Dr. Dhaval Dave has 14 years of experience in simulation and optimization in a variety of industries. He currently works for Schneider Electric as a Senior Consultant in the Design, Simulation and Optimization group. His prior experience includes positions with British Petroleum and Aspen Technologies. He holds a PhD in chemical engineering from the University of Manchester, UK and an M.Tech from the Indian Institute of Technology - Kanpur. His main expertise is in Dynamic Simulation and Real Time Optimization.
A petrochemicals boom is currently under way in the USA because natural gas prices are expected to remain low for the foreseeable future due to technological advances in extracting gas from shale. By 2Q 2018, an additional 15.6 billion lb/yr ethylene production was announced – translating to $16.5 billion investment in the form of new plants or upgrading the existing plants to utilize abundant natural gas. This presentation shows how steady state and dynamic simulation has been used to improve plant capacity and efficiency for both retrofit of existing facilities and design of the new plants. Two case studies will be presented:
The strategy is to use steady state simulation and optimization tools to establish the heat and material balance for various operating scenarios, set the production and energy targets, and determine the feedstock / operating conditions needed to maximize the profit. Dynamic simulation models were used to verify the design, evaluate alternative control strategies, operator training, and real time optimization application.
There is no registration fee. The lunch menu ranges from $8 to $12, and the South Texas Section will subsidize lunches by $3 per attendee.STS members as well as non-members are welcome to attend. We only request that you pre-register at the STS-AIChE.org website so we can get an accurate head count for the restaurant.
