Introduction
Chlorine has manifold diverse uses. As its usage and handling rise, the danger associated with it also rises. As such, a potential risk is involved, a severe emergency may suddenly and unexpectedly occur, such eventualities should be anticipated and proper methods should be devised in advance to meet them.
Chlorine Leaks
The leaks in Chlorine Tonner or Cylinder are the leaks around Valves and take-off Flexible Copper Tube Connectors, passing, shearing/breakdown of Valves, puncture on the wall of the Tonner. The common leaks at Valves or Copper Tubing can be met with standard Emergency Kits, but the others will be grave in nature and may suddenly and expectedly happen. It can be extensive and heavy.
PERFECT CHLORO SYSTEM has developed this package system to automatically control and absorb the heavy leaks from the chlorine Tonner based on the recommendations of Chlorine Institute Inc., U.S.A., Bureau of Indian Standards, National Safety Council., Alkali manufacturer's Association of India, lengthy experience of our Technical Consultant Mr. T.N. Balakrishnan, [Former Factory Manager, Mettur Chemicals) and our team of experienced Engineers.
Description
The package system consists of
1. FRP Gas Hood [s]
2. Chlorine gas suction Blower [s] /Fan [s]
3. Absorption Tower
4. Absorption Tank
5. Absorption Circulation Pump [s]
6. Interconnection Pipes, Fittings, Instruments & Valves etc.,
7. Chlorine Gas Leak Detector with Sensor [s]
8. Control Panel
Proper care has been taken in selection of material of construction of equipment, so that they are totally corrosion resistant, reliable and safe.
Process
If the leak is uncontrollable, the FRP Gas Hood is placed over the Tonner manually to cover the leaky Tonner totally. The outlet nazzle of the Hood is connected to Blower suction by a flexible PVC hose and/or PVC/FRP piping or ducting. The Hood pre-vents the leaky chlorine gas to spread into the atmosphere.Alternatively, as a precautionary method the Hood/Hoods can always be placed over the Tonner (s) which is/are in operation.
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.
Absorbent
PERFECT CHLORO SYSTEM's Absorption System employs water solutions of sodium hydroxide as Absorbent for chlorine scrubbing and neutralization. This absorbent will end up with sodium chloride and Sodium hypochlorite as follows,
2 NaOH+C12+H2O NaCl+NaOCI+ 2H20
Using a single chemical as absorbent is easier, shelf life of PCS recommended concentration of Absorbent solution is very high, therefore very reliable, very simple, easy to operate and maintain and also very effective. This is very widely used all over the Country and the World.
Alternatively, PERFECT CHLORO SYSTEM's Absorption System employs water solutions of sodium hydroxide and sodium thio sulphate as Absorbent for chlorine scrubbing and neutralization. This absorbent will end up with only sodium sulphate ,
and sodium chloride as follows
Na2S2O3 + 10NaOH + 4Cl2+ 5H2O 2NaSO4 + 8NaCl + 10H2O
The problem of disposing of the liquid effluent and chance of chlorine escaping from spent absorbent do not come into picture at all in the system.
This Automatic Chlorine Toriner Leak Detection and Neutralisation System is mainly designed to be suitable to standard Tonners. It can also be used for similar emergencies in case of cylinders. Any type of automation as may be required by the Client, can be provided. This system can be also be sized to evacuate and absorb leaks from the entire chlorine tonners storage room, chlorination plant area as whole.
It is a very Comprehensive Safety System and should be necessarily provided where Chlorine Tanners are used.
FRP Full Hood is a robust safety enclosure designed to fully cover chlorine tonners or cylinders, preventing the escape of hazardous gas during operation. It effectively captures and contains any leakage, directing it through ducting systems for safe absorption and treatment. Made from corrosion-resistant FRP material, it ensures durability, reliability, and enhanced safety in gas chlorination systems.
FRP Half Hood is a protective enclosure designed to partially cover chlorine cylinders, allowing easy access while ensuring safety during operation. It helps contain minor gas leaks and directs them for proper handling and treatment. Built with corrosion-resistant FRP material, it offers durability and reliable performance in chlorination systems.
Air Blower is an essential component used to provide a steady flow of air for ventilation and gas handling in chlorination systems. It helps in safely directing leaked chlorine gas towards absorption units, ensuring a secure working environment. Designed for high efficiency and durability, it delivers reliable performance in industrial applications.
Caustic Recirculation Pump is designed to circulate caustic solution efficiently within chlorine gas scrubbing systems. It ensures continuous neutralization of hazardous chlorine gas by maintaining proper chemical flow and pressure. Built with corrosion-resistant materials, it delivers reliable performance and long-lasting durability in harsh industrial environments.
Control Panel is the central unit used to monitor and manage the operation of chlorination and safety systems. It ensures smooth control of equipment like blowers, pumps, and alarms for efficient and safe functioning. Designed for reliability and ease of use, it provides precise control and enhanced operational safety.
Chlorine Leak Detector is a safety device designed to continuously monitor and detect the presence of chlorine gas in the environment. It provides instant alerts in case of leakage, helping to prevent accidents and ensure worker safety. Built for high sensitivity and reliability, it is essential for maintaining a safe and controlled chlorination system.
Tower is a key component in chlorine gas scrubbing systems, designed to absorb and neutralize hazardous chlorine gas using caustic solution. It ensures efficient gas-liquid contact for effective removal of toxic fumes before releasing clean air. Built with corrosion-resistant materials, it offers durability and reliable performance in industrial environments.
Tank is used for storing caustic solution required in chlorine gas scrubbing systems. It ensures a steady supply of chemical for effective neutralization of hazardous chlorine gas. Made from corrosion-resistant materials, it provides safe storage, durability, and reliable performance in industrial applications.
