Condensers Short Course (US$650)

Instructor: Andy Mountford

Learn the fundamentals of condensation mechanisms and how they apply to condenser design! Apply guidelines to develop Xchanger Suite cases for accurate assessment of performance. This course provides a foundation for understanding the basis for thermal design of typical industrial heat exchangers.

Key Topics

  • Film condensation of pure components
  • Relationship between pressure drop and saturation temperature
  • Condensing flow regimes: Vertical units/Horizontal units, tube side and shell side
  • Specifying pure component condensers in Xist
  • Noncondensables and mixture condensation
  • Specifying mixture condensers and inerts in Xist
  • Vapor phase coefficient
  • Desuperheating and subcooling
  • Bulk-equilibrium vs. two-layer subcooling model
  • Venting inerts
  • Drainage
  • Baffle design in condensers
  • Condensation with enhanced heat transfer surfaces
  • Vacuum condenser design challenges
Suggested Participants
