9:50 to 10:10 – Characteristics of FLEMION: Process of Electrolysis, Mr. Nishio, Asahi Glass
Many kinds of ions and water pass through the membrane under electrolysis, and membrane performance depends on the behaviors of these ions. This presentation explains the mechanism of material transport based on the “ion channel model” and shows how the FLEMION channel is applied.
10:10 to 10:40 – Coffee break
10:40 to 11:10 – Characteristics of FLEMION: Ensuring Quality and Purity, Mr. Kaneko, Asahi Glass
This presentation explains the importance of quality of NaOH, Cl,ClO3, SO4 catholyte in ensuring membrane quality and purity.
11:10 to 11:30 – Characteristics of FLEMION: Potential Risks and Recommendations, Mr. Toyoshima, Asahi Glass
This presentation will discuss changes in membrane dimension, causes of blistering, wrinkles, cracks, and the importance of pre-treatment.
11:30 to 11:50 – F-8080 Case Study, John Pawelczyk, Olin
12:00 to 1:15 – Lunch Buffet
1:20 to 1:45 – Electrolytic Technologies for Low Power Consumption, Dermot Gosser, tkUCE
This presentation will discuss tkUCE’s latest technology for ion-exchange chlorine production
1:45 to 2:10 – Protection of Membranes by High-Speed Measurement and Automated Analysis of Single-Cell Voltages, Helmut Lademann, R2
It’s possible to achieve longer membrane and electrode lifecycle if the cells and cell room environment operate in the correct conditions. The EMOS system provides reliable and precise analysis of single cell voltages in real time, taking operating conditions into account. This presentation will discuss how to use the system to prevent performance loss from events like brine impurities and insufficient polarization conditions.
2:10 to 2:30 – Membrane Electrolysis and its Effect on Membrane Electrode Coating, Alan Sherman, De Nora
It is well established that Anode coatings wear as a function of the Tons Cl2 produced per m2 of Anode surface. Recoating costs are predictable, while Anode repair costs are not. This presentation will discuss some techniques to mitigate Anode damages and predict their occurrence.
2:30 to 3:00 – Coffee Break
3:00 to 3:20 – Enhanced Bichlor, Jim Sims, Inovyn
This presentation discusses Inovyn’s Enhanced BiChlor electrolyzer for lower energy consumption, higher operating pressure envelope, and increased production capacity. Asahi Glass membranes have shown to perform well in the BiChlor electrolyzer.
3:20 to 3:40 – High-Performance Elastomers and Plastics for the Electrochemical Industry, Tom Hanshar, Prince Rubber and Plastics
This presentation will discuss how the use of high-performance elastomers and plastics in a cell room can help achieve the maximum life of membranes.
3:40 to 3:55 – Operation and Performance of FLEMION, Mr. Toyoshima, Asahi Glass
To achieve excellent membrane performance and longevity, is important to follow the membrane supplier recommendations. This presentation highlights some key recommendations for membrane handling, installation, operation and storage conditions.
3:55 to 4:10 – AGC Chlor-Alkali Production, Ms. Motoyama, Asahi Glass
Asahi Glass Company is a world leader in the chemical industry and a leading manufacturer of ion-exchange membranes for chlor alkali production. This presentation will discuss the operation of AGC’s production plants.
4:10 to 4:30 – AGC Technical Services and Support for FLEMION Membranes, Ms. Sasaki, Asahi Glass
Pinholes, impurities and other issues can be seen in used membranes. Mishandling can lead to membrane failure, poor performance and reduced membrane life, which impacts plant operation. AGC will provide examples of commong membrane problems and the possible causes.
9:00 to 9:50 – The Chlor-Alkali Market — A Forward Perspective, Hazel Kreuz, IHS Markit
Multiple forces are converging to create flux in today’s global chlor-alkali market. Forces are shifting in intercontinental trade routes and challenging recent caustic soda price levels. Also, emerging environmental regulations in Northeast Asia are impacting supply, demand and price trends in the global arena. This presentation will explore the key factors that influence expectations for global chlor-alkali trends from now through the early 2020s.
9:50 to 10:20 – Coffee Break
10:20 to 10:45 – Effect of Impurities on Membrane Performance and Recovery of Performance, Mr. Yamaki, Asahi Glass
Membrane durability against brine impurities is critical for stable operation in the IM method. The cross-sectional position of impurities is different for each impurity and their effect on current efficiency and cell voltage. This presentation analyzes how these impurities impact membrane performance and recovery properties.
10:45 to 11:05 – Mr. Ishizaka, Asahi Glass
