Kiʻekiʻe ʻO China LNG Plant Skid Factory - Hana ʻia 50 × 104m3 / D mea kanu liquefaction kinoea maoli - Rongteng

Hoʻolauna

ʻO ke kūkulu ʻana o ka papahana 50 × 10⁴m³/ D papahana hoʻoheheʻe kinoea maoli a me nā mea kākoʻo a me hoʻokahi pahu pahu piha 10000 m3 LNG. ʻO nā ʻāpana kaʻina hana nui e pili ana i ka hoʻoulu ʻana i ke kinoea feed, ka decarbonization unit, dehydration unit, mercury a me ke kaumaha hydrocarbon removal unit, liquefaction unit, refrigerant storage, flash steam pressurization, LNG tank farm a me nā lako hoʻouka.

Pehea e hana ai ka lapaʻau pre-liquefaction o ke kinoea maoli?

Hele mai ka punawai o ka ai mea kanu ma ke ano kinoea ma ka paipu. Loaʻa i ke kinoea maoli i unuhi ʻia mai ka lepo mai nā haumia, ka wai a me nā wai e pili ana, no laila ma mua o ka hiki ʻana o ka liquefaction, pono ke kinoea e hele i kahi kaʻina hana e wehe ai i nā mea makemake ʻole. Hele ke kinoea i loko o nā moku, compressors a me nā paipu kahi e hoʻokaʻawale ʻia ai ke kinoea mai nā wai kaumaha a me nā haumia.

ʻO ka mua, hoʻoneʻe ʻia ka wai a me ka condensate, ma hope oka wehe ʻana i ke kinoea ʻakika(carbon dioxide, CO2), hydrogen sulfide (H2S) a me ka mercury (Hg). ʻAʻole makemake ʻia kēia mau mea, no ka mea hiki ke hana i ka hau i ka wā liquefaction a me ka corrosion i nā pipeline a me nā mea hoʻololi wela LNG. Hoʻomaʻamaʻa mua ʻia ke koena hui ʻana, a laila hoʻokaʻawale ʻia nā wai kinoea ʻoi aku ke kaumaha mai ka hui ʻana ma mua o ka liquefaction. Hiki ke mālama ʻia a kūʻai paʻa ʻia nā hydrocarbons i wehe ʻia. ʻO ke kinoea i koe ka hapa nui o ka methane a me kekahi ethane, i lawe ʻia i ka liquefaction.

Pehea ka hana liquefaction o LNG?

ʻO ka lawe ʻana i ke kinoea i hoʻopaʻa ʻia i kahi lōʻihi ma o ka paipu hiki ke lilo i kumu kūʻai a hoʻopau i ka manawa, akā ma ka hoʻoluʻu ʻana i ke kinoea kūlohelohe i -162 ° C, lilo ia i mea wai, a emi kona leo ma 600 manawa. ʻO kēia ka mea hiki ke lawe i ke kinoea ma ka moku, a hiki ke hana ʻia kēia hana ma ka hale kanu LNG. Hoʻokumu ʻia ke kaʻina hoʻoheheʻe ʻana a me ka LNG ma luna o nā pōʻaiapuni thermodynamic refrigeration, a lawe ʻia i loko o nā mea hoʻololi wela cryogenic, kahi e hoʻomoʻa ai i ka wela mai ke kinoea maoli. Hiki ke hoʻohana ʻia ke kinoea uila a me BOG i wahie no nā turbines i hoʻohana ʻia no ka hana mana ma ka pūnaewele.

Hoʻokaʻawale mākou ma waena o ʻelua ʻano nui o nā kaʻina liquefaction: ʻo ke kaʻina cascade maʻamau kahi e hoʻohana ʻia ai nā mea hoʻoheheʻe ʻokoʻa e hoʻoheheʻe ʻia i nā mahana like ʻole, a me ka pōʻai refrigerant hui ʻia kahi e hoʻomaloʻo ai ka hui pū ʻana o nā mea hoʻoheheʻe hoʻokahi. ʻO kēlā me kēia ʻaoʻao, ʻo ka LNG ka hopena, i mālama ʻia i loko o nā pahu cryogenic ma ka pūnaewele ma mua o ka hoʻouna ʻia ʻana.
