ChemCAD 

Provides dynamic analysis of flowsheets using a feature named CC-DYNAMICS, for users who want to design or rate dynamic processes. With CC-SAFETY NET you can combine two-phase relief device calculation to obtain accurate answers. Also, operations like batch distillation simulations can be made.

ChemCAD is a chemical process simulation program that includes libraries of chemical components, thermodynamic methods and unit operations to allow steady-state simulation of continuous chemical processes from lab scale to full scale. You can perform operability check-outs, PID loop tuning, online process control and soft sensor functionalities.
