According to the Statutory Regulations in India and in various countries, it is mandatory to obtain a storage license when five or more chlorine containers are to be stored. Chorine gas even at low concentration is an irritant to mucous membranes and the respiratory system.

Design Capacity: Based on leak rate parameters, Chlorine Leak Absorption Systems are designed. As a standard 1000 kg/hr leak rate is considered for designing the Neutralization system.

System Design:

The system consists of an alkali tank, and absorption tower packed with raschig rings, alkali circulation pump, piping, valves, lightweight FRP hood and flexible PVC duct. In the event of leak, the absorption system would allow the person to breathe easily rather than panic and choke in a polluted atmosphere. The advantage of the system is that the chlorine leak is confined by a hood covering the leaking container and prevents the leakage from spreading. The capacity of the alkali tank is sized to absorb leak from a completely filled chlorine container. After the completion of neutralization from a leaking container, the solution can be conveniently disposed off as a solution.

Operating Principle: The leaking container is covered by a hood. The blower sucks the chlorine gas and delivers to the absorption tower. The caustic solution is pumped counter-currently to the gas flow. Effective neutralization occurs in the packed column by the reaction of chlorine with sodium hydroxide.

Elephant Trunk and Funnel: Allow easy access to leak joints in pipelines and valves for neutralization. This elephant trunk can be used when the empty ton containers are replaced by the filled ton containers.

Safety Accessories: Chlorine leak detectors should be installed at the tonner storage area and the operation room to alert the personnel of chlorine leak.

Disposal: The resultant solution is highly oxidizing hypochlorite solution. It can also be used as a as a bleaching agent or as a disinfectant.
