Emerson has introduced wirelessly-monitored Enardo 2000 emergency pressure relief vents (EPRVs) that 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.

“Though EPRVs represent the last line of defence against tank overpressure, they have largely remained unmonitored,” said Steve Attri, product manager for Emerson Process Management. “Along with the recent introduction of wirelessly-monitored pressure vacuum relief vents (PVRVs), more information is now available to quickly identify and resolve pressure issues that can impact safety and emissions.”

In other Emerson-related news, the company has introduced the Paine 310-38-0050 Series Transducer to provide increased reliability when making pressure and temperature measurements in downhole oil and gas drilling and production operations. The transducer has the smallest footprint available with an outside diameter of just .93 centimetres (.37 inches) to save critical downhole tool space.

Downhole drilling operations must measure pressure, temperature and other variables to optimise the drilling process and ensure safety. These measurements are typically made with a variety of downhole tools, either mounted just above the drill bit to provide continuous measurement while drilling, or as separate tools inserted into the drill hole on a periodic basis. Once drilling is complete and production begins, these measurements are needed to optimise throughput, maximise uptime and ensure safety.

In all of these applications, space is at a premium and high reliability is required. The environment is extremely harsh with high temperatures and pressures, corrosive drilling fluids and high vibration. Rugged components with small form factors are required to support smaller tool sizes, along with increased pressures and temperatures as holes become deeper.

To address these issues, the Paine 310-38-0050 transducer provides both temperature and pressure measurements in the smallest and most rugged form factor possible. It supports measurements up to 25kpsi (1723 BAR) and temperature up to 425F (218C) to cover the wide range of downhole operating environments.

The 310-38-0050 transducer provides well operators with critical pressure and temperature data for smoother and more efficient downhole operations with increased reliability and reduction of downtime. It improves upon prior solutions by offering a much smaller form factor while still providing the required measurements.

MICRO MOTION APM

Emerson Process Management also launched its Micro Motion Advanced Phase Measurement (APM), a software option available on the Model 5700 Transmitter. The software solution helps improve measurement accuracy across diverse industries in challenging multi-phase applications such as direct wellhead and separator net oil measurement in the oilfield and starch concentration for food and beverage plants.

This multiple phase measurement solution provides insight into the complete flow stream, including oil, water, and gas, through an intuitive, local display. Leveraging Emerson’s years of experience in providing solutions for process upsets or intermittent two-phase flow, Advanced Phase Measurement provides continuous, real-time production data for oil, water and gas void fraction.

“Advanced Phase Measurement was designed with production engineers in mind, providing insight into production trends with a single device to reduce capital and operating expenses,” said Kevin Borden, product manager. “You can track whether production is increasing or decreasing, allowing proactive management of changing field performance which ultimately equates to more dollars in your bottom line.”

Advanced Phase Measurement has also proven useful for the life sciences and chemical industries, providing critical measurement insight to reduce waste, maintain product quality, and identify process upsets even in the presence of multiple phases.
