Presentation Transcript

  1. From Pipeline to Pixel CPAC / NeSSI Workshop 6 May, 2004 Ringmaster: Jeff Gunnell ExxonMobil Chemical Company

  2. What are our objectives when we design an analyser system? • Get a sample out of the process and into contact with an analyser • Make a measurement and check that the result is valid • Send the result to the DCS • Facilitate maintenance

  3. What constraints are we designing to? • Cost of build • Cost ownership • Value added

  4. What are the technologies which we can use? • NeSSI • CoNNI • AppI

  5. Pipeline to Pixel: objectives for today • How to design a NeSSI sample system? • How to connect up the measurement domain? • How to get data through to the DCS? • How to maintain the system?

  6. Using the DoE schematic as an example • Look at the design of the sample system • Celerity, CIRCOR, Parker, Swagelok • Select transducers and components • CPAC web-tool • Review SAM and the measurement domain • Honeywell • Learn about OPC as a connectivity mechanism • Matricon • Consider how to make maintenance easy • Antelope

  7. The DOE schematic • 2 process streams, zero and span • Liquid or vapour process samples • GC or other analysers • Quite a few sample controllers and sensors • Hazardous area • Heaters for substrate and enclosure CLICK FOR SCHEMATIC
