  1. The Wireless Refinery? By David Land, P.E. ConocoPhillips Field Instrumentation Network Lead

  2. Presenter • David Land, P.E. (CSE)  • Field Instrument Network Lead • ConocoPhillips • Downstream (Refining) • Bachelor of Science in Physics from Oklahoma Baptist University • Masters in Instrumental Science from University of Arkansas • 30 years with Conoco and ConocoPhillips all in the Instrumentation field • 25 years at the Ponca City Refinery as Instrumentation Reliability Engineer • 30+ years as an ISA member • 25 years as a Senior ISA Member • 27 years as a licensed Amateur Radio Operator

  3. Existing Wireless Applications • Mostly Tank Farm Applications: • Tank level signals back to the control room via various wireless methods. • Networks: RTU communications via wireless link instead of wire • 4-20MA: Analog signals via wireless link instead of wire • Independent High Level Alarm systems. • Point to Point wireless devices wired to top of tank level switches • MultiPoint wireless devices wired to top of tank level switches • Some with Solar Chargers and batteries to eliminate AC power wiring costs • Butane and Propane Spheres • Monitor pressures with wireless pressure transmitters to replace operator rounds

  4. Existing Wireless Applications • Relief Valve Applications • Monitor with acoustic sensor to indicate vapor releases • Analyzer Applications • Wireless links to provide data and diagnostic interface to analyzers • Remote Firewater Pump Control • Redundant Wireless links to start Firewater pumps on low pressure elsewhere in the plant’s firewater system

  5. Existing Wireless Applications • Emergency Alert Systems • Pagers for everyone onsite to warn for any emergency • Instant access to all personnel • Remote Operator Interface • Wireless network to operators in tank farm areas for quicker response to alarms • Video • Video security via wireless links to reduce capital costs • Flare Monitoring • Flare flowmeters via wireless back to control system

  6. Existing Wireless Applications • Cavern Area • Control Room to Operator’s Pickup via wireless link • Area Gas Monitoring • Remote beacon lights controlled via redundant wireless links from widespread gas monitors to warn of releases • Fence line Monitoring • Wireless links to gas monitors along the outside fence line

  7. Future Wireless Applications • Heat Exchanger Monitoring • Wireless temperature measurements on the inlet and outlet of various heat exchangers to monitor for fouling and efficiency. • Coker Valve Monitoring • Wireless valve position monitors to prevent operator errors on valve sequencing

  8. The Wireless Refinery? • Greenfield Applications • Use wireless instruments on ALL non-control measurements • This would be about 50% of all instruments in a typical Refinery • Control is around 20% of the total, the other 30% is miscellaneous that probably won’t go wireless. • Would result in 25 to 40% capital reduction for the instrumentation phase

  9. The Wireless Refinery? • Brownfield Applications • Use wireless instruments on ALL non-control measurements of future expansions • This would be about 50% of the instruments on a project • Would result in 25 to 40% capital reduction for the instrumentation phase

  10. The Wireless Refinery? • The Future: • 5 to 10 years from now, wireless will be like cell phones are today. Can you remember how we got along without cell phones? How did we get anything done? Wireless Instrumentation will be the same way. • Questions?
