Year: 2026
Type: conference-paper
Abstract: This article presents the results of experimental studies on a small-volume rotary-disc mixer in a gas-liquid system, using the interaction between carbon dioxide (CO2) and a sodium carbonate solution as an example. The objective of the study was to evaluate the potential of a rotary-disc reactor for carbonating a soda solution to produce purified sodium bicarbonate. During the experiments, the operating characteristics of the mixer were studied and the efficiency of the soda solution saturation with carbon dioxide was analyzed. The obtained data were compared with the performance of industrial bubble-type devices traditionally used in this field. The study demonstrated that using a small-volume rotary-disc mixer increases carbonation efficiency compared with bubble-type devices and reduces specific energy consumption. Furthermore, the feasibility of using this type of mixer as a carbonizer to purify a soda solution using carbon dioxide from a carbonation column was confirmed. Thus, the results of the study demonstrate the potential for introducing rotary-disc mixers into industrial carbonation processes. Their use can improve energy efficiency of production and optimize technological lines for the production of sodium bicarbonate.
