Natural Gas Fractionation Process Facilities Rely On Flow Switch For Relief Valve Leak Monitoring

By Jim DeLee, Sr Member Technical Staff, Fluid Components International (FCI)

A company with multiple natural gas liquid (NGL) fractionation process facilities located in the Southeastern U.S became concerned about a series of missed events and nuisance alarms caused by the flow switches installed to monitor potential overpressure situations with its pressure relief valves. The company wanted a highly reliable flow instrument solution that would detect a real event and avoid the lost productivity of nuisance alarms.
