467387 A Heuristic-Based Model for Gasification-Based Plants with Flexible Feedstock/Product in Carbon Constrained Scenarios
In this study, the impact of the sulfur, ash, moisture content, and heating value are considered for a wide range of coals and biomass. Heuristics, continuous and discrete design variables and cost functions are used to build various modules for major process units including gasification island, acid gas removal, water gas shift reactor, and application specific processes. A heuristic-based algorithm is used to identify the near-optimum modules (nodes) of gasifier and downstream subsystems to determine the process route with the maximum net present value under various carbon tax schemes for a given set of inputs and constraints.
This model examines a myriad of alternative pathways to determine the most economical match of carbonaceous feedstock composition, gasifier choice, and syngas processing subsystems to a process application of interest including electricity, hydrogen, methanol and Fischer-Tropsch hydrocarbon production.
