Abstract

The invention provides a ammonia and methanol synthesizing system which relates to the technical field of ammonia / methanol synthesizing. The system solves the problems of low heat utilization rate and large steam consumption found in the synthesizing process of ammonia and methanol. The ammonia and methanol synthesizing system comprises in sequence: the oxygen generation system, gasification system, transforming system, desulfurization system, decarburization system and synthesis system; the oxygen generation system applies the cryogenic air separation equipment or pressure swing adsorption oxygen making equipment; the gasification system consists of gasification reactor of continuous gasification process of 0.1Mpa to 1.5Mpa. The gasification reactor is either the half jacket structure or whole jacket structure. The cavity of the gasification reactor is connected to the gasification reactor. The ammonia and methanol synthesizing system is used for continuous pressuring and gasification to synthesize the ammonia (or methanol). The heat utilization rate is high and intake of exterior steam is low. The power consumption is also small.

Description

technical field [0001] The invention relates to the technical field of synthetic ammonia / methanol technology, in particular to a synthetic ammonia or methanol system. Background technique [0002] At present, the process flow of the existing ammonia synthesis system and the methanol production system is basically the same. The synthesis process is usually: gasification→coarse desulfurization→compressor→transformation→fine desulfurization→compressor→decarbonization→compressor→synthesis→ Final product. Among them, the gasification reaction is carried out through the gasification reaction furnace in the gasification device. The gasification agent participating in the gasification reaction in the gasification reaction furnace includes water vapor, so it is necessary to pass through the gasification reaction furnace during the gasification reaction. A large amount of water vapor is injected, and the consumption of water vapor is relatively large. In addition, the temperature of...
