Pressure relief valves are essential in keeping process manufacturing and production operations safe and operating reliably. But, as environmental regulations grow stricter, knowing how much fluid was vented is vital for regulatory reporting.
In this under three-minute YouTube video, Anderson Greenwood & Rosemount Pilot Operated PRV Monitoring Delivers Unparalleled Accuracy, Emerson’s Ricardo Garcia shares how monitoring pressure relief events help operators gain additional visibility into their process while adhering to incrementally important environmental standards. Undetected pressure relief events can lead to issues relating to safety, emissions, reliability, and productivity. Pressure relief valves have historically been “off-grid.” Still, changes in environmental regulations, in conjunction with an increased interest in efficiency and productivity, are driving the need to monitor pressure relief events.
Ricardo shows how this pressure relief valve (PRV) monitoring solution with Anderson Greenwood high-pressure and low-pressure pilot valves includes the choice of a Rosemount 3051 or 2051 differential pressure transmitter. It monitors the differential pressure between the pressure pickup port and the main valve dome. The differential pressure between these two points directly correlates to the valve lift percentage. This capability, paired with an Anderson Greenwood modulating style pilot valve, is the most accurate way to monitor, record, and report the volumetric flow during a pressure relief event.
Ricardo explains the benefits of pilot-operated PRVs over conventional, direct-spring PRVs. These benefits include a soft-seat design that provides bubble-tight performance before and after each relief cycle. They have increased seating forces as the valve approaches its set pressure. These pilot-operated relief valves are balanced against the effects of back pressure. They are available in pop or modulating action, which can significantly reduce product waste and environmental emissions.
