Nā mea kūʻai aku kiʻekiʻe o Kina MDEA Decarburization Skid - Evaporation crystallization skid - Rongteng

wehewehe

Pono e nānā ʻia ka hoʻohana ʻana i ka skid crystallization evaporative i ka mālama ʻana i ka wai ʻino o ka mea kanu hoʻomaʻemaʻe kinoea maoli i hui pū ʻia me ke kiʻikuhi o Na2SO4-NaCl-H2O. ʻO ka crystallization evaporative ʻaʻole wale ke kaʻina o ka hoʻokaʻawale ʻana i ka paʻakai a me ka wai, akā hiki ke hoʻohui pū i nā hiʻohiʻona solubility o kēlā me kēia paʻakai inorganic e hoʻokaʻawale i ka paʻakai inorganic ma ka pae i ka ʻōnaehana crystallization evaporative. Kākoʻo ʻia e ka pae equilibrium, hiki ke hoʻohana ʻia ka ʻenehana ʻaʻole wale i ka mālama ʻana i ka wai ʻino o nā mea kanu hoʻomaʻemaʻe, akā pū kekahi i ka wai kīhāpai, underground brine, wai loko paʻakai a me nā wai ʻino i loaʻa nā paʻakai inorganic like ʻole. Ma ke kumu o ka hoʻokaʻawale ʻana i ka wai paʻakai, hiki ke hoʻokō hou ʻia ka hoʻokaʻawale ʻana o ka paʻakai. Hiki ke hoʻohana hou ʻia nā paʻakai inorganic i hoʻokaʻawale ʻia e like me ka maikaʻi o ka hoʻokaʻawale ʻana, a i ʻole hoʻohana ʻia e like me nā mea waiwai, a i ʻole e like me ka paʻakai holoholona, ​​​​ʻaʻole hiki ke ʻike wale i ka hoʻokuʻu ʻole ʻana o ka wai ʻino, akā ʻike pū kekahi i ka hana hou ʻana o nā ʻano waiwai waiwai.

ʻO ka wai ʻino mai ka mea kanu hoʻomaʻemaʻe e komo mua i ka ʻāpana lapaʻau membrane RO. Ma hope o ʻelua mau ʻāpana membrane, hoʻohana hou ʻia ka wai hou. Hoʻokomo ka wai i hoʻopaʻa ʻia i loko o ka ʻauʻau paʻa a komo i ka ʻōnaehana crystallization evaporative ma o ka pā hānai. I loko o ka evaporative crystallization nenoaiu, ma muli o ka likeʻole solubility o Na2SO4 a me NaCI, me ka evaporation o ka wai, ka mea wai mea i hoʻopaʻa 'ia, a Na2SO4 preferentially crystallized a precipitated e hana i ka nitrate slurry. Komo ka slurry nitrate i ka ʻōnaehana dehydration centrifugal ma o ka slurry pump. Ma hope o ka hoʻokaʻawale ʻana i ka wai paʻa, hoʻi ka ʻona makuahine centrifugal i ka ʻōnaehana crystallization evaporative, a kūʻai ʻia ka paʻakai paʻa e like me ka paʻakai ʻoihana. Me ka hoʻoheheʻe ʻana, hoʻonui ʻia ka COD i loko o ka wai maka me ka emi ʻana o ka ʻike wai, e alakaʻi ana i ka hoʻonui ʻana o ka viscosity o ka wai hānai i loko o ka pahu evaporation a hoʻopilikia koʻikoʻi i ka crystallization o ka paʻakai i ke kaʻina evaporation.

ʻO ka meaʻai meaʻai o ka skid crystallization evaporative he brine mai ka mea hana electrodialysis upstream, a ʻo ka hiki ke hana o ka skid he 300m3/d. ʻO ka manawa hana makahiki he 8000 hola.
ʻO nā mea hana nui: ʻO ka skid hoʻohui kaʻina hana, ka skid compressor, ka skid storage hydrocarbon hui ʻia, ka mea kani a me ka mea hoʻokele.

Nā kūlana brine
