Chlor Alkali Anode & Equipment's f

Reason

Impact

Damage

Over Voltage (Potential)

Surface coating resistance is the cause for Over Voltage. 

Higher power consumption

leads to higher operating

cost.

Alkali Wear Resistance

Resistance to loss of Metal Oxide, the critical catalytic element during operation.

High alkali wear leads

shortage in anode life, or

add more metal oxide during coating.

High Chlorate in brine

During Cl2 production, ClO^-₃ is produced as a by-product.

Potentially environmentally damaging and discharge

may be limited.

Higher chemical usage in

chlorate destruction system.

Higher rates of corrosion in

caustic evaporators as

higher levels of chlorate in c

austic soda.
