Ensure Process Safety with BLOWDOWN™ Technology and PSV Sizing in Aspen HYSYS

Course Id:  EHY107   |   Duration:  1.00 day(s)   |   CEUs Awarded:  0.7   |   Level:  Introductory

Course Objective

The course will demonstrate how to use some of the latest features in Aspen HYSYS to design and rate blowdown valves, pressure safety valves and pressure vacuum vents. The course is primarily workshop-based with an introductory lecture and demonstration. We will allocate time for our staff to answer specific questions that have been submitted prior to the course.


Process engineers who want to optimize their process while considering the process safety implications of any modifications. The session will employ a hands-on approach to understand how various simulator functionalities support the process safety workflow.


Clear guidance on fundamental topics

  • Industry workflows
  • Hands-on workshops
  • Experienced instructor-guided demonstrations
  • Q&A on student-specific problems


Familiarity with process simulation is preferred, but not required.
