Alkali concentration

Our developments have set new standards in the high concentration of alkalis for over 60 years. In this field, Bertrams Chemical Plants Ltd. is the worldwide benchmark.

Plants built by Bertrams Chemical Plants Ltd. concentrate caustic potash and caustic soda in the chlor-alkali industry. Depending on customer requirements, the end product is either a pre-concentrated solution or an anhydrous production in form of: flakes, prills or solidified in drums.

The systems we developed set new standards worldwide in the high concentration of alkalis.

We work in close cooperation with our customers to evaluate all process engineering and economic factors and create a balanced conceptual design. At the quotation stage, we deliver professional advices to our clients, followed by plant detailed design and construction – from evaporation unit up to product filling and handling systems.
