Introduction of High Efficiency Ion Exchange Membrane Electrolyzer in Caustic Soda Production Plant
- Representative Participant
- Asahi Glass Co., Ltd.
Outline of GHG Mitigation Activity
AGC Chemicals (Thailand) Co. Ltd (ACTH) produces caustic soda and chlorine with old ion exchange membrane (IEM) electrolyzers in their Phrapradaeng factory. In this project, the old electrolyzers are replaced by the latest, i.e. the most advanced, IEM electrolyzers with the newest membrane in order to reduce power consumption largely, which leads to the reduction of environmental burden and production cost.
Compared to currently most used IEM electrolyzers, the latest electrolyzers have multiple improvements in electrodes, inner structures and membrane and these improvements contribute to lowering the resistance and power consumption.
Expected GHG Emission Reductions
= Reference emission reductions (RE) – Project emission reductions (PE)
- RE: Amount of electricity consumption of a currently most used IEM electrolyzer is multiplied by the grid emission factor
- PE: Amount of electricity consumption of a latest IEM electrolyzer is multiplied by the grid emission factor
