ABSTRACT
ABST R AC T Integrated Gasication Combined Cycle (IGCC) system using coal gasication is an important approach for future energy options. This work focuses on understading the system operation and optimizing it in the presence of uncertain operating conditions using ASPEN Plus and CAPEOPEN compliant stochastic simulation and multiobjective optimization capabilities developed by Vishwamitra Research Institute. The feasible operating surface for the IGCC system is generated and deterministic multiobjective optimization is performed. Since the feasible operating space is highly nonconvex, heuristics based techniques that do not require gradient information are used to generate the Pareto surface. Accurate CFD models are simultaneously developed for the gasier and chemical looping combustion system to characterize and quantify the process uncertainty in the ASPEN model.
