Continuous Sodium Hypochlorite Process Systems

Advantages

Bleach Plant

The Powell Continuous Sodium Hypochlorite Process System, also referred to as a Bleach Plant, is designed to manufacture sodium hypochlorite with greater efficiency and higher quality than previously obtainable with batch or continuous methods.

The process, which uses liquid or vapor chlorine and caustic, is versatile and has the design capability of making any concentration of sodium hypochlorite solution from 20 to 200 grams per liter available chlorine.

The bleach plant is constructed of high quality components to ensure long service life with a minimum amount of maintenance. In addition, mechanical refrigeration is not required to cool the process. Titanium plate heat exchangers utilize water from a cooling tower to cool the process. The unit is housed in a structural steel frame so that it can be completely fabricated in our factory and easily shipped as a complete unit to your site.

The continuous process system also eliminates the need for mechanical refrigeration which is typically required when bleach is produced by other methods. The system utilizes cooling tower water for cooling resulting in considerable energy savings, lower equipment costs, and lower maintenance costs.

Powell Continuous Sodium Hypochlorite Process Systems can be designed to use pressurized dry liquid or vapor chlorine or wet vapor chlorine from electrolytic cells.

Wet Vapor Chlorine from Electrolytic Cells

This system utilizes wet vapor chlorine directly from electrolytic cells. Standard systems are designed to produce concentrations from 125 to 200 grams per liter available chlorine with production rates from 40-150 gallons per minute which is equivalent to 50-200 STPD of chlorine.

Dry Liquid or Vapor Chlorine Bleach Plant

This bleach plant is available in two designs:

  • utilizes pressurized dry vapor chlorine
  • or utilizes pressurized dry liquid chlorine.

Standard systems are designed to produce concentrations from 20-200 grams per liter available chlorine with production rates from 25-150 gallons per minute which is equivalent to 30-200 STPD of chlorine. More about Dry Liquid or Vapor System Bleach Plants
