Carbonation reaction crystallization is a gas-liquid reaction crystallization process for the formation of salts by the reaction of CO2 with alkali,
The absorption rate of carbon dioxide and crystal particle size are important indexes for the design of carbonation reaction crystallizer.
The design of the carbonation reaction crystallizer has a larger heat exchange area to remove the reaction heat in time,
carbonization process is usually carried out under high pressure to promote the direction of reaction.
The device improves the utilization ratio of CO2 by increasing the contact time of gas - liquid and the effective distribution of gas.
Control measures for affecting crystal size distribution and particle size: Flow field environment of crystallizer, with or without agitating device, and the type of agitating.
There are various forms of carbonation reaction crystallizer, and the directional design is carried out according to the different process and product requirements, which can meet the customer requirements well.
Crystallization of CO2 and alkali solution during the production of carbonate, such as potassium carbonate, sodium carbonate and calcium carbonate.
