Rigorous Design and Rating of Distillation Columns

Course Id:  EAP150   |   Duration:  1.00 day(s)   |   CEUs Awarded:  0.7   |   Level:  Introductory


Course Objective

Distillation columns are both capital and energy intensive. The column hydraulic performance is important to ensure high separation efficiency and product quality. Rigorous modeling of columns with hydraulics can greatly improve energy utilization and reduce capital costs.
 
In this course, users will understand how to interactively design and rate distillation columns in Aspen Plus.
 

Audience

Approach

Clear guidance on fundamental topics

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

Prerequisites

Familiarity with process simulation is preferred, but not required.
