Chemical process units such as reactors, superfractionators, furnaces, compressors and many other types of rotating equipment etc; have a handful of critical primary control loops that warrant reliable oscillation detection and timely protection. Online oscillation detection and automatic adaptive control action can arrest the onset of incipient oscillations that could have eventually grown and caused the entire process to oscillate. Many modern processes today are heavily heat and mass-balance integrated using recycle streams and integrated heat exchangers. This integration make the processes even more vulnerable to plant or process-wide oscillations. If oscillations pass unnoticed and grow, it is extremely difficult to identify the source of the oscillations, since all process variables seem to be oscillating. The new, revolutionary TAD algorithm inside the TADPOLE software product provides a powerful and reliable way to suppress the oscillations and restore process stability quickly.
