Soda Potash Plant Chemicals

Product Overview

Soda ash (sodium carbonate, Na₂CO₃) and potash (potassium carbonate, K₂CO₃) manufacturing processes involve complex chemistry including carbonation of brine solutions, crystallisation, evaporation, and calcination. At multiple stages, specialty process chemicals are required to control crystal size, improve liquor clarity, prevent scaling of evaporator and heat exchanger surfaces, suppress foam formation, and achieve efficient solid-liquid separation.

Cleanex Chemicals provides a targeted range of chemicals for soda and potash plant operations: anionic and cationic flocculants for carbonation tower clarifiers and washing filters, scale inhibitors for evaporator systems, high-temperature stable antifoams for evaporator bodies, and filter aids for rotary vacuum and pressure filters. Our products are engineered to function reliably in the high-alkalinity, high-temperature environments typical of soda ash production.
