Tekinoroji yingenzi yo Kugarura gaze ya BOG na Cold box yamenetse

Kugarura gaze ya BOG

BOG y'uruganda rwa LNG mubyukuri biva muri gaze yo kugaburira. Guhindura BOG biterwa no kuvurwa bidakwiye nigihombo cya nyiracyo kandi bizanatera ibibazo byo kurengera ibidukikije.

Muri rusange, kugarura BOG bizakoreshwa rwose mugushiraho gaze ya lisansi, kugirango BOG isubirwemo.

BOG y'uruganda rwa LNG ituruka cyane cyane mu gasanduku gakonje gakonje, ikigega cya LNG hamwe no gupakira LNG.

Agasanduku gakonje BOG gukira

Imigezi ya BOG yisanduku ikonje biterwa nubushyuhe bwa LNG mu gasanduku gakonje, ibirimo azote muri LNG hamwe nigitutu cya flash. Kugirango ugenzure imigendekere ya BOG mu gasanduku gakonje, ubushyuhe bwa LNG buva mu gasanduku gakonje bugomba kuba buhagaze kuri - 163 design mugushushanya no gukora; Nyuma ya azote iri muri gaze yo kugaburira irenze agaciro runaka, hazashyirwaho umunara wa denitrification. BOG yamuritse muri LNG itandukanya isubira mumazi yubushyuhe kandi yinjira muri gaze ya lisansi nyuma yo kugarura ubushobozi bwo gukonjesha.

Ububiko bwa LNG bog kugarura

Imigezi ya BOG yububiko bwa LNG nayo iterwa nubushyuhe bwa LNG, ibirimo azote muri LNG hamwe nigitutu cyo kubika. Ikigega cyo kubika ubushyuhe buke BOG gishyuha nubushyuhe bwa bog, kotswa igitutu na compressor ya BOG igakira.

LNG yikuramo bog kugarura

BOG ku gupakira nayo ni ubushyuhe buke. Nyuma yo gushyukwa nubushyuhe bwa BOG, byotswa igitutu na compressor ya BOG hanyuma igakira.

Urujya n'uruza rw'isanduku ikonje BOG hamwe na tank yo kubika bog irahagaze neza, mugihe urujya n'uruza rwa BOG kumuzigo uhinduka cyane hamwe nubunini bwo gupakira, bityo sisitemu ya compressor ya BOG igomba kuba ishobora gusubiza iyi ihindagurika rinini mugihe. Twifashishije amabwiriza yo gufata ikirere cya compressor (slide valve igenga imashini ya screw cyangwa kugenzura ikirere cyo gufata imashini isubiza). Iyo amabwiriza yo gufata ikirere ageze kuri byinshi, dukoresha valve yo kugaruka kugirango dufashe amabwiriza, kugirango igitutu cya BOG gishobora guhuza byimazeyo nimpinduka nini nini kandi bigere ku gukira kwuzuye kwa BOG.

Agasanduku gakonje

Iyo agasanduku gakonje k'uruganda rwa LNG gakorera ku bushyuhe buke bwa - 163 ℃, guhinduranya ubushyuhe, valve n'umuyoboro bigomba guhura n'ingaruka ziterwa n'ubushyuhe mugihe cyo gutangira, gukora bisanzwe no guhagarika, ibyo bikaba bishobora gutuma imyuka yaka. muri sisitemu kubera igishushanyo cyangwa impamvu zo gukora, bikaviramo gutwikwa cyangwa impanuka ziturika. Twafashe ingamba nyinshi zo gukuraho ibibazo nkibi:

Igishushanyo gikonje gikubiyemo isesengura ryimihindagurikire yimiyoboro kugirango igenzure impagarara mu miyoboro yemewe kuva isoko.

Ntaho bihurira hagati yimiyoboro nimiyoboro mumasanduku ikonje, kandi byose birahujwe.

Imyanda yose yashyizwe hanze yisanduku ikonje, ntabwo ikuraho gusa aho yamenetse, ahubwo inorohereza kubungabunga valve.

Agasanduku gakonje gafite ibyuma byaka umuriro hamwe nubushyuhe bwo kugenzura ubushyuhe bwa gaze hamwe nubushyuhe mu gasanduku gakonje mugihe nyacyo.

Kora helium mass spectrometry yamenetse nkuko bisabwa.
