This report documents cost models developed for selected integrated gasification combined cycle (IGCC) systems. The objective is to obtain a series of capital and operating cost models that can be integrated with an existing set of IGCC process performance models developed at the US Department of Energy Morgantown Energy Technology Center. These models are implemented in ASPEN, a Fortran-based process simulator. Under a separate task, a probabilistic modeling capability has been added to the ASPEN simulator, facilitating analysis of uncertainties in new process performance and cost (Diwekar and Rubin, 1989). One application of the cost models presented here is to explicitly characterize uncertainties in capital and annual costs, supplanting the traditional approach of incorporating uncertainty via a contingency factor. The IGCC systems selected by DOE/METC for cost model development include the following: KRW gasifier with cold gas cleanup; KRW gasifier with hot gas cleanup; and Lurgi gasifier with hot gas cleanup. For each technology, the cost model includes both capital and annual costs. The capital cost models estimate the costs of each major plant section as a function of key performance and design parameters. A standard cost method based on the Electric Power Research Institute (EPRI) Technical Assessment Guide (1986) was adopted. The annual cost models are based on operating and maintenance labor requirements, maintenance material requirements, the costs of utilities and reagent consumption, and credits from byproduct sales. Uncertainties in cost parameters are identified for both capital and operating cost models. Appendices contain cost models for the above three IGCC systems, a number of operating trains subroutines, range checking subroutines, and financial subroutines.
