Transcript

  • 1. Application of Acoustic Vibration to Overcome Wax Deposition in Piping<br />Neelendra Nath<br />SPE MembershipNo.3319219 <br />Maharashtra Institute of Technology, Pune<br />
  • 2. Overview <br />Introduction<br />Wax Deposition: Cause and Concern<br />Prevention Techniques<br />Proposed Solution<br />Science Behind Technology<br />Wax Deposition Modeling<br />Prevention Modeling<br /> Tool Parameters<br />Conclusion<br />
  • 3. Introduction<br />
  • 4. Wax Deposition: Cause and Concerns<br /><ul><li> Microcrystalline Content of Crude
  • 5. Temperature in the flow line: Cloud Point
  • 6. Flow Rate
  • 7. Flow Velocity
  • 8. Flow Direction: Vertical or Horizontal
  • 9. Scaling
  • 10. Reduced Production
  • 11. Accentuate Corrosion</li></li></ul><li>Prevention Technique<br />
  • 12. Proposed Solution<br />
  • 13. Science Behind Technology<br />
  • 14. Wax Deposition Modeling<br />Vd= f{ T, C, V, Q, v}<br />where, T  Temperature<br />C Paraffin Concentration<br />V  Flow Velocity<br />Q  Flow Rate<br />v  Drift Velocity<br />Concentration  Can be altered by additives<br />Flow Rate & Flow Velocity  Can be controlled but multiple constraints apply<br />Drift Velocity  Dependent factor<br />Temperature  Most easily altered, shows immediate results  “OUR CANDIDATE”<br />
  • 15. Prevention Modeling <br /> OUR CANDIDATE  Temperature<br /> T = f{Q, h, k, S}<br />Controlled Parameter  Q<br /> Q = f{E, c}<br /> c  Damping Co-efficient (Constant)<br /> E = Area under Hysteresis Loop<br /> = f{ f , Y}<br />* Shearing Strength of Material is a major constraint <br />T > Cloud Point<br />
  • 16. Tool Parameters<br /> AC Input<br />Charging <br />Tool Positioning<br />Damper Requirement<br />Shielding & Focusing<br /> Temperature Sensing<br />Frequency Range<br />Material Selection<br />
  • 17. Conclusion<br /> Simple Mechanism<br />Extremely Cheap<br /> Do away with thermal jacketing <br />If surface controlled can be utilized for multiple application<br />Complete solution <br />
  • 18.
