Production of Sodium Hypochlorite

Sodium hypochlorite can be produced by reacting chlorine and sodium hydroxide solution. It can provide a by-product from the chlorine vented when organic chlorination is carried out. The ATR ASAHI plant carries out a batch operation and the required quantity of sodium hydroxide solution is charged to the recycle tank and circulated around the reaction column. The reaction column incorporates a packed section to contact the sodium hydroxide and chlorine, together with heat exchangers to remove the heat of reaction. The plant will produce sodium hypochlorite solution containing 14-15% available chlorine corresponding to approximately 16% by weight of sodium hypochlorite.

ATR has the capability of supplying 10 T/Hour plants. The storage tanks are usually made of CPVC-FRP for NaOCl storage. The recirculation tanks are made of PP-FRP. We use Glass Shell and tube heat exchangers for heat transfer. The pumps are of PPH with FLP motors. Venturi scrubbers and PP Ejectors are used as required. The interconnecting piping is of CPVC. We also provide single stage scrubber system for chlorine evacuation. The plant is then completed with automation and control instruments.
