Uburyo bwo gusukura gaze karemano bwa 100MMSCFD bufite uburyo bwa MDEA bwo kuyisubiza

Sichuan Hengzhong Clean Energy Equipment Co., Ltd., yavutse mu 2012 kandi dushobora gutanga ibisubizo n'ibikoresho byo gukoresha mu gutunganya imashini zisukura umutwe w'inka, ibikoresho byo kongerera ikirere gazi karemano, ipaki yo kugarura sulfure, Imashini ikuramo LPG n'iy'ubutabazi bwa NGL, Uruganda rukora amazi ya LNG, igikoresho cyo gukora hydrogen, ipaki yo gukuramo heliyumu, amaseti ashyiraho amashanyarazi ya gaze.

Uburyo bwo gusukura umwuka bugizwe n'uburyo butatu: uburyo bwo gutunganya ibyuma, uburyo bwo kugenzura ibyuma n'uburyo bw'imikorere. Dukurikije amasoko atandukanye y'umwuka, bushobora guhindurwa.

Dukurikije uko lisansi iboneka, dukoresha uburyo bwiza kandi buhendutse cyane kugira ngo duhuze n'ibyo abakiriya bakeneye. Ibikoresho bishyirwa ku rubura bituma gutwara no gushyiramo ibintu byoroshye.

1. Uburyo bw'ingenzi bwo gukoresha umuti wa MDEA ukuramo CO2 na H2S:

Imyuka karemano ituruka mu mazi yinjira mu gice cyo gukuraho aside, gikoresha umuti wa MDEA kugira ngo gikuremo imyuka ikomoka kuri aside nka CO2\H2S muri iyo myuka mbisi.

Gazi karemano yinjira mu cyuma gifata umwuka uturutse hasi hanyuma ugatemba hejuru. Umuti wa MDEA wasubiwemo burundu (umuti woroshye) winjira mu cyuma gifata umwuka uturutse hejuru hanyuma ugatemba hasi. Imiyoboro ihuza umuti wa MDEA na gaze karemano bikora ku cyuma gifata umwuka, bikanyunyuza CO2 na H2S muri gaze hanyuma bikayishyira mu gice cy'amazi. Ibice bitarafata umwuka bikurwa hejuru y'icyuma gifata umwuka hanyuma bikinjira mu cyuma gikonjesha gaze kandi gitandukanya umwuka. Gazi isohoka mu cyuma gitandukanya umwuka usohoka yinjira mu cyuma gitanga umwuka mbere yo gukonjesha, hanyuma umwuka wongera umwotsi woherezwa mu cyuma gitanga umwuka.

TIkigereranyo cya CO2 muri gaze karemano yavuwe kiri munsi ya 50 PPM, naho ikigereranyo cya H2S kiri munsi ya 4 PPM.

Umuti wa MDEA wafashe CO2 na H2S, witwa amazi akungahaye, woherezwa kuri flash tower, aho umuvuduko ugabanuka hanyuma gaze karemano isohoka ikoherezwa muri sisitemu yo guhumeka. Amazi akungahaye ahita ahinduranya ubushyuhe n'umuti (amazi akungahaye) uva mu gice cyo hasi cy'umunara wo kuvugurura. Ubushyuhe buzamurwa kugeza kuri ~ 203 °F hanyuma bwoherezwa mu gice cyo hejuru cy'umunara wo kuvugurura, aho ucibwa no kuvugurura kugeza igihe amazi akungahaye agereye ku rugero rw'icyo ushaka.

Amazi yoroheje ava mu munara wo kuvugurura anyura mu cyuma gihindura ubushyuhe bw’amazi yoroheje n’icyuma gikonjesha amazi yoroheje, akonjeshwa kugeza kuri 113 °F, kandi agashyirwamo igitutu n’ipompo y’amazi yoroheje mbere yo kwinjira mu gice cyo hejuru cy’umunara wo kubyutsa.

Gazi isohoka iva hejuru y'umunara wo kuvugurura inyura mu gikoresho gikonjesha gaze ya aside ikagera mu gikoresho gitandukanya gaze ya aside. Gazi isohoka mu gikoresho gitandukanya gaze ya aside yoherezwa muri sisitemu yo gusohora gaze ya aside, hanyuma condensate igasubira mu kigega cya MDEA.

Isoko y'ubushyuhe bw'icyuma gishyushya umunara gishyushya hakoreshejwe amavuta ashyushye.

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

Ibipimo by'igishushanyo:

Ubushobozi bwo gutunganya: 100MMSCFD

Igishushanyo mbonera cy'ingano ya CO2 muri gaze mbisi: 5% (mol %)

Ingano ya H2S mu mwuka mubi ni 8ppmv

Umuvuduko w'umunara ukoresha: 986.1psig

Ubushyuhe bw'imikorere y'umunara ukoresha: 104 ℉ ~ 140 ℉

Umuvuduko w'imikorere y'umunara wo kuvugurura: 4.351psig ~ 7.252psig

Ubushyuhe bw'imikorere y'umunara wo kuvugurura: 203 ℉ ~ 257 ℉

Isoko y'ubushyuhe busubira: Gushyushya amavuta ashyushye

Ingano ya CO2 muri gaze yakuweho aside ≤50PPM

ingano ya gazi mu mwuka wakuweho aside ≤4PPM

3) Ingano y'ikoreshwa

50% ~ 110%

2. Sisitemu yo kugenzura ibyuma

Kugira ngo habeho gukurikirana neza inzira yo gukora ibikoresho byose, no kwemeza ko bikora neza kandi ko byoroshye kubikoresha no kubibungabunga, sisitemu yo kugenzura ibikoresho ikubiyemo ahanini:

Sisitemu yo kugenzura ikwirakwizwa (DCS)

Sisitemu y'ibikoresho by'umutekano (SIS)

Sisitemu yo Gupima Iby'Inkongi y'Umuriro n'Ibyuka Bidakora (FGS)

Televiziyo ifunganye (CCTV)

Sisitemu yo gusesengura

3. Sisitemu y'ibikorwa remezo

Ubu buryo bugizwe ahanini n'ibi bikurikira: igikoresho cy'umwuka, icyuma cya azote, icyuma gitwara amavuta ashyushye, icyuma cy'amazi yakuwemo umunyu n'icyuma gikonjesha amazi azenguruka.
