For the electrolysis process, the seawater booster pump will pump the seawater to the strainer for filter purpose. The seawater then will undergo the electrolysis process and the gas hydrogen will stored in the degasifier tank.
The cation exchanger and anion exchanger needed to regen every 350m3 of usage while mixed bed exchanger is every 4500m3
The regeneration of the anion exchangers requires caustic soda (sodium hydroxide). During the regeneration, warm sodium hydroxide at 50’C is required; hence the regeneration water heater is used to supply demineralized water at 82’C to the water blender which provides 50’C water to the caustic dilution.
The regeneration of the cation exchangers requires sulfuric acid. The supply of 98% sulfuric acid is stored in demineralizer sulfuric acid storage tanks.
