IGCC Plant (Kanagawa)

Featured Project

Kanagawa/Japan

The residual oil left over in the refining of petroleum contains a large amount of high viscosity, high sulfur content oil, and the efficient utilization of this material has been an issue for the petroleum refining industry for many years. JGC was quick to react to the trend in the petroleum industry toward the efficient utilization of residual oil, focused on integrated gasification combined-cycle (IGCC) power generation technology as the best solution, and has been gathering IGCC technology and knowledge for over 10 years.

At the end of 1997, taking into account JGC’s technological expertise in the field of IGCC facilities and its wealth of experience in petroleum refining and power generation plant projects, the Nippon Oil Corporation Group selected JGC as the main contractor for a 430,000KW IGCC power generation project. JGC was responsible for the engineering, procurement, construction, and commissioning of the main facilities. Previous IGCC projects had involved separate contracts covering the construction and subsequent management of each facility. In a world first, JGC has had overall responsibility for the management of all facets of an IGCC project.

In IGCC facilities, it is necessary to integrate facilities performing heterogeneous functions: the gasification facilities that turn residual oil into usable fuel, and the combined cycle facilities that generate electricity. Drawing on our technology and project management abilities, JGC executed the project by optimizing the engineering of the facilities for each process. In addition, this project was the first in the world in which the gasification process was controlled in tandem with the power demand, using high-level controller technology to increase and decrease the amount of power generated.
