The IECMThe IECM
• A desktop computer model developed for DOE/NETL
• Provides preliminary design estimates of performance, emissions, costs and uncertainties:
PC, NGCC and IGCC plantsEmission control systemsCO2 capture and storage options (pre- and post-combustion, oxy-combustion, transport, storage)
• Roughly 1000 users worldwide

Project Objectives Project Objectives (1)(1)• For selected power system components, develop
reduced order models that run quickly and efficiently in a variety of widely-used modeling environments (e.g., IECM, Aspen Custom Modeler)
IGCC plants with and without CO2 capture and storage:– Alternative gasifier designs (e.g., GE quench, GE radiant,
Shell, E-Gas, Transport Reactor) – Alternative acid gas removal systems (e.g., amine system,
Selexol, Rectisol)– Alternative gas turbines (e.g., GE Frames 7FA, 7FB, G, H)
• Year 1 focus is on one alternative gasifier; Years 2 and 3 will focus on additional plant components
Project Objectives Project Objectives (2)(2)
• Incorporate and link economic cost models in Aspen-based performance models of advanced gasification-based power systems
Equation-based models for capital cost, operating and maintenance (O&M) cost, and total cost of electricityUtilize current IECM cost modelsEPRI TAG methodology Implement in Aspen Plus as a User Block
• Year 1 focus is on GE Quench gasifier IGCC system
