinduka mu miterere ya gaze ikoreshwa mu kugaburira imyuka rishobora guhinduka ku rugero runini.
