IGCC-based poly-generation system

Abstract

The invention discloses an IGCC-based poly-generation system. The oxygen outlet of an air separation system is divided into two paths, one path is communicated with the inlet of a gasification furnace, the other path is communicated with an oxygen output pipeline, the argon outlet of the air separation system is communicated with an argon output pipeline, and the nitrogen outlet of the air separation system is communicated with the inlet of a synthetic ammonia system; a carbon-containing fuel pipeline is communicated with the inlet of the gasification furnace, the synthesis gas outlet of the gasification furnace is communicated with the heat release side inlet of a heat exchanger, the heat release side outlet of the heat exchanger is communicated with the inlet of a conversion system and the inlet of a productization system, and the outlet of the conversion system is communicated with the inlet of a hydrogen and carbon dioxide separation system; and the hydrogen outlet of the hydrogen and carbon dioxide separation system is communicated with the inlet of the productization system and the inlet of a synthesis ammonia system. The poly-generation system can realize diversification of IGCC system products, and the economical efficiency of the IGCC system is greatly improved.

Description

technical field [0001] The invention relates to a polygeneration system, in particular to an IGCC-based polygeneration system. Background technique [0002] The integrated gasification combined cycle power generation system (IGCC) is mainly used for power generation. There will be a mismatch between the gasification island and the power island. Due to the influence of the national grid dispatch, the IGCC cannot operate at full capacity, basically only half of the time in a year In operation, the power island is in a shutdown state at this time, and the gasification island is also forced to stop. The economic benefit is poor, which seriously affects the promotion and application of IGCC. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an IGCC-based polygeneration system, which can make full use of the gasification island of the IGCC to produce a variety of products and great...
