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

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

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

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

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

  6. 2 ANCAN Technology Innovation to Stay Ahead of Production 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

  7. 2 ANCAN Technology Innovation to Stay Ahead of Production 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 • 2Can 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

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

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

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

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

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

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

  14. 3 ANCAN Technical Support and Service ◇Full Range of Electrolyzer Maintenance and Repair Service ◇Electrolyzer Components Replacement

  15. INEOS BM-2.7 Asahi Kasei 3 ANCAN Technical Support and Service (Maintenance) Eltech BiTAC DD350 F2 B1 FM-21 SP

  16. 3 ANCAN Technical Support and Service ( spareparts) Other Electrolyzer’s Components PFAFlexible Hose Membrane Electrolyzer Gasket

  17. 3 ANCAN Technical Support and Service (Maintenance) ANCAN has provided technical service and support to more than 130 Chlor-alkali Plants in China. ANCAN’s Partial Reference List outside of China
