Technical Field
[0001] This utility model relates to the field of methanol production technology, specifically to a conversion furnace device for producing methanol from natural gas. Background Technology
[0002] Methanol (CH3OH) is an important chemical raw material, widely used in the production of formaldehyde, acetic acid, MTBE (methyl tert-butyl ether), dimethyl ether, and other chemicals. It is also used as a fuel and solvent. Industrially, methanol is mainly synthesized by reacting carbon monoxide (CO) and carbon dioxide (CO2) with hydrogen (H2) in the presence of a catalyst.
[0003] Based on the above, the inventors have discovered the following problems: the current converter structure usually has the tube bundles used for the reaction arranged around the burner, and the hot gas generated by the burner flows vertically upward to the flue gas outlet. A large amount of heat cannot be directly used to heat the tube bundles, resulting in a large amount of energy waste and inconvenience in use.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a conversion furnace device for methanol production from natural gas, in order to achieve a more practical purpose. Utility Model Content
