 Department of Chemical Engineering 
 Brigham Young University
 Provo, UT 84602 

John Hedengren is Associate Professor at Brigham Young University in the Chemical Engineering Department, leading the PRISM (Process Research and Intelligent System Modeling) group. Prof. Hedengren teaches courses on computational methods, process dynamics and control, optimization, dynamic optimization, and fundamentals of chemical engineering. He is a chemical engineer by training with a B.S. and M.S. degree from Brigham Young University, and a Ph.D. from the University of Texas at Austin.

Prof. Hedengren has consulting experience with Apache, ENI Petroleum, HESS, SABIC Ibn Zahr, TOTAL, and other companies on automation solutions. He worked full-time for 5 years with ExxonMobil supporting advanced control and optimization solutions. His industrial control experience with PLC and DCS systems includes OPTO22, Honeywell TPS/TDC3000, Experion system, OPC, and Modbus. His area of expertise is in process dynamics, control, and optimization with applications in fiber optic monitoring, automation of oil and gas processes, unmanned aerial systems, systems biology, and grid-scale energy systems. In chemicals manufacturing, he has extensive experience in automation and modeling of the production of polymers such as polyethylene, polypropylene, butyl rubber, and polystyrene as well as specialty chemicals (polyalphaolefins). Automation software (APMonitor) that he developed has been applied in over 100 industrial applications world-wide in refineries, chemical plants, and offshore oil platforms.

Research Interests

  • APMonitor Software: Advanced Process Monitoring (APM) is a software platform to solve large-scale Differential and Algebraic Equation (DAE) models in simulation, process control, and optimization applications. Recipient of the 2014 AIChE David Himmelblau Award.
  • Applications in Process Systems Engineering
    • Drilling Automation
    • Energy System Optimization
    • Model Predictive Control
    • Unmanned Aerial Systems
  • Nonlinear Model Library: One of the major bottlenecks to improved nonlinear Model Predictive Control (Nonlinear MPC) and Real-time Optimization (RTO) is the lack of reliable first-principles or hybrid models. This nonlinear model library is a collaborative platform where chemical process models can be documented and shared.
