Problems solved by technology

[0004] In view of this, the present invention provides a feeding control method and device for hydrogasification technology, which is used to solve the problem of large scale, complex reactions, and high requirements for working conditions in the entire hydrogasification system in the prior art. Mistakes in the process will bring huge economic losses and safety risks. Due to the different reaction mechanism and furnace structure of other pulverized coal-to-synthesis gas technologies, the feeding control method cannot be used in hydrogasification technology. Therefore, there is currently no The problem of perfect feeding control method

Abstract

The invention discloses a feeding control method for a hydrogasification technology. The feeding control method comprises the following steps: establishing a feeding environment; performing system pressure rise on a hydrogasification system under the situation that the feeding environment meets preset environmental requirements; performing system temperature rise on the hydrogasification system under the situation that the system pressure of the hydrogasification system meets preset pressure requirements; and feeding the hydrogasification system under the situation that the system temperatureof the hydrogasification system meets preset temperature requirements. The feeding control method disclosed by the invention has the benefits that the stable hydrogasification production conditions are finally realized by feeding environment establishment, system pressure rise, system temperature rise and feeding control, so that the problem of safe start-up of an industrial hydrogasification device can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a feeding control method and device for hydrogasification technology. Background technique [0002] Coal hydrogasification technology is to carry out coal hydrogasification reaction under pressure and certain temperature conditions to produce crude gas, aromatic oil products and semi-coke products with methane, carbon monoxide and hydrogen as active components. The methane content is as high as 80% (dry basis volume) after the hydrogen is separated from the coal gas exiting the gasifier, which is an advanced technology for coal-to-methane production. [0003] The hydrogasification technology is in the process of industrialization, and the feeding control method is one of the most critical technical bottlenecks. Due to the large scale, complex reaction, and high working conditions of the entire hydrogasification system, if errors occur during the start-up and feeding ...
