EngrD 2190 - Chemical Process Design & Analysis - Course Objectives

OverallTo introduce chemical process design and analysis.

Engineering SkillsTo design a chemical or biomolecular process by the following steps:

define the real problemgenerate ideascreate a designanalyze the design.

To analyze a chemical or biomolecular process with three methods:

mathematical modelinggraphical modelingdimensional analysis / dynamic scaling.

“I have had the privilege of being a Cornell graduate with a degree in engineering. I credit much to my career success to being an engineer by training. Engineers solve problems and fix things.”

“Chemical Engineers are just like regular people … only smarter.”
