1 Technology and Innovation on Energy Saving in Chlor-alkali Industry JIANGYIN ANCAN ELECTROCHEMICAL EQUIPMENT LTD. By Mr. Gao Jian

2 Contents Caustic/Chlorine Cost Constituents and Reduction 1 ANCAN Technology Innovation to Stay Ahead of Production 2 ANCAN Technical Support and Service 3 Conclusion 4

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

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

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

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

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

8 Gasket Activated Mesh Elastic Mesh Membrane Anode Mesh Zero Gap Modification of Asahi Kasei Electrolyzer Technology Innovation to Stay Ahead of Production Cost 2

9 Gasket Elastic Mesh Activated Mesh Membrane Anode Mesh Zero Gap Modification of BiTAC Electrolyzer ANCAN Technology Innovation to Stay Ahead of Production 2

10 Zero Gap Modification of F2 Electrolyzer Activated Mesh Elastic Mesh Activated Mesh Elastic Mesh ANCAN Technology Innovation to Stay Ahead of Production 2

11  Technology of Reducing DC by Reducing Voltage Improved Anode Coating Improved Cathode Coating ANCAN Technology Innovation to Stay Ahead of Production 2

12 ANCAN Coating - Anode Membrane Electrolyzer Anode Coating : ◆ Excellent electrochemical characteristics and longer life. ◆ Lower chlorine evolution potential, higher anode efficiency ◆ Good resistant properties against deposit of anolyte contaminants Anode Coating Magnified ANCAN Technology Innovation to Stay Ahead of Production 2

13 Membrane Electrolyzer Cathode Coating ◆ Stable and good electrolysis property and can resist some degree of polarity reversal. ◆ Lower Electric potential ◆ Good resistant properties against deposit of catholyte contaminants ANCAN Coating -Cathode Cathode Coating Magnified ANCAN Technology Innovation to Stay Ahead of Production 2
