Abstract
This work addresses the techno-economic and environmental analysis of an Integrated Gasification Combined Cycle power plant (IGCC) of 308 MWe of gross power, giving particular attention to co-gasification and co-production of electricity and H2. Products, sub-products and effluents distributions are estimated by means of an ad-hoc developed superstructure for conceptual design of syngas generation and treatment, delivering preliminary fiowsheets targeted to co-production. The resulting multi-objective optimization problem evaluates the trade-off between the cost of energy (COE), the total energy efficiency of the plant and the environmental impact evaluated through Impact 2002+ indicator. Sixteen scenarios are considered: 4 different feedstock's combined with 4 alteruative plant topologies; electricity generation from syngas, electricity generation from H2, and purified H2 production from fiue gas in a Pressure
Swing Adsorption (PSA) unit in the Combined Cycle (CC). The case studies environmental boundary has been drawn from cradle to gateo The Pareto Frontiers (PF) for the Key Performance Indicators (KPIs) trade-off evaluation reveals that the scenario
with petcoke as feedstock and H2 production with PSA fiue gas profit is the best one in
terms of eHíciency maximization and COE minimization. Scenario with residual biomass without PSA fiue gas profit is the best in terms of environmental impact.
