Pono e kālailai ʻia ka hoʻohana ʻana o ka evaporative crystallization skid i ka mālama ʻana i ka wai ʻino o ka hale hana hoʻomaʻemaʻe kinoea kūlohelohe me ka hui pū ʻana me ke kiʻikuhi pae o Na2SO4-NaCl-H2O. ʻAʻole wale ka evaporative crystallization ke kaʻina hana o ka hoʻokaʻawale ʻana i ka paʻakai a me ka wai, akā hiki ke hoʻohui pū i nā ʻano solubility o kēlā me kēia paʻakai inorganic e hoʻokaʻawale pono i ka paʻakai inorganic ma ke ʻano pae i loko o ka ʻōnaehana evaporative crystallization. Me ke kākoʻo ʻia e ke kaulike pae, hiki ke hoʻohana ʻia ka ʻenehana ʻaʻole wale nō i ka mālama ʻana i ka wai ʻino o nā hale hana hoʻomaʻemaʻe, akā i ka wai kahua kinoea, ka brine lalo honua, ka wai loko paʻakai a me ka wai ʻino e loaʻa ana nā paʻakai inorganic like ʻole. Ma ke kumu o ka hoʻokaʻawale ʻana i ka wai paʻakai, hiki ke hoʻokō hou ʻia ka hoʻokaʻawale ʻana i ka paʻakai paʻakai. Hiki ke hoʻohana hou ʻia nā paʻakai inorganic i hoʻokaʻawale ʻia e like me ke ʻano o ka hoʻokaʻawale ʻana, a i ʻole e hoʻohana ʻia ma ke ʻano he mea maka kemika, a i ʻole ma ke ʻano he paʻakai mahi holoholona, ʻaʻole hiki ke hoʻomaopopo wale i ka hoʻokuʻu ʻole ʻana o ka wai ʻino terminal, akā e hoʻomaopopo pū i ka hana hou ʻana o nā ʻano kumuwaiwai waiwai like ʻole.
ʻO ka wai ʻōpala mai ka hale hana hoʻomaʻemaʻe e komo mua i ka ʻāpana mālama membrane RO. Ma hope o ka hoʻohuihui ʻana o ka membrane ʻelua pae, hoʻohana hou ʻia ka wai hou. Komo ka wai i hoʻohuihui ʻia i loko o ka loko i hoʻohuihui ʻia a komo i loko o ka ʻōnaehana crystallization evaporative ma o ka pamu hānai. I loko o ka ʻōnaehana crystallization evaporative, ma muli o ka solubility ʻokoʻa o Na2SO4 a me NaCI, me ka hoʻoheheʻe ʻana o ka wai, hoʻohui hou ʻia ka wai mea, a makemake ʻia ʻo Na2SO4 e crystallized a hoʻoheheʻe ʻia e hana i ka slurry nitrate. Komo ka slurry nitrate i loko o ka ʻōnaehana dehydration centrifugal ma o ka pamu slurry. Ma hope o ka hoʻokaʻawale ʻana o ka wai paʻa-wai, hoʻi ka wai momona centrifugal i ka ʻōnaehana crystallization evaporative, a kūʻai ʻia ka paʻakai paʻa ma ke ʻano he paʻakai ʻoihana. Me ka hoʻoheheʻe ʻana, hoʻonui ʻia ka COD i loko o ka wai maka me ka emi ʻana o ka nui o ka wai, kahi e alakaʻi ai i ka hoʻonui ʻana o ka viscosity o ka wai hānai i loko o ka pahu hoʻoheheʻe a hoʻopilikia nui i ka crystallization o ka paʻakai i ke kaʻina hoʻoheheʻe.
ʻO ka mea hānai o ka skid crystallization evaporative he brine mai ka hāmeʻa electrodialysis upstream, a ʻo ka mana hana o ka skid he 300m3/d. ʻO ka manawa hana makahiki he 8000 hola.
Nā lako hana nui: Skid hoʻohui hana, skid compressor, skid mālama hydrocarbon i hui pū ʻia, mea hana a me ka mea hoʻomalu.

Puna wai paʻakai: wai paʻakai i hoʻohuihui ʻia i hana ʻia e ka mālama ʻana i ka electrodialysis, a me ka wai ʻino maʻamau ma hope o ka mālama ʻana i ka biochemical.
