Installation of interlock cut-off valves during chlorination process
Thread Content
The company has a chlorine treatment process: the chlorine gas from the cylinders passes through coiled tubes to enter a hot water tank for heating, then goes to a buffer tank before reaching the reaction vessel. When the temperature in the reactor exceeds the set limit, the interlock system activates the shut-off valve for the chlorine gas supply, thereby stopping the flow of gas. I would like to ask everyone the following: 1. How should this valve be selected, what are the specific requirements? 2. Where should it be installed? 3. Are there any other requirements?
The first choice is the FC valve, which serves as the on/off valve for the material inlet. The specific material to be used depends on factors such as the medium, temperature, and pressure, as well as the valve’s response time and other related elements, including the accompanying solenoid valves.
What I really want to ask is about the installation location – whether it should be in front of or behind the heating coil. For drying chlorine gas, a regular PTFE lining should work fine; one with a handle is also an option
Of course, it’s before the coil; it seems to be an important interlock valve as well. In any case, valves that are part of the safety interlock system should not have handwheels, and manual control can be provided by adding hand valves at the front and back.
Installed on the pipeline that supplies chlorine to the chlorination reactor; it should be a pneumatic shut-off valve lined with PTFE, preferably of the FC type with bellows sealing. Give a best answer if it’s good
What is the selection for the cut-off valve of your chlorine reactor at present?
Install this cut-off valve interlock (FC) near the reactor, and simultaneously interlock the valve in front of the heating coil to close as well； If the pressure behind the coil rises, the vaporized chlorine can be discharged into the absorption tank.
