Abstract:

The main process areas of integrated gasification combined cycle (IGCC) plants without and with carbon dioxide (CO₂) capture are described. Key factors in IGCC plant design are described for major process areas, including gasification, water–gas shift, gas turbine, CO₂ capture, and other emissions control technologies. The advantages and limitations of coal IGCC plants are discussed. The main development trends of IGCC technologies are reviewed and summarized.
