Rapid Development of Chlor-alkali in China Caustic/Chlorine Cost Constituents and Reduction 1 Rapid Development of Chlor-alkali in China Caustic Capacity Ranked First in the World Since 2006. X10,000 ton NaOH Year

Caustic/Chlorine Production Cost Constituents Caustic/Chlorine Cost Constituents and Reduction 1 Caustic/Chlorine Production Cost Constituents

Method of Reduce DC Power Consumption Caustic/Chlorine Cost Constituents and Reduction 1 Method of Reduce DC Power Consumption Unit Cost of Electricity DC Power Cost = Voltage x x Efficiency x Current Average Current to Decide Production Capacity Improve Membrane Efficiency Reduce Average Electricity Cost Reduce Average Voltage

ANCAN Technology Innovation to Stay Ahead of Production 2 Technology Innovation of Reducing DC Power Consumption Zero Gap Modification Elastic mesh Many existing membrane electrolyzer are finite gap. ANCAN can modify the electrodes to zero gap. Activated mesh

Benefit of Zero Gap Modification --- Comparing with Finite Gap ANCAN Technology Innovation to Stay Ahead of Production 2 Technology Improvement on Reducing DC Power Benefit of Zero Gap Modification --- Comparing with Finite Gap 1 Lower cell voltage --- Saving of > 140 kWh/t 100% NaOH 2 Can increase operating current, equivalent to >10% of production increase 3 Reduce membrane vibration, prolong membrane life span 4 More even current distribution, safer operating condition Requirement ---Zero Gap Modification ---Cell Voltage Monitoring ---Differential Pressure Control and Protection ---Operation Skill
