Abstract
The present invention relates to a system (100) and method for recovering sodium hypochlorite from exhaust chlorine gas. By using the system (100) and method of the present invention harmful chlorine gas exhausted, can be recovered as useful sodium hypochlorite solution for further use without discharging the gas to atmosphere. One of the advantages of the present invention is that it eliminates exhaust chlorine gas as scrubbing waste discharge and without a need for cost required for setting up a waste water treatment system. Instead, it recovers sodium hypochlorite solution which is very useful and of high demand in the market. One skilled in the art will also appreciate that the final product produced from the system of the present invention can be used for performing numerous applications.
