EngrD 2190 Prerequisites• Freshman Engineering Curriculum: an EngrI,
Math 1910, Math 1920, Phys 1112, Intro to CS,and a year of general chemistry.
• EngrD 2190 cannot be taken concurrentlywith EngrI 1120.
• If you intend to major in chemical engineering, you should also be enrolled in Chem 3890.

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.
