Abstract
HYCOL, an advanced coal gasification pilot plant located in Sodegaura, Chiba, Japan, successfully completed its three-year operation program on April 15, 1994. This unit, sponsored by New Energy and Industrial Technology Development Organization (NEDO),as a part of the governmental new energy program called the Sun Shine Project, operated by Research Association for Hydrogen-from-Coal Process Development (HYCOL), was based on an entrained-flow, oxygen-blown, one gasification chamber with two-step spiral flow multi-burners. HYCOL pilot plant was designed to gasify 50 T/D of coal. The objectives of the program were to obtain process design data, confirm scale-up rules, examine equipment life, and gasify a variety of coals for the next demonstration R and D. During the program, 4 different coals were gasified. The plant logged 2164 hours of operation, including a 1,149 hour long and uninterrupted run on Taiheiyo coal. Characterization of mass and heat balance, and turnaround inspections validated superior features of the process. This paper describes the overall performance of HYCOL during the three-year test program.
