Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of inorganic sulfur and organic sulfur in the mixed gas, the mixed gas is usually directly passed into the fine stripping tower for desulfurization, but the use of the fine stripping tower is to decompose and desulfurize the organic sulfur, not only for The desulfurization effect of inorganic sulfur is poor, and the existence of inorganic sulfur can easily affect the problem of decomposition and removal of organic sulfur.

Embodiment 1

[0032] Such as Figure 1 to Figure 7 As shown, in the methanol production method described in the present invention, the steps of the methanol production method are as follows: S1: raw material preparation: firstly, coke oven gas and coal-based synthesis gas are mixed to form a mixed gas; S2: raw material purification: Pass the mixed gas into the filter to filter out impurities such as oil and dust carried by the mixed gas, and then compress the mixed gas through the first heat exchanger for heat exchange and temperature increase; S3: desulfurization and decarbonization process: pass the mixed gas through the first heat exchanger In a desulfurization box 1, the inorganic sulfur in the mixed gas is removed through the desulfurizing agent in the first desulfurizing box 1, and then the cross plate 17 is driven by the motor 15 to keep the desulfurizing agent in a flowing state, increasing the time of the mixed gas in the desulfurizing agent , to improve the desulfurization efficie...

Embodiment 2

[0042] Such as Figure 8 As shown in Comparative Example 1, as another embodiment of the present invention, a layer of rubber layer 35 is attached to the top of the first arc-shaped block 28; during operation, in order to prevent the first arc-shaped block 28 and the activated carbon adsorption layer from A large collision noise occurs between 13, and a layer of rubber layer 35 is fixed on the first arc-shaped block 28, which can effectively reduce the generation of noise through the buffer of rubber layer 35, and will not cause damage to the activated carbon adsorption layer 13 .

[0043]Working principle: The mixed gas entering from the air guide pipe 11 will pass into the spiral pipe 2 and then be sprayed out through the air outlet pipe 21. Since the spiral pipe 2 occupies the entire bottom of the first desulfurization tank 1, the mixed gas introduced through the spiral pipe 2 can be evenly distributed. is distributed in the desulfurizing agent liquid, introduced into the ...

Abstract

The invention belongs to the technical field of methanol production, specifically a methanol production method and its production equipment. The steps of the methanol production method are as follows: S1: raw material preparation: firstly, coke oven gas and coal-based synthesis gas are mixed to form Mixed gas; S2: raw material purification: pass the mixed gas into the filter to filter out impurities such as oil and dust carried by the mixed gas, and then compress the mixed gas through the first heat exchanger for heat exchange and temperature increase; the invention provides a A methanol production method and its production equipment to solve the problem of inorganic sulfur and organic sulfur in the mixed gas. Generally, the mixed gas is directly passed into the fine stripping tower for desulfurization, but the fine stripping tower is used to decompose and desulfurize the organic sulfur. Not only is the desulfurization effect on inorganic sulfur poor, but the presence of inorganic sulfur also easily affects the decomposition and removal of organic sulfur.

Description

technical field [0001] The invention belongs to the technical field of methanol production, in particular to a methanol production method and production equipment thereof. Background technique [0002] Methanol is an organic compound composed of methyl and hydroxyl groups. It has the chemical properties of alcohol. It has a wide range of uses and is mainly used to manufacture formaldehyde, acetic acid, methyl chloride, methylamine and dimethyl sulfate. Products can also be mixed with gasoline for use as an alternative fuel. [0003] There are also some technical solutions on methanol production technology in the prior art. For example, a Chinese patent with application number 2015103879937 discloses a method for producing methanol, which involves mixing coke oven gas and coal-based synthesis gas to form a mixed gas, wherein A part of the methane reforming is compressed together with the rest of the mixed gas and then purified to remove impurities such as H2S. The removed hy...
