Study on Commericialization of High Efficiency IGCC System

Abstract

The Integrated Gasification Combined Cycle(IGCC) is regarded as a prospective winner of thermal power system in the next decade. Ishikawajima-Harima Heavy Industries CO., Ltd.(IHI) has been developing gasification technology and dry gas desulfurization technology. These are key technologies for IGCC commercialization. IHI has constructed Texaco Type coal gasification test facility and has been carrying out various tests since 1987. Also at the Japanese national IGCC development project, IHI has been in charge of a dry gas desulfurization pilot plant development for 200 coal tons / day gasification plant. This worldly largest desulfurization unit has performed successfully and concluded in February 1996. With these test results, IHI has continued to improve IGCC system through various feasibility studies with Toshiba who designed the combined cycle. We also carried out parameter survey that focused on the influence of fuel properties. These results made clear some useful features for IGCC development.
