P12-10 燃料電池用石炭ガス製造技術開発 (EAGLE) の概要

抄録

The purpose of the EAGLE (coal Energy Application for Gas, Liquid and Electricity) Project is to develop the technology to produce coal gas for fuel cells. The EAGLE system applies an oxygen blown, entrained flow type gasifier, in which the spiral flow is formed. Oxygen is produced with an ASU (Air Separation Unit) and supplied to the gasifier. The produced coal gas is cooled through the radiant section of the gasifier and a syngas cooler. Impurities in raw syngas are removed with water scrubbers, a COS converter and an MDEA (Methyl Di-Ethanol Amine) absorber. Part of the syngas is further desulfurized with iron oxides for fuel cells. The EAGLE Project is subsidized by METI (Ministry of Economy, Trade and Industry) and NEDO (New Energy and Industrial Technology Development Organization). In 1995,a feasibility study of IGFC (Integrated coal Gasification Fuel Cell combined cycle) systems was conducted. In 1996 and 1997,a basic design and a detailed design were carried out, respectively. Its construction work was started at Wakamatsu Operations & General Management Office in August 1998. A pilot plant test has continuing since July 2001.
