The maximum chlorine discharge rate as liquid through a 100 Kg. cylinder is 100 Kgs/hr and that of 1,000 Kgs, ton container is 200 Kgs/hr. These discharge rates tend to vary over atmospheric conditions.
Based on leak rate parameters chlorine leak absorption systems are designed for cylinders & ton containers.

At few installations, process conditions are adequate to absorb the leaking chlorine but often emergency during instant and effective neutralisation is required.
When leaking chlorine cannot be consumed in the normal process, neutralisation it with an alkali solution is the best alternative.
The system designed by IEC is a product of 3 decades of experience and expertise in the field of chlorine handling, and tireless research to evolve a simple dependable system.
The absorption tower type chlorine gas scrubber is a dependable cost effective means of neutralizing chlorine.
The scrubber is designed to handle chlorine-air mixture. 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 (from cylinder or ton container) when other means like use of emergency kit does not arrest the 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 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 neutralisation occurs in the packed column by the reaction of chlorine with sodium hydroxide.
Elephant Trunk and Funnel:
During normal operation and maintenance the elephant trunk and funnel allow easy access to leak joints in pipelines and valves for neutralisation. This elephant trunk can be used when the empty ton containers are replaced by the filled ton containers. During such change over operation any leak in the flexible copper tube joints can be drawn by this elephant trunk for neutralisation at the absorption tower.
Emergency Operation: Switch on the pump and blower - The system is ready to rescue! Hood the container - an accident is averted!
Personnel handling chlorine containers should have thorough knowledge and training in safety.
Personnel engaged in emergency operation should use self contained air breathing apparatus and protective clothing. Under no circumstances emergency operations should be undertaken without the aid of an air breathing apparatus.
Air breathing apparatus should always be kept outside the chlorine storage and operating area.
Chlorine leak detectors should be installed at the tonner storage area and the operation room to alert the personnel of chlorine leak.
The chlorine leak detector can also actuate the absorption system automatically, Once the Leak high level set point is exceeded, the detector sends a signal for starting the circulation pump and blower and the system is ready for neutralising chlorine.
The capacity of the alkali tank is sized to absorb leak from a completely filled chlorine container.
After the completion of neutralisation from a leaking container, the solution can be conveniently disposed off as a solution. The resultant solution is highly oxidizing hypochlorite solution. It can also be used as a as a bleaching agent or as a disinfectant.
