Project GoalProject Goal

• Utilize existing strengths of current NETL in-house Aspen-based modeling efforts, and the NETL-supported IECM modeling project at Carnegie Mellon, to advance the capabilities and compatibility of both modeling efforts to serve a spectrum of model users and applications

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

The Collaboratory ProjectThe Collaboratory Project

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
