High Current Efficiency (C.E.) is key to profitable chlor-alkali production. Being able to determine how each of your cells are performing in terms of Specific Power Consumption (SPC) gives you the edge needed to get ahead in this competitive field.

We provide the ability to gain this edge by giving you a window into your asset data in order to effectively predict and characterize each component of an electrolyser (anode, cathode and membrane).

Make the best replacement decision

We recommend that you base your decision to replace or to keep a component on the individual economic performance of each component and the cost of replacing it. If a component costs more to operate than to replace, it should be part of your next maintenance program. If not, it should be kept in place. This means:

• Get rid of underperformers = Higher Current Efficiency = Energy Savings and/or More Output
• Keep your over-performers = Extended Component Life Time = Lower Maintenance Costs

The EMOS^® Cell Performance Analyzer (CPA) is a service which determines the precise performance and economics related to the operation of electrodes (U0, k-values) and membranes (k-value, C.E.) of single electrolysis cells.

CPA CASE STUDY

The following case study used a new plant with 8 electrolysers over a 10 year period. Each electrolyser has 175 cells, for a plant total of 1400 cells.

The first graph shows the savings in Specific Power Consumption (SPC), while the second shows the reduction in replaced components from a total of 1440 components replaced after 4 years without R2, down to 658 components replaced with R2 after 4 years. Both savings are due to using the EMOS^® Cell Performance Analyzer service.
