Integration of Design and Selected Process Engineering Components into the Unit Operations Laboratory Muthanna H. Al-Dahhan Chemical Engineering Laboratory Washington University St. Louis, MO 63130

Introduction

ABET 2000 criteria require each educational program to include meaningful design experience that grows with the students’ development1. Design of any chemical, petroleum, biochemical, materials, environmental, etc. process involves proper selection and sizing of various process engineering components such pipes, tubes, valves, regulators, filters, pumps, compressors, mixers, instruments, etc. Most of these components are integrated into the set-ups used in a unit operations laboratory. Often the students start the unit operations laboratory without prior experience with or technical knowledge of these components. As a result the students seldom appreciate the need for such knowledge and experience that leads to the proper design, sizing, selection and operation of these components. Since ABET emphasizes the outcomes that are based on practicing profession of engineering, we found it very useful to have one-hour lectures as a part of the laboratory course in which we discuss various process components, their specifications, principles of operation, range of applications, reliability, safety, economic factors, and the basis for their selection in meeting a desired need.

The covered material helps to enhance the knowledge of our students with respect to the design, proper selection, sizing and operation of these components. The course structure provides students with a head start regarding the technical knowledge they need in practicing engineering. Hence, this paper describes the integration of the technical knowledge of various process engineering components into the chemical engineering curricula through the unit operation laboratory to meet the need for engineering practice.

Course Structure

The structure that integrates the technical knowledge of various process engineering components into the unit operations laboratory is illustrated in Figure 1. The technical details of the listed process components are discussed during the above mentioned one-hour lecture session. Since the chemical engineering laboratory courses I and II (ChE 374 and ChE 473) are offered over two semesters, the lectures’ contents are covered over these two semesters according to the schedule shown in Figure 1. The methodology used to select these process components is based on the author’s industrial experience, the extent of their industrial applications, their presence as a part of our laboratory experimental set-ups, suggestions provided by process engineers from
