| Abstract |
|
Statistical process control (SPC) charts are used to distinguish natural, random variations in a process parameter from fluctuations associated with an assignable cause, such as equipment malfunction or operator error. SPC charts are widely used in industry for quality and process control. In fact, feedback from recent graduates of the undergraduate chemical engineering program indicates that familiarity with SPC charts is one of the most valuable skills for newly hired process engineers. In the following experiment, students are introduced to the concept of SPC through a simple inline mixing experiment. Students learn to create SPC control charts and, more importantly, to understand their function.
