Emerson Process Management’s Smart Wireless technology is helping RWE Gas Storage maximize the capacity of its Dolní Dunajovice underground gas storage facility in the Czech Republic.
According to Emerson, the installation of five Smart Wireless networks and more than 100 wireless measurement devices has increased visibility into the process, enabling the plant to improve control and run closer to its capacity.
Automating data collection has also eliminated manual rounds at the plant, improving operator efficiency and safety.
RWE needed a solution that did not require installation of new cabling and allowed a longer period for the upgrade to be completed. To meet this need, RWE selected Smart Wireless technology from Emerson. Based on IEC 62591 (WirelessHART®) communications, the technology is well-proven, reliable and both quick and easy to install and commission.
Five wireless networks span the entire 50,000-square-metre facility, supporting more than 100 new wireless transmitters. The instruments are predominantly Emerson’s Rosemount® wireless pressure and temperature transmitters, with a number of Rosemount Guided Wave Radar level transmitters and Fisher control valves also connected using Emerson’s THUM™ Adapters.
“Emerson’s wireless solution takes only a quarter of the time to install, and saves around 20 percent of the cost of a cabled installation,” continued Pavel Silinger, Energy Manager, RWE Gas Storage s.r.o. “The availability of HART® data, including diagnostics from new and existing devices, was another significant reason for selecting Smart Wireless and is helping us to improve plant maintenance procedures.”
Based on the successful implementation of wireless technology at the Dolní Dunajovice site, RWE plans to implement Emerson’s Smart Wireless at all of its underground storage facilities in the Czech Republic.
RWE Gas Storage, part of the RWE Group, is the biggest underground gas storage operator in the Czech Republic, operating six facilities with a total operating capacity of almost 3 billion cubic metres. Gas is stored in porous underground facilities during low-off take periods and supplied to users when demand peaks.
