Optimization of Chemical Processes (cont.) ➢
Optimal operating conditions can be implemented via increased automation at the process, plant, and company levels (eg, Model Predictive Control)
➢
➢
To apply optimization effectively in the chemical industries, both the theory and practice of optimization must be understood.
➢
We will introduce the necessary tools for problem solving. We will focus on those techniques and discuss softwares (MATLAB and/or GAMS ) that offer the most potential for success and gives reliable results.
➢
We will also emphasize one important application area: the Process Integration. Therein both insight-based pinch analysis and model-based math approach will be introduced.
As the power of computers has increased, the size and complexity of problems that can be solved by optimization techniques have correspondingly expanded.
