Nā mea kūʻai kiʻekiʻe o Kina LNG Gas Plant - 1 ~ 5 × 104NM3 / D MINI LNG LIQUEFACTION - Rongteng

Pono

(1) palekana a hilinaʻi

He 230 ℃ kiʻekiʻe ke kiʻekiʻe o ka LNG ma mua o ka ʻaila a ʻoi aku ka kiʻekiʻe ma mua o ka diesel; ʻO ka palena pahū o LNG he 2.5 ~ 4.7 manawa kiʻekiʻe ma mua o ka ʻaila; ʻO ka mānoanoa pili o LNG ma kahi o 0.43 a ʻo ka ʻaila ma kahi o 0.7. ʻOi aku ka māmā ma mua o ka ea. ʻOiai inā he liʻiliʻi liʻiliʻi, e hoʻoheheʻe ʻia a hoʻopuehu koke, i ʻole e hoʻopau koke ʻia a pahū a i ʻole ka palena o ka pahū ʻana i ke ahi. No laila, he ikehu palekana ka LNG.

(2) hoʻomaʻemaʻe a me ka hoʻomalu kaiapuni

Wahi a ka sampling analysis a me ka hoʻohālikelike ʻana, ʻo LNG, ma ke ʻano he wahie kaʻa, hoʻemi i ka hoʻokuʻu piha ʻana ma kahi o 85% i hoʻohālikelike ʻia me ka ʻaila a me ka diesel, me 97% ka emi ʻana o ka hoʻokuʻu ʻana o CO, 70% ~ 80% ka hoʻēmi ʻana i ka HC, 30% ~ 40% ka emi ʻana o NOx, 90% ka hoʻemi ʻana i ka CO2, 40% no ka hoʻemi ʻana i ka hoʻokuʻu ʻana i ka CO2, 40%. Eia kekahi, ʻaʻohe carcinogens e like me ke kēpau a me ka benzene, ʻaʻohe kumu o ka sulfide, a he hana hoʻomalu maikaʻi loa. No laila, he ikehu maʻemaʻe ka LNG.

(3) waiwai a maikaʻi

Ma hope o ka liquefaction, hoʻemi ʻia ka nui o ka LNG ma kahi o 1 / 625 o kēlā o ke kinoea kūlohelohe, a ʻo kāna kumukūʻai mālama he 1 / 70 ~ 1/6 wale nō o ke kinoea kūlohelohe. Loaʻa iā ia nā pōmaikaʻi o ka haʻahaʻa haʻahaʻa, ka liʻiliʻi o ka noho ʻana a me ka maikaʻi o ka mālama ʻana. Eia hou, hiki ke hana hou ʻia ka mana hoʻoluʻu i lawe ʻia e LNG.

(4) maʻalahi a maʻalahi

Hiki i ka LNG ke lawe i ka nui o ke kinoea maoli i kekahi mea hoʻohana i paʻakikī ke hele ma o ka pipeline ma o kahi kaʻa pahu kūikawā a moku paha, ʻaʻole ia e mālama wale i ka hoʻopukapuka e hoʻohālikelike ʻia me ka pipeline hoʻoili kinoea lalo, akā he mea maʻalahi hoʻi, hilinaʻi, haʻahaʻa haʻahaʻa a me ka hoʻololi ikaika. Wahi a nā helu helu, ʻoi aku ma mua o 100 LNG peak shaving device i kūkulu ʻia a hoʻohana ʻia ma ʻAmelika Hui Pū ʻIa, Iapana a me ʻEulopa. ʻAʻole ia e hoʻopakele wale i ka ʻāina, ke kapikala a me ka manawa kūkulu i hoʻohālikelike ʻia me ke kūkulu ʻana i nā pahu mālama kinoea kiʻekiʻe kiʻekiʻe a me ka mālama kinoea ma lalo o ka honua, akā maʻalahi hoʻi, maʻalahi a ʻaʻole i kaupalena ʻia e nā kūlana geological. No nā ʻāina me ka lawa ʻole o nā kumu kinoea, ʻo ka lawe ʻana mai i ka LNG ke ala maʻalahi a me ka hoʻokele waiwai e hoʻoponopono i kā lākou lako kinoea. Eia hou, hiki ke hoʻohuehu maʻalahi ka LNG me ka wai kai.
