Embodiment Construction

[0048] For gasification in the gasification reactor (1-21), solid or fluid carbonaceous fuel (1-20) is delivered to the figure 1 In the IGCC power station (Integrated Gasification Combined Cycle-integrated coal gasification combined cycle) shown in. Synthesis gas rich in carbon monoxide and hydrogen is produced in the gasification reactor. This synthesis gas is sent to the chill section. In this quenching section, the synthesis gas is cooled in a known manner, preferably by injecting excess process water (1-29). After water quenching, the synthesis gas is fed to a wet dedusting plant as well as a brine and caustic scrubbing plant (Venturi). The dust-free gas (1-22) saturated with water vapor is then fed to the CO converter (1-23). The water used for chilling in the chilling section carries gasification residues, such as ash, and is conveyed to a waste water treatment plant (1-27). The converted synthesis gas (2-1, 3-1) is cooled in a raw gas cooling unit (1-24) to a temper...

Abstract

The present invention relates to directly cooling coarse coal gas for gasification of an airflow bed. According to the invention, a IGCC (Integrated Gasification Combined Cycle ) plant will propose that a cooler / a saturator cycle is arranged in a coal gas purifier (washing by carbinol at a low temperature), thereby, the heat of water vapour bound in the coal gas may be guided around the coal gas purifier optimum, and the condensation loss of the present scheme is minimized. Furthermore, it is possible to reduce pressure loss in coal gas synthesis path by directly cooling or vaporizing, and theefficiency of the IGCC plant is maximized. .

Description

technical field [0001] The invention relates to a method for processing crude gas in IGCC (Integrated Gasification Combined Cycle) equipment. Background technique [0002] If the raw gas formed during the gasification process is further treated in a raw gas shift after wet dedusting and brine and caustic cleaning and followed by gas cleaning, the raw gas coming out of the gas shift must be cooled and Dissipate the corresponding heat. [0003] The available temperature levels are determined by the partial pressure of water vapor in the raw gas. Especially when using IGCC (Integrated Gasification Combined Cycle-Integrated Gasification Combined Cycle), in terms of efficiency optimization, efforts should be made to effectively return the output heat to other equipment components, and efforts should be made to minimize the pressure loss on the gas side change. [0004] For the use of CO with CO 2 For the IGCC of a separation unit, the process water temperature used for full q...
