Abstract

This chapter presents a review of the operating practices at several Beta's manufacturing plants. The company is implementing processes to review the instrumentation and control systems and their maintenance, to ensure process measurement and control capability. Specific improvements for operators, and their training and practices include training in process basics and control limits, and using their expertise to ensure precision control of both the physical process and the chemical process. It also includes use of control and trend charts to measure and trend all key process indicators, physical, and, as necessary, chemical. Training in statistical process control, inherent variability, inherent stability of a given process, and ability to use the knowledge to operate within the basic stable envelope of a given process is suggested in the chapter. The company's plants used a self-audit technique to measure its operating performance and rated itself at just over a 50% level. The company has shifted focus from cost-cutting, per se, to manufacturing excellence and expecting that the costs will come down as a consequence of the best practice.
