How to determine the treatment capacity for chlorine handling systems in liquid chlorine tank farm accidents?
Thread Content
Currently, liquid chlorine storage areas are required to be enclosed and equipped with negative pressure suction systems as well as devices for handling accidental chlorine releases. However, it is unclear how to determine the processing capacity of such devices for dealing with accidental chlorine releases Are there any calculation methods or standard guidelines? I hope fellow sailors can give me some advice.
Calculate the safe operating time based on the maximum inventory of absorbed alkaline solution and the maximum chlorine release amount
Is there any design basis? How are the leakage amount and leakage rate determined? With these two points uncertain, how can design be carried out?
Since both the amount of leakage and the leakage rate are uncertain, in practice I think accident chlorine handling systems are more of a help than a hindrance, especially now that all systems are becoming larger in scale and the capacity of liquid chlorine storage areas is very high. I prefer to use a horizontal liquid chlorine storage tank that is always kept empty, connected via pipeline valves, as a transfer tank for emergency storage tanks; this allows for the maximum possible transfer of liquid chlorine from the emergency tanks. Only by combining this approach with an emergency chlorine treatment system can that system truly fulfill its role, while also accelerating the processing of the liquid chlorine in the emergency tanks.
