Study of Heavy Oil Gasification for IGCC

Ishikawajima- Harima Heavy Industries Co., Ltd. (IHI) have been developing the Gasification and the Hot Gas Cleanup technology for Integrated Gasification Combined Cycle (IGCC). Gasification tests have been carried out in corporation of Tokyo Electric Power Company and Kansai Electric Power Co., Inc., with a 6 ton (coal)/day Texaco process gasification pilot plant (CGT project), which is located at IHI's Aioi Works in Hyogo Prefecture. This project had started in 1986 gasifying various kind of coal, and by the end of November 1996, 15 kinds of coal are gasified and cumulative operation time of 7 000 hours have been achieved. From 1994 in order to diversify availability of fuels for gasification, several kinds of heavy oil had been gasified in this plant. Through these tests the relationship between process variables and the performances of heavy oil gasification became clear. This paper describes the process of the heavy oil gasification and the results of the heavy oil gasification tests which were carried out at the CGT project.
