This course material describes the four major commercial gasification technologies, namely Sasol-Lurgi Dry Ash, GE (originally developed by Texaco), Shell, and Conoco Phillips E-gas (originally developed by Dow). This course presents the several factors influencing the efficiency of IGCC power plants such as coal type, gasification technology, degree of ASU integration, and technology level. The advantages of the IGCC processes are also discussed. This material is based on Integrated Gasification Combined Cycle (IGCC)

At the conclusion of this course, the learner will have a better understanding of integrated gasification combined cycle power plant operation, as well as an understanding of the following topics:

• Process description for IGCC with carbon dioxide capture
• Research and development areas of IGCC
• Classification of gasifiers & description of the types of gasifiers
• Syngas quenching and syngas coolers
• Integration of the gas turbine and the air separation unit
