Continuous Production of High-Purity NaHCO3 via Carbonation of NaOH: Thermodynamic Analysis and Two-Stage Reactor Design

Abstract This study established a high-purity continuous production system for NaHCO3 via NaOH carbonation. Using simulated flue gas containing CO2 and NaOH solutions, the reaction mechanism was elucidated through real-time monitoring of pH and electrical conductivity, revealing...
