*Greg*: Early in my career while I was the lead instrument and electrical engineer on what at the time would be the world’s largest acrylonitrile plant, I found the compressor control systems most challenging because of how fast things could go wrong and shutdown the plant. I had a degree in engineering physics with electives in chemical engineering but nothing prepared me for what I needed to know in terms of control system setup and dynamics. In my spare time I built a dynamic model of a compressor system. It changed my life. I developed a much better understanding of causes and effects and an appreciation of dynamic modeling as an essential learning experience. It caught the attention of the process control group in the Engineering Technology (ET) section. At the end of the project, I was offered a job in ET with what were the best minds in developing software for process design and writing dynamic models for process control. Forty years later, I'm still making the most out of the synergy between dynamic modeling and control. Most of my deep understanding of process dynamics stems from building and using dynamic models.
