Modern Lab Experiments for Chemical Engineering

Abstract

We describe new experiments developed, and installed, to bring our chemical engineering laboratory into the 21st century. These additions are:

(1) Compact disc write and re-write systems (2) Fluidized bed polymer coating (3) Hydrogen fuel cell and hydrogen storage (4) Photocatalytic water purification (5) Rapid prototyping via ink jet printer (6) Silicon wafer oxidation

These new experiments collectively allow introduction of topics which are modern, yet not routinely covered in traditional chemical engineering laboratories. The experiments described are relevant to energy storage and utilization, polymer coating of consumer and microelectronics products, water purification, laser-driven material transformations for information storage, semiconductor circuit fabrication, and computer-aided solid prototype synthesis.

Introduction

In changing times, the keepers of engineering curricula must look to the most responsive academic elements to address new needs. We believe that the future of chemical engineering lies not only in biotechnology, but also in many other arenas, including electronic and photonic materials and devices. As the time needed to create a new lab experiment is mere months, whereas creation of new a text takes years, it follows that in times of change, our laboratories should be leading, rather than following, curricular changes. We report here the installation of six experiments which, taken together, substantially enlarge the range of experiments in our undergraduate ‘unit operations” and “transport phenomena” laboratories. The chemical engineering undergraduate laboratory has traditionally existed to satisfy either or both of the following objectives: (1) illustrate individual unit operations (e.g.,extraction1, mixing2, chromatography3, adsorption , electrochemical deposition6, fluidization7) 4,5
