New Software Package for Improved Chemical Plant Operations

Research output: Patent


Precise control of the operating parameters in chemical processing plants from refineries to fine chemical manufacture as well as a myriad of other products is critical to both the manufacturing efficiency and consistency of product quality. For this purpose, a system of accurate sensors and real time software analysis can accomplish that objective. However, due to uncontrollable fluctuations and response times, there are limitations in the degree of control that can be attained.Researchers at Arizona State University have devised a new software system that, through appropriate mathematical analysis, achieves a new and much more refined generation of process control. Dubbed "ASUtune", this software provides an interactive menu-oriented package that enables process control engineers to integrate the tasks of system identification with controller tuning for PID-type controllers. This new software package provides for:> Integrating system identification and PID controller design> Allowing PID design directly from plant data> Enabling PID design under high noise / drifting conditionsOnce input-output data is entered, the program will guide the user through the set up of the process model. ASUtune will then work with the control system to insure the smooth running of the process. ASUtune can be expected to improve the process for better, & more consistent product quality and reduced operating costs as a result of higher efficiencies.
