The FLT93L Series FlexSwitch from Fluid Components International is an effective and highly reliable solution for process relief valve leak monitoring demanding petrochemical processes. NGL fractionation processing facilities separate ethane, propane, butane and other heavier hydrocarbons from the natural gas stream. Multiple trains and columns are used in this fractional distillation process, and the relief valves are critical safety protection devices. For the process to work efficiently and safely, the operation requires early and reliable indication when a relief valve leaks or lifts during an overpressure situation. The FLT93L Switch accurately monitors the pressure relief valves for escaping flow with a thermal dispersion technology flow sensing switch/alarm.
