Kugarura gaze ya BOG
BOG y'uruganda rwa LNG mu by'ukuri ituruka ku mwuka ukomoka ku bimera. Gusohora umwuka wa BOG bitewe no kuvurwa nabi ni ugutakaza nyirabyo kandi bizanatera ibibazo byo kurengera ibidukikije.
Muri rusange, uburyo bwo kugarura lisansi bwa BOG buzakoreshwa gusa mu gushyiraho lisansi, kugira ngo BOG ibashe kongera gukoreshwa.
BOG y'uruganda rwa LNG ikomoka ahanini mu gasanduku gakonje karimo amazi, ikigega cyo kubikamo LNG n'ibikoresho bya LNG.
Gukira kwa BOG mu gasanduku k'inkonje
Uburyo BOG itembera mu gasanduku gakonje biterwa n'ubushyuhe bwa LNG iva mu gasanduku gakonje, ingano ya azote muri LNG n'umuvuduko wa flash. Kugira ngo hagenzurwe uburyo BOG itembera mu gasanduku gakonje, ubushyuhe bwa LNG iva mu gasanduku gakonje bugomba kuba buhamye kuri - 163 ℃ mu miterere no mu mikorere; Iyo ingano ya azote mu gasanduku gatanga umusaruro irenze agaciro runaka, hagomba gushyirwaho umunara wo gupima amashanyarazi. BOG yamuritswe mu gikoresho gitandukanya LNG isubira mu gikoresho gihindura ubushyuhe kivamo liquefaction hanyuma ikinjira muri sisitemu ya lisansi nyuma yo kongera gukoresha ubushobozi bwo gukonjesha.
Gusubiza ikigega cy'ububiko bwa LNG
Urujya n'uruza rwa BOG rw'ikigega cyo kubikamo LNG ruterwa kandi n'ubushyuhe bwa LNG, ingano ya azote muri LNG n'umuvuduko w'ikigega cyo kubikamo. Ikigega cyo kubikamo ubushyuhe buke BOG yongera gushyuha hakoreshejwe icyuma gishyushyamo amazi, gishyirwamo umuvuduko na compressor ya BOG hanyuma kikazamurwa.
Kugarura LNG mu isanduku yo gupakira ibikoresho
BOG iri ku mubyimba na yo ifite ubushyuhe buri hasi. Iyo imaze kongera gushyushywa n'icyuma gishyushya cya BOG, ishyirwamo igitutu na compressor ya BOG hanyuma igasubizwamo.
Urujya n'uruza rw'agasanduku gakonje ka BOG n'agasanduku k'ububiko birahamye, mu gihe urujya n'uruza rwa BOG ku mutwaro ruhinduka cyane bitewe n'ingano y'umutwaro, bityo sisitemu ya compressor ya BOG igomba kuba ishobora gusubiza iri hindagurika rikomeye uko igihe kigenda. Dukoresha uburyo bwo kugenzura uburyo umwuka winjira muri compressor (uburyo bwo kugenzura uburyo icyuma gikoresha screw cyangwa uburyo icyuma gikoresha screw). Iyo uburyo umwuka winjiramo bugeze ku rugero ntarengwa, dukoresha valve yo kugarura kugira ngo dufashe uburyo bwo kugenzura, kugira ngo ingufu za BOG zishobore guhinduka neza n'impinduka mu muvuduko munini no kugera ku kugaruka kwa BOG burundu.
Gutemba kw'agasanduku gakonje
Iyo agasanduku gakonje k'uruganda rwa LNG gakora ku bushyuhe buri hasi bwa dogere 163, icyuma gihindura ubushyuhe, valve n'imiyoboro bigomba kugira ingaruka z'ubushyuhe mu gihe cyo gutangira, gukora bisanzwe no gufunga, bishobora gutuma gazi itwika iva mu buryo bitewe n'imiterere cyangwa ikorwa, bigatera impanuka zo gutwika cyangwa guturika. Twafashe ingamba nyinshi zo gukuraho ibyo bibazo:
Igishushanyo mbonera cy'agasanduku gakonje kirimo isesengura ry'imiyoboro kugira ngo hagenzurwe imiyoboro iri mu rugero rwemewe n'aho ituruka.
Nta miyoboro ihuza imiyoboro n'ibigega biri mu gasanduku gakonjesha, kandi byose ni imiyoboro ihujwe.
Valve zose zishyirwa hanze y'agasanduku gakonjesha, ibyo ntibikuraho gusa aho amazi asohoka, ahubwo binafasha kubungabunga valve.
Agasanduku gakonjesha gafite icyuma gipima gazi isharira n'icyuma gipima ubushyuhe kugira ngo gakurikirane ubwinshi bwa gazi n'ubushyuhe mu gasanduku gakonje mu gihe nyacyo.
Kora ubushakashatsi ku gupima amazi ya helium mass spectrometry uko bikenewe.
