Self-organising smart wireless mesh is overseeing a BP tank farm in Naperville, the Cherry Point refinery in Washington, and is being installed worldwide.
Emerson Process Management and BP continue to collaborate on the application of wireless technology for business improvement. BP has expanded its Cherry Point refinery applications in Washington, installed Smart Wireless throughout its tank farm in its R&D facility in Naperville, Illinois, and is making installations at its other refineries around the world.
First wireless mesh network
BP Cherry Point is a 225 000 bpd refinery, and is the largest supplier of calcined coke to the aluminium industry. Emerson’s Smart Wireless installation on the refinery’s calciner unit monitors bearing and calciner coke temperatures to help prevent fan and conveyor failure. Fans can cost up to $100 000 to repair but, more importantly, can be down for up to 10 days with associated production losses. The 15-transmitter wireless installation in 2006 is believed to be the world’s first industrial wireless mesh network installation, and continues to operate reliably while eliminating operator rounds in the field.
Cherry Point has expanded wireless use to 35 transmitters including tank farm and utility applications, and the installation of a smart wireless gateway in the diesel unit to make it ready for wireless motes.
Wireless is working for BP
“The principal advantage we see around wireless is the ability to accumulate and analyse a much greater array of data than would otherwise be economically possible,” said Michael Ingraham, technical manager for Cherry Point refinery. “Wireless enables us to get more data more efficiently and economically than we have been able to in the past. We really hope our wireless technology will be a principal tool in maintaining plant availability while expanding our flexibility to meet fuel specs and an ever changing array of feedstock.”
A second facility, BP Naperville R&D, is a world-class technology centre including a modernised tank farm feeding an expanding number of pilot plants that develop processing technology options for BP refining worldwide.
Following the first application of smart wireless at the Cherry Point refinery, BP installed a 45-transmitter wireless network at the Naperville tank farm. Operational for about one year, this has provided strong operational experience and a platform for testing the technology, leading to significant take-up of wireless at other BP refineries throughout the world.
“The wireless devices allow our operators to be more efficient, collecting data from one central point as opposed to walking around the tank farm and recording all the values,” comments a BP representative. “The other advantage of the wireless devices is that they supply data continuously for recording in our historian, allowing us to see what is happening in the tank farm at any time of the day.”
The Naperville wireless network uses Rosemount wireless transmitters to monitor suction, and discharge pressures, levels, flow, and temperatures. New wireless functions are installed as they become available, and emphasis is on collaboration with Emerson to expand the capabilities as rapidly as possible to cover refinery-wide applications. The real-world environment, in a pilot-scale operation, provides feedback to Emerson and hands-on experience for refinery management. Options for refinery process optimisation and sharing of wireless automation technology are thereby shared globally by the refining technology team.
“Wireless is an important enabler for refinery of the future technologies,” commented Mark Howard, commercial technology manager for BP. “It helps us deploy the sort of instrumentation, sensors, and analytical devices that we need for condition monitoring to support predictive maintenance, tracking feedstocks through the value chain, and a host of other applications. Wireless is a very important vehicle for getting instrumentation into places where wired devices would be too expensive or frankly not very practical.
“Looking ahead, we support the move towards standards such as WirelessHART,” continued Howard. “We like being able to access new wireless transmitters as quickly as we can deploy them, and we are getting very good robust operation. We look forward to a greater range of instrumentation becoming available.”
Emerson grows through collaboration
“We value highly the collaboration with BP’s refining technology and its refinery of the future team,” said John Berra, president of Emerson Process Management. “Smart Wireless was conceived through years of research and development that led to Emerson’s pioneering introduction to the market in 2006. Key in this effort was the parallel pioneering effort by BP in their trial mesh installation of smart wireless at Cherry Point in that same year. Our combined efforts have I believe moved the age of wireless forward at an accelerated pace.
“We share BP’s important objective of speeding innovation to deliver standard interoperable wireless technology for improved plant reliability, safety and environmental compliance,” concluded Berra.
