Embodiment Construction

[0038] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

A methanol synthesis reaction system comprises an air-cooling reactor, a first water-cooling reactor and a second water-cooling reactor. The air-cooling reactor comprises an air-cooling system and a first air collecting pipe. The air-cooling system comprises an air inlet pipe and a second air collecting pipe. The air-cooling reactor comprises a first air port, the first water-cooling reactor and the second water-cooling reactor and are each provided with a second air port and a third air port. The air inlet pipe, the second air collecting pipe, the second air port of the first water-cooling reactor, the third air port of the first water-cooling rector, the second air port of the second water-cooling reactor, the third air port of the second water-cooling reactor, the first air port and the first air collecting pipe are sequentially connected so that the gas can sequentially react in the first water-cooling reactor, the second water-cooling reactor and the air-cooling reactor. By mans of the methanol synthesis reaction system, a high alcohol net value can be obtained. Besides, the recycle ratio is reduced, the compression power consumption of circulating gas is greatly reduced, and accordingly low-resistant high-alcohol-net-value methanol large-scale production is achieved. The invention further discloses a methanol synthesis reaction method.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a methanol synthesis reaction system and a methanol synthesis reaction method applied in methanol synthesis production. Background technique [0002] The methanol synthesis reaction is a strongly exothermic reversible reaction, the main reaction formula [0003] CO+2H 2 =CH 3 OH+ΔH R1 [0004] CO 2 +3H 2 =CH 3 OH+H 2 O+ΔH R2 [0005] ΔH R1 =-76519.5-49.2909T----------P132 [0006] ΔH R2 =-37858.2-22.666T-------P132 [0007] The reaction is carried out in a reactor equipped with a catalyst. The modern methanol catalyst is a low-pressure low-temperature copper-zinc-aluminum system with a pressure of 4.0MPa-8.5MPa and a temperature of 210°C-280°C. It can be seen from the above that the unreacted gas must be preheated to 210°C. During the reaction process, the heat release is large and the temperature rises greatly. For example, the temperature rises by 32°C f...
