1  Incamake ya Sisitemu

Imyuka ikoreshwa mu gutunganya gazi karemano yinjira mu buryo bwo kuyitunganya mbere y’uko iyungururwa, ikavanwamo, igapimwa umuvuduko wayo hanyuma igapimwa. Nyuma yo gukuraho CO2, CO2 ikoreshwa mu gutunganya gazi karemano.₂, H₂O, hifashishijwe hydrocarbon nyinshi na Hg, yinjira mu gasanduku gakonjesha ka liquefaction, hanyuma igakonjeshwa, igashonga, igakonjeshwa hanyuma igashyirwa mu cyuma gihindura ubushyuhe. Hanyuma yinjira mu kigega cyo kubikamo LNG nk'ibicuruzwa bya LNG.

Uburyo bw'ingenzi bw'ikoranabuhanga bw'iki gikoresho ni ubu:

• Koresha MDEA kugira ngo ukureho dioxyde de carbone;

• Uduce duto tw’ingirabuzimafatizo dukoreshwa mu gukuraho amazir
• Koresha karubone ikora kugira ngo ukureho karubone ziremereye;

• Koresha karubone iterwa na sulfur kugira ngo ukureho mercure;

• Koresha ibintu by'urufunguzo rw'ubuhanga mu kuyungurura urusenda rw'ibinyabutabire n'umukungugu wa karuboni ukoreshwa;

• Gazi karemano yose isukuye irashongeshwa hakoreshejwe uburyo bwa MRC (mixed refrigerant) buzenguruka mu buryo bwo gukonjesha;

  Iyi gahunda ikubiyemo:

• Kuyungurura no gutandukanya imyuka, kugenzura umuvuduko w'amazi n'uburyo bwo gupima;

• Uburyo bwo kuvura mbere y’uko hakorwa isuzuma (harimo gukuramo karubone, amazi mu mubiri, gukuraho hydrocarbon nyinshi, gukuraho mercure, no gukuraho ivumbi);

• Sisitemu yo gupima MR na sisitemu yo gukanda MR;

• Sisitemu yo gukwirakwiza amazi ya LNG;

• Sisitemu ya BOG yo kongera gukoresha ibikoresho

2   Ibisobanuro bya buri sisitemu

2.1      Igice cyo gutandukanya imyuka n'igipimo cyo kugenzura umuvuduko w'umwuka

1) Ibisobanuro by'inzira

Imyuka ituruka mu ruzi rwo hejuru igenzurwa n'umuvuduko hanyuma ikinjira mu cyuma gitandukanya icyuma gitanga imyuka, hanyuma ikinjira mu cyuma cyo hasi nyuma yo gukandamizwa, gutandukana no gupimwa.

Ibikoresho byayo by'ingenzi byo gutunganya ni ugutandukanya icyuma gikoresha umwuka, icyuma gipima ubwiyongere bw'amazi, compressor n'ibindi.

2) Ibipimo by'igishushanyo

Ubushobozi bwo gukoresha: 10×10 ⁴ Nm ³ /umunsi

Ingano yo guhindura: 50% ~ 110%

Umuvuduko w'isoko rya compressor: 5. 2Mpa.g

2.2      Ishami rishinzwe gukuraho aside mu mwuka

1) Ibisobanuro by'inzira

Imyuka ituruka mu mazi yo hejuru yinjira mu gice cyo gukuraho aside, maze iki gice gikoresha uburyo bwa MDEA bwo gukuraho imyuka ikomoka kuri aside nka CO2₂ na H₂S mu mwuka ukoreshwa mu kugaburira.

Gazi karemano yinjira iturutse mu gice cyo hasi cy'umunara wo kwinjiza amazi hanyuma ikanyura mu munara wo kwinjiza amazi kuva hasi kugera hejuru; umuti wa MDEA (amazi yoroheje) winjira uturutse mu gice cyo hejuru cy'umunara wo kwinjiza amazi, ukanyura mu munara wo kwinjiza amazi kuva hejuru kugera hasi, maze umuti wa MDEA na gaze karemano zinyura mu cyerekezo gitandukanye ziba ziri mu munara wo kwinjiza amazi Iyo zihuye neza, CO2₂ muri gaze _ni yinjizwa mu gice cy'amazi, hanyuma ibice bitarahurwa bikurwa hejuru y'umunara wo kwinjizamo umwuka bikinjira mu gikoresho gikonjesha gazi cyakuwemo karubone n'igitandukanya. Gazi isohoka mu gikoresho gitandukanya gazi cyakuwemo karubone yinjira mu gice gikuraho gazi ya mercure, hanyuma condensate ijya mu kigega cya flash.

CO₂ ibikubiye mu bipimo karemano byavuwe biri munsi ya 50ppmv.

MEDA yinjije CO₂ yitwa amazi akungahaye, yoherezwa kuri flash tower, maze gazi karemano isohoka mu gihe hagabanijwe umuvuduko yoherezwa kuri sisitemu ya lisansi. Nyuma yo gucana, amazi akungahaye ahinduranya ubushyuhe n'umuti (amazi make) uva hasi mu munara wo kuvugurura, hanyuma ubushyuhe bukazamuka bukagera kuri ~98 °C kugira ngo ujye mu gice cyo hejuru cy'umunara wo kuvugurura.

Amazi yoroheje ava mu munara wo kuvugurura anyura mu cyuma gishyushya ubushyuhe bw’amazi menshi n’icyuma gikonjesha amazi yoroheje, amazi yoroheje akonjeshwa kugeza kuri ~40°C, kandi nyuma yo gushyirwamo igitutu n’ipompo y’amazi yoroheje, yinjira aturutse mu gice cyo hejuru cy’umunara wo kuyungurura.

Gazi iri hejuru y'umunara wo kuvugurura inyura mu gikoresho gikonjesha gaze ya aside ikagera mu gikoresho gitandukanya gaze ya aside. Gazi iva mu gikoresho gitandukanya gaze ya aside yoherezwa mu buryo bwo gusohora gaze ya aside, hanyuma condensate igashyirwamo umuvuduko na pompe yo kugarura hanyuma ikoherezwa mu gikoresho gitandukanya flash.

Isoko y'ubushyuhe bw'icyuma gihindura ubushyuhe cy'umunara wo kuvugurura ishyushywa n'amavuta yo kohereza ubushyuhe.

Ibikoresho by'ingenzi by'iyi mashini ni umunara wo kwinjizamo umwuka n'umunara wo kuvugurura.

2) Ibipimo by'igishushanyo

Ubushobozi bwo gukoresha: 10×10 ⁴ Nm ³ /umunsi

Gazi yo koza CO₂ igishushanyo mbonera: 3%

Igitutu cy'umunara ukoresha ingufu: 5Mpa.G

Ubushyuhe bw'umunara wo kwinjizamo: 40 ℃ ~ 60 ℃

Umunara wo kuvugurura: 0.03 Mpa.G~0.05 Mpa.G

Ubushyuhe bw'imikorere y'umunara wo kuvugurura: 95 ℃ ~ 120 ℃

Isoko y'ubushyuhe busubira: Gushyushya amavuta yo kohereza ubushyuhe

CO₂ Gazi iri muri gaze yakuwemo karubone ni ≤50ppm
