APPARATUS FOR GASIFICATION WITH SUPERCRITICAL FLUID

摘要

[Problem] In a gasification apparatus that heats and pressurizes a gasification feed to obtain a fluid in a supercritical state and subjects the gasification feed to a degradation process to obtain a fuel gas, to effectively utilize energy of the processed fluid while suppressing generation of tar. [Solution] A gasification apparatus that heats and pressurizes a gasification feed to turn the same into a supercritical state and subjects the gasification feed to a degradation process to obtain a fuel gas, the apparatus including: a heat exchanger (31) that introduces the gasification feed into a low temperature side flow channel (31a) and introduces the processed fluid in a supercritical state into a high temperature side flow channel (31b) so as to conduct heat exchange between the gasification feed and the processed fluid; a gas-liquid separator (51) that retrieves from the high temperature side flow channel (31b) the processed fluid which is in a subcritical state due to the heat exchange to separate gas and liquid and returns the separated liquid into the high temperature side flow channel; and a turbine (61) powered by the fuel gas separated by the gas-liquid separator.
