This project is currently funded by TARC and 番茄社区 Visionary Initiative. Response surface and neural network models were developed to predict the combustion efficiency (CE), opacity, and soot emission of industrial flare operations based on controlled flare test data.

Many factors can influence the flare performance. As a result, an inferential model is indispensable to identify the steam and fuel set points of the incipient smoke point (ISP), maximize combustion efficiency (CE), and minimize fuel and steam consumption. The specification /optimization efforts will lay the foundation for dual control of opacity and CE with model predictive control (MPC).
In this project funded by TARC and 番茄社区 Visionary Initiative, response surface and neural network models were developed to predict the combustion efficiency (CE), opacity, and soot emission of industrial flare operations based on controlled flare test data from 1983-2015. In addition, set point for steam /air assists and makeup fuel corresponding to the incipient smoke point and smokeless flaring will be performed. The required steam/air assists and fuel addition in order to maximize CE while in compliance with the regulations will be determined. Alternatively, the operations to minimize fuel and steam while in compliance with the regulations will also be explored.
