Enwere ụzọ abụọ maka mmepụta ihentụ ọka soda: causticization na electrolysis. A na-ekewa usoro causticization na soda ash causticization usoro na usoro causticization alkali dị ka ihe dị iche iche si dị; Enwere ike kewaa usoro electrolysis ka ụzọ diaphragm electrolysis na usoro akpụkpọ ahụ mgbanwe ion.
Usoro ntụ ntụ ntụ ntụ: Soda ntụ na wayo na-atụgharị ka ọ bụrụ ntụ ntụ soda na ntụ na-atụgharị ka ọ bụrụ mmiri ara ehi wayo n'otu n'otu. A na-eme mmeghachi omume causticization na 99-101 ℃. A na-akọwapụta mmiri mmiri causticization, kpochapu ma tinye uche karịa 40%. Mmiri caustic soda. A na-etinyekwu uche na mmiri a gbadoro anya ma sie ike iji nweta ngwaahịa caustic soda siri ike. A na-eji mmiri na-asacha apịtị na-eme ka ọ dị nro, a na-ejikwa mmiri ịsa ahụ gbanwee alkali.
Usoro causticization nke Trona: a na-egwepịa trona, gbazee (ma ọ bụ alkali halogen), dokwuo anya, wee tinye mmiri ara ehi lime ka ọ bụrụ 95 ruo 100 ° C. A na-eme ka mmiri mmiri a na-eme ka ọ pụta ìhè, kpochapu, ma tinye ya na ntinye NaOH nke ihe dịka 46%, na mmiri mmiri doro anya na-ajụkwa oyi. , nnu ọdịda na n'ihu esi ka itinye uche iji nweta siri ike caustic soda okokụre ngwaahịa. A na-eji mmiri na-asacha apịtị a na-eme ka ọ dị mma, a na-ejikwa mmiri ịsa ahụ gbazee trona.
Usoro electrolysis nke diaphragm: tinye soda ash, caustic soda, na barium chloride uche iji wepụ adịghị ọcha dị ka calcium, magnesium na sulfate ion mgbe nnu salinized mbụ, wee tinye sodium polyacrylate ma ọ bụ causticized bran na tank nkọwa iji mee ka mmiri ozuzo dịkwuo elu, na ájá filtration E mesịa, a na-agbakwunye hydrochloric acid maka nkwụsịtụ. A na-ebucha brine ahụ ọkụ ma zigara ya na electrolysis. A na-ekpocha ọkụ electrolyte ahụ, kpochapu ya, kewaa ya n'ime nnu, ma mee ka ọ dị jụụ iji nweta soda mmiri mmiri, bụ nke a na-etinyekwu uche iji nweta ngwaahịa a rụchara nke soda caustic siri ike. A na-eji mmiri ịsa ụrọ nnu na-agbaze nnu.
Usoro akpụkpọ ahụ nke ion mgbanwe: Mgbe nnu mbụ gbanwere ghọọ nnu, a na-anụcha brine dịka usoro omenala siri dị. Mgbe emechara brine bụ isi site na nzacha microporous sintered carbon tubular filter, a na-anụcha ya ọzọ site na ụlọ elu resin resin chelating iji mee Mgbe ọdịnaya calcium na magnesium dị na brine dara n'okpuru 0. 002%, brine a nụchara anụcha nke abụọ bụ electrolyzed. iji mepụta gas chlorine n'ime ụlọ anode. Na + dị na brine na ụlọ anode na-abanye n'ime ụlọ cathode site na akpụkpọ ahụ ion na OH- na ụlọ cathode na-emepụta sodium hydroxide. A na-ahapụ H + ozugbo na cathode iji mepụta hydrogen gas. N'oge usoro electrolysis, a na-agbakwunye acid hydrochloric dị elu kwesịrị ekwesị n'ime ụlọ anode iji wepụ OH- remigated, na mmiri dị ọcha achọrọ kwesịrị ịgbakwunye na ụlọ cathode. Soda caustic dị elu nke na-eme na ụlọ cathode nwere ntinye nke 30% ruo 32% (mass), nke a pụrụ iji ya mee ihe ozugbo dị ka ngwaahịa alkali mmiri, ma ọ bụ nwee ike itinyekwu uche na-emepụta ngwaahịa soda siri ike.
