Steve Hendon – Chief Technology Officer & Founder
Steve Hendon is Vice President Engineering & Development and co-founder of eSimulation, Inc. He has more than 33 years of experience in the development and implementation of real-time optimization (RTO), multivariable control, and business modeling software for the refining, petrochemical, gas processing, and NGL industries.

Prior to forming eSimulation, he worked for Exxon Chemicals, Dynamic Matrix Control Corporation (DMCC), and Aspen Technology. While at DMCC from 1989 to 1996, he implemented the first rigorous equation-based process model library, PML, for real-time optimization. This software revolutionized real-time optimization by reducing the project development and implementation time from years to months and further reduced maintenance costs through the standardization and improved robustness of the models. In addition to the RTO projects while at DMCC, he also implemented DMC multivariable control projects and pioneered many new DMC features such as imbalanced ramps and sub-controllers.

During his time at DMCC and AspenTech, Steve was project leader for the implementation of RTO and DMC multivariable control on crude units, FCC units, catalytic reformers, aromatics plants, phenol plants, and BPA plants,

In 2000, while at eSimulation, he designed, developed, and deployed the first cloud-based SaaS RTO system, eSimOptimizerTM, on an NGL cryogenic processing plant in Oklahoma. Since then, with a small team of chemical and software engineers, more than 40 cloud-based SaaS RTO applications have been implemented on both NGL cryogenic processing plants and NGL fractionation plants. In 2006, the midstream business modeling system, eSimEvaluatorTM, was developed and released.

This software combined the equation-based optimization solving engine with a visual front-end, case study tools, sensitivity analysis and a SQL database. eSimEvaluator is used for midstream budgeting, forecasting, accruals, and super system optimization. In 2014, Steve and his team worked with their client, to design and implement eSimGatheringTM, a cloud-based platform for digitizing midstream companies gathering asset data. Applications include condensate and water, greenhouse gases, pipeline pigging pipeline compression, and facility data.

Steve graduated from the University of Oklahoma in 1984 with BS in Chemical Engineering. He has written many papers on Real-Time Optimization and Advanced Process Control and has spoken at many refining, chemical, and natural gas industry events.
