Kunezindlela ezimbili zezimboni zokukhiqizacaustic soda: Ukuqamba kanye ne-electrolysis. Indlela ye-Causticial ihlukaniswe nge-Soda Ash Causticization Meet kanye ne-Natural Alkali Causticial indlela ngokuya ngezinto zokwakha ezihlukile; Indlela ye-electrolysis ingahlukaniswa ibe yi-diaphragm indlela ye-electrolysis nendlela yokushintshana nge-membrane.
Indlela ye-Soda Ash Causticial indlela: I-Soda Ash kanye ne-Lime baguqulwa babe yisixazululo se-soda ash kanye nomlotha kuguqulwa kube ubisi lwe-lime ngokulandelana. Ukusabela kwe-Casticial ukusabela kwenziwa ngo-99-101 ℃. Uketshezi lwe-causticilization lucacisiwe, luhanjiswa futhi lugxile ku-40%. Uketshezi we-caustic soda. Uketshezi oluhlanganisiwe luhlanganiswe futhi luqinisekiswa ukuthola umkhiqizo oqinile we-caustic soda aqediwe. Udaka olukhathazeke lugezwa ngamanzi, futhi amanzi okugeza asetshenziselwa ukuguqula i-alkali.
Indlela ye-Trona Causticial: Trona ichotshozwa, incibilika (noma i-alkali halogen), yacaciswa, bese ubisi lime lungezwa ku-95 kuye ku-100 ° C. Uketshezi oluqandisiwe lucacisiwe, luhanjiswa, futhi lugxile ekugxilisweni kweNaoh okungama-46%, futhi kufakwe uketshezi olucacile. , ukuhanjiswa kosawoti kanye nokubilisa okwengeziwe ukugxila ukuze uthole umkhiqizo oqinile we-caustic soda aqediwe. Udaka olwenziwe luhlanzwa ngamanzi, futhi amanzi okugeza asetshenziselwa ukuncibilikisa i-TRONA.
I-Diaphragm Indlela ye-electrolysis: engeza i-soda ash, i-caustic soda, kanye ne-barium chloride ukugxilisa ukungcola okufana nosawoti wokuqala onamafutha, bese ufaka i-sodium polyacrylate noma i-bran ekhethiwe kuya ethangini lokucacisa ukuze usheshise kwezulu, futhi I-Sand Filtration ngemuva kwalokho, i-hydrochloric acid ingezwe ukungathathi hlangothi. I-brine iyakashaywa futhi futhi yathunyelwa ku-electrolysis. I-electrolyte isekashaywa kangaka, ihanjiswa, ihlukaniswe ngosawoti, futhi ipholile ukuthola i-liquid caustic soda, okugxilwe kakhulu ukuthola umkhiqizo ophelile we-caustic soda. Udaka ludaka ukugeza amanzi asetshenziselwa ukuncibilikisa usawoti.
I-ION Exchange Membrane indlela: Ngemuva kosawoti wokuqala uguqulwa ube usawoti, i-brine icwengiswa ngokwendlela yendabuko. Ngemuva kokuthi i-brine eyinhloko ihlungiwe ngesihlungi se-microporous se-microborous carbor turur turur turur ukukhiqiza igesi ye-chlorine egumbini lama-anode. I-NA + E-Brine eShenga le-anode ingena eChamber Chamber ngokusebenzisa i-Ion membrane kanye ne-oh- egumbini laseKathode likhiqiza i-sodium hydroxide. H + ukhishwa ngqo eKathode ukukhiqiza igesi ye-hydrogen. Ngesikhathi senqubo ye-elekthrolsis, inani elifanele le-hydrochloric acid eliphakeme lingezwe egumbini lama-anode ukuze lisebenzise ohamb, futhi amanzi ahlanzekile adingekayo kufanele angezwe egumbini laseKathode. I-caustic pureity soda ekhiqizwe egumbini laseKathode linokuhlushwa okungama-30% kuya ku-32% (isisindo), esingahle sisetshenziswe ngokuqondile njengomkhiqizo we-caustic we-caustic sooda.
