Incamake y'umushinga
Sitasiyo ya mbere yo kuvugurura gazi ya LNG muri Nijeriya yatangijwe neza mu gace k’inganda gakomeye, ibi bikaba ari ikimenyetso cy’uko igihugu cyinjiye ku mugaragaro mu cyiciro gishya cyo gukoresha neza gazi karemano mu bikorwa remezo by’ingufu. Iyi sitasiyo ikoresha ikoranabuhanga rinini ryo gushyushya umwuka mu kirere, aho ubushobozi bwo gutunganya buri munsi burenga metero kibe 500.000. Binyuze mu gukoresha ubushyuhe karemano n’umwuka wo mu kirere kugira ngo hatabaho gukoresha ingufu, itanga igisubizo gihamye, gihendutse kandi gitanga ingufu nke zisukuye ku bushobozi bw’ingufu mu nganda no mu ngo.

Ibicuruzwa by'ingenzi n'ibiranga tekiniki

1. Sisitemu nini cyane yo gukamura umwuka ushyushye mu kirere
   Imbere muri sitasiyo hagizwe n'imirongo myinshi ihuza ibyuma binini bitanga umwuka ushyushye, bifite ubushobozi bwo gushyushya ikirere bwa 15.000 Nm³/h. Ibi bikoresho bitanga umwuka bigizwe n'imiterere y'imiyoboro y'amazi ifite uburenganzira bwo gukora neza cyane hamwe n'igishushanyo mbonera cy'imiyoboro y'umwuka ifite imiyoboro myinshi, byongera ubuso bwo guhanahana ubushyuhe ku kigero cya 40% ugereranije n'uburyo busanzwe. Ibi byemeza ko ubushyuhe bushobora koroherezwa neza ndetse no mu bushyuhe bwinshi. Sitasiyo yose ishobora kugera ku mikorere ijyanye n'igihe iri hagati ya 30% na 110%.
2. Gushimangira uburyo bwo guhangana n'imihindagurikire y'ibidukikije mu byiciro bitatu
   Yakozwe by'umwihariko kugira ngo ikoreshwe mu gihe cy'ubushyuhe bwinshi, ubushuhe bwinshi, n'umunyu mwinshi wo mu bwoko bwa spray: Sisitemu yo Gutunganya Ubwiza no Gutunganya Umutwaro Ihujwe na algorithme zo kumenya ubushyuhe bw'ikirere no guhanura umutwaro, sisitemu yo kugenzura ihindura mu buryo bwikora umubare w'ibikoresho bikoresha umuyaga n'uburyo bikwirakwira mu mutwaro hashingiwe ku bushyuhe, ubushuhe, n'ibikenewe mu gihe nyacyo cya gazi. Binyuze mu ngamba zo kugenzura ubushyuhe n'umuvuduko w'ibice byinshi, ikomeza ihindagurika ry'ubushyuhe bwa gazi karemano muri ± 3°C n'ubuziranenge bwo kugenzura umuvuduko muri ± 0.5%, igera ku byuzuye ibisabwa bikomeye n'inganda ku bipimo by'itangwa rya gazi.
   • Urwego rw'ibikoresho: Ingufu za Vaporizer zubatswe mu byuma byihariye bya aluminiyumu birwanya ingese, hamwe n'ibice by'ingenzi by'imiterere bivurwa n'ingufu zikomeye zirwanya ingese.
   • Urwego rw'imiterere: Intera nziza hagati y'amababa n'imiyoboro y'umwuka birinda kwangirika kw'imikorere bitewe n'ubushyuhe bwinshi mu bidukikije.
   • Urwego rwa Sisitemu: Ifite uburyo bwo gukurura amazi bukoresheje ubwenge butuma amazi ahinduka kandi agashonga kugira ngo ikore neza mu bihe byose by'ikirere ngarukamwaka.
3. Urubuga rwuzuye rw’imicungire y’umutekano n’ingufu rukoreshwa mu buryo bwuzuye
   Hashyizweho sisitemu yo kurinda umutekano ifite ibyiciro bine: Gukurikirana ibidukikije → Guhuza Ibipimo by'Ibikorwa → Kurinda Imiterere y'Ibikoresho → Gusubiza mu buryo bwihutirwa. Sisitemu yemewe na SIL2 (SIS) icunga imiyoboro y'umutekano mu nganda zose. Iyi sisitemu ihuza icyuma gisubiza no gusubizamo umwuka mu buryo bwa Boil-Off Gas (BOG), igenzura ko imyuka ihumanya ikirere igera hafi kuri zeru mu gihe cyose cyo gukwirakwiza umwuka. Urubuga rwo gucunga ingufu rukurikirana imikorere ya buri gice gikwirakwiza umwuka mu buryo bwihuse, bigatuma habaho kubungabunga no kunoza imikorere y'ingufu mu buryo bwuzuye.

Agaciro k'ikoranabuhanga mu guhanga udushya no gushyira mu mwanya w'aho ibintu biherereye
Sisitemu y'ingenzi yo gushyushya umwuka muri uyu mushinga irimo udushya twinshi duhuye n'ikirere cya Afurika y'Iburengerazuba, ikemeza neza uburyo ikoranabuhanga rinini ryo gushyushya umwuka mu kirere mu turere dushyuha tw'inyanja rikora neza kandi rikungahaye ku bukungu bw'ikoranabuhanga rinini ryo gushyushya umwuka mu kirere mu turere dushyuha. Mu gihe cy'ishyirwa mu bikorwa ry'uyu mushinga, ntitwatanze gusa ipaki y'ingenzi, ibikoresho, n'amahugurwa ya tekiniki, ahubwo twanafashije mu gushyiraho urwego rw'imikorere n'uburyo bwo kubungabunga hamwe n'urusobe rw'ibikoresho bisimbura ibindi. Gutangiza sitasiyo ya mbere nini yo kuvugurura umwuka mu kirere muri Nijeriya ntabwo bitanga gusa inkunga y'ikoranabuhanga mu ihindagurika ry'ingufu mu gihugu, ahubwo binatanga icyitegererezo cyiza n'inzira yizewe ya tekiniki yo guteza imbere ibikorwa remezo by'ingufu zisukuye ku rwego runini kandi bihendutse mu bihe nk'ibyo muri Afurika y'Iburengerazuba.
