Te whakaora i te hau BOG
Ko te BOG o te tipu LNG i ahu mai i te hau whāngai. Ko te putanga o te BOG i puta mai i te korenga o te maimoatanga he mate tika mō te rangatira, ā, ka arahi hoki ki ngā raruraru tiaki taiao.
I te nuinga o te wā, ka whakamahia katoatia te whakaora BOG mō te tāutanga o te wahie hau, kia taea ai te hangarua i te BOG.
Ko te nuinga o te pūngao wai o te tipu LNG e ahu mai ana i te pouaka makariri wai, te tāke rokiroki LNG me te uta LNG.
Te whakaora i te pouaka matao o te BOG
Ko te rere o te BOG o te pouaka makariri ka whakawhirinaki ki te pāmahana o te LNG i waho o te pouaka makariri, te ihirangi hauota i roto i te LNG me te pēhanga mura. Hei whakahaere i te rere o te BOG i roto i te pouaka makariri, me pumau te pāmahana o te LNG i waho o te pouaka makariri ki te – 163 ℃ i roto i te hoahoa me te whakahaere; Kia teitei ake te ihirangi hauota i roto i te hau whāngai i tētahi uara, me whirihora he pourewa denitrification. Ko te BOG i mura i roto i te wehewehe LNG ka hoki ki te whakawhiti wera wai, ka tomo ki te pūnaha hau wahie i muri i te whakahokinga mai o te kaha whakamatao.
Te whakaora i te repo o te tāke rokiroki LNG
Ko te rere o te BOG o te tāke rokiroki LNG e whakawhirinaki ana hoki ki te pāmahana LNG, te nui o te hauota i roto i te LNG me te pēhanga o te tāke rokiroki. Ka whakamahanatia anō te tāke rokiroki pāmahana-iti BOG e te whakamahana poka, ka pēhia e te pūwhakakoi BOG, ā, ka whakahokia mai.
Te whakaora i te repo utaina LNG
He iti hoki te pāmahana o te BOG i runga i te uta. I muri i te whakamahana anō e te whakamahana BOG, ka pēhia e te pūwhakakoi BOG, kātahi ka whakahokia mai.
He āhua pumau te rere o te BOG pouaka matao me te repo tāke rokiroki, engari he nui te rerekētanga o te rere o te BOG i runga i te uta me te rahinga uta, nō reira me taea e te pūnaha kōpeke BOG te urupare ki tēnei pikinga nui i roto i te wā. Ka whakamahia e mātou te whakahaere hau e tomo ana i te kōpeke (te whakahaere takirere reti o te mīhini tīwiri, te whakahaere takirere hau e tomo ana i te mīhini tauutuutu rānei). Ina tae te whakahaere hau e tomo ana ki te mōrahi, ka whakamahia e mātou te takirere whakahoki hei āwhina i te whakahaere, kia taea ai e te pēhanga BOG te urutau katoa ki te huringa rere nui me te whakatutuki i te whakaoranga katoa o te BOG.
Te turuturu o te pouaka makariri
Ina mahi te pouaka matao o te tipu LNG i te pāmahana iti o te – 163 ℃, me pāngia tōna whakawhiti wera, tōna takirere me te paipa e te pānga o te ahotea pāmahana i te wā tīmatanga, te mahi noa me te whakaweto, ka arahi pea tēnei ki te turuturu o te hau mura ki roto i te pūnaha nā te hoahoa, te hanga rānei, ka hua ake he aituā mura, he pahū rānei. He maha ngā mahi kua mahia e mātou hei whakakore i ēnei raruraru:
Kei roto i te hoahoa pouaka matao te tātaritanga ahotea o ngā paipa hei whakahaere i te ahotea o ngā paipa i roto i te awhe e whakaaetia ana mai i te pūtake.
Kāore he hononga flange i waenga i ngā paipa me ngā oko i roto i te pouaka makariri, ā, he hononga whakarewa katoa.
Kei waho o te pouaka makariri ngā takirere katoa, e kore e whakakore noa i te pūwāhi turuturu, engari e whakangāwari ana hoki i te tiaki takirere.
Kei roto i te pouaka matao he ine hau mura me te ine pāmahana hei aroturuki i te kukū me te pāmahana o te hau i roto i te pouaka matao i te wā tūturu.
Whakahaerehia te kimi turuturu mō te inenga papatipu helium ina hiahiatia.
