New wirelessly monitored storage-tank emergency vents

By Chemical Engineering |

The new wirelessly monitored Enardo 2000 emergency pressure-relief vents (EPRVs; photo) provide safety control by managing abnormally high storage-tank pressures in the oil-and-gas, chemical, petrochemical and pharmaceutical industries. Under normal operating conditions, an EPRV remains closed. The immediate knowledge of an open position can be vital and should warrant quick investigation. However, because these EPRVs are located on top of storage tanks, they are difficult to monitor. Site managers are increasingly looking for ways to increase safety and efficiencies. The new product design consists of a proximity indicator and wireless transmitter integrated with an EPRV. The proximity indicator senses movement of the emergency vent. “Open” or “closed” signals are received by the wireless transmitter and can be sent to a control room via a WirelessHART gateway. — Emerson Process Management, Austin, Tex.
