Special Topics in Xist Short Course

Course Fee: US$650

This short course moves beyond the fundamentals of thermal design to focus on specific design challenges associated with a range of service types including viscous shellside coolers, feed-effluent exchangers, kettle reboilers, and vacuum condensers. Presented as a series of case studies, each topic is introduced by the instructor before participants delve into Xist to work on solutions which are ultimately discussed amongst the group. The knowledge attained from this short course will allow you to tackle related design challenges in your future work.

Key Topics

  • viscous shellside coolers
