Introduction

Process instrumentation and control has been an integral component of the chemical engineering curriculum for the better part of three decades. However, the changes that have occurred in instrumentation and automated control during the past decade are significant. Many departments have been faced with the need to augment the traditional instruction of this subject with laboratory experiences so that their graduates are conversant in state-of-the-art instrumentation and control as it is practiced in industry today. These laboratory experiences allow the student to gain an appreciation for the contribution these tools make to the successful operation of a process unit or plant, to become familiar with instrumentation, and to be exposed to advanced control strategies in practice. This paper describes efforts at Mississippi State University to transform the process control instructional methods to facilitate the transition from undergraduate student to practicing engineer in the area of process control.

The Dave C. Swalm School of Chemical Engineering has established a process control laboratory to provide a laboratory-based experience with industrial style controllers for its undergraduates. The system chosen as the foundation of this laboratory is the CAMILE Data Acquisition and Control System (Sagian, Inc.)

Description of the Laboratory Facility

The process control laboratory is comprised of 7 work-stations, each comprised of a CAMILE 2201TG Data Acquisition and Process Control System, a Pentium-based PC, and a custom-built Pyroluminescent Regulometer. Each CAMILE 2201TG is equipped with a 10 Hz, 8 channel Multi-sensor board, a 10 MHz, 8 channel Analog Output board, and a 10 MHz, 32 channel Digital Input/Digital Output board. The multi-sensor board allows one to monitor a wide variety of input sensors including thermocouples and other temperature measuring devices, flowmeters, pressure sensors, and pH sensors. The analog output channels can be used to position valves, regulate agitators and variable speed pumps as well as other devices. The digital input/output channels can be used to monitor on/off devices and control heaters, valves, and pumps. The CAMILE system is an integrated hardware/software package, with the software operating in the Windows environment. Because of the familiarity of students with the Windows operating system, the student learning curve for operation of the CAMILE TG software is significantly reduced.
