Outline of GHG Mitigation Activity

JANA produces chlorine and caustic soda, which consumes much electrical power. This project is intended to replace the existing elements of ion exchange membrane (IEM) brine electrolyzers to the latest high efficiency model which will contribute to reducing energy consumption.

The bipolar electrolyzer consists of multiple elements, which have cathode and anode chambers, and IEMs are installed betweeneach element. The high efficiency model is designed to optimize elements’ inner structures and electrode shape, reducing resistance (lowering the voltage) of various components and preventing the mechanical damage for IEM, and thus have achieved lower power consumption.

Expected GHG Emission Reductions

3,289 tCO2-eq./year

Emission reductions are calculated by comparing 2 electrolyzers of different manufactures.
Emission reductions
= Reference emission reductions (RE) – Project emission reductions (PE)
 RE: Specific GHG emissions (non-efficiency model) x amount of chlorine gas produced
 PE: Specific GHG emissions (high efficiency model) x amount of chlorine gas produced
