Agenda CHEMCAD Basic Seminar

posted in: Agenda 0

Day 1

The first day introduces the major elements and some typical workflows with a special focus on separation processes involving the vapor and liquid phase such as the 2-phase flash and distillation.
Basic thermodynamic concepts are covered together with the most important gE-models and equations of state. Due to the importance in distillation, some general rules and simplifications concerning azeotropic behavior as well as options for the separation of close-boiling or azeotropic mixtures are discussed.
The greatest part of the day is occupied by workshop examples to let the participants become familiar with the user interface and the basic workflows of CHEMCAD.

Day 2

The second day covers a variety of topics, mostly in form of practical workshops starting with important tools like sensitivity studies and optimization and coverage of recycle stream convergence and physical property estimation.

After final workshops on distillation and column sizing, the afternoon features brief hands-on introductions to dynamic simulation, chemical reactors and heat exchangers. An outlook on further features and advanced courses and a final discussion and evaluation conclude the course.
