Reducing moisture in liquid chlorine storage and piping.
This analysis shows how small trace of moisture in the dry chlorine increases the operation cost of the plant, and issues a set of recommendations to keep the moisture out and curb the up-creep in maintenance cost due to the accumulation of ferric chloride scale in the system.

Avoiding failure of start-up feed caustic valves due to electric current.
The electric potential across the start-up feed caustic valves often causes the destruction of these valves due the Joules effect on the conductive path created by small leaks of caustic soda. Replacing a burned-out valve during production is impossible, as it requires to completely drain-out the electrolyzer. Special valves including by-pass electrodes and an external current breaker have been designed to solve this problem.
