If the leak is uncontrollable, the FRP Gas Hood is placed over the Tonner manually to cover the leaky Tonner totally. The outlet nozzle of the Hood is connected to Blower suction by a flexible PVC hose and /or PVC/FRP piping or ducting. The Hood prevents the leaky chlorine gas to spread into the atmosphere.
The Absorbent Pumps and suction Blower/Fans are started [Manually or in Automatic mode]. The Blower sucks the leaked chlorine gas, directs it to the Absorption Tower, where chlorine meets counter currently the absorbent solution. The chlorine gas is absorbed by Absorbent and the air is vented at the top of the tower. As this is absorption accompanied by a chemical reaction, there will be only nil or negligible traces of chlorine in the air vent. The process of starting of Absorbent Circulation Pump and Blower can be done automatically based on the signals from Chlorine Gas Leak Detector sensor[s] located close to the Tonners and in Chlorination Plant.
Sufficient quantity of absorbent is continuously circulated in the Absorption Tower from the Absorbent Tank till the Tonner gets emptied. The spent Absorbent, after completion of neutralisation of all chlorine, will contain only sodium chloride, sodium hypochlorite or sodium sulphate salts which are innocuous. This can be disposed off without any pollution problem.
