Continuous Sodium Hypochlorite Process Systems
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
Dry Liquid or Vapor Chlorine Bleach Plant
This bleach plant is available in two basic 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
Wet Vapor Chlorine from Electrolytic Cells
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. More about Wet
