Briefly describe the types and basic structure of methanol synthesis towers?

The main types of low-pressure methanol synthesis towers are as follows: (1) shell-and-tube methanol synthesis tower, (2) multi-stage quench methanol synthesis tower, (3) multi-stage radial methanol synthesis tower, (4) adiabatic methanol synthesis tower, (5) Casale axial-radial mixed-flow synthesis tower; foreign technologies； Danish company Topsoe, German companies Lurgi and Linde, and Swiss company Casale can be basically divided into two main categories: multi-stage adiabatic type and cold-tube type. And cold-tube types can be further divided into air-cooled and water-cooled types ；

And cold-tube types can be further divided into air-cooled and water-cooled types ； Currently, domestic low-pressure methanol synthesis technology is on par with foreign technologies, and large-scale plants are under construction. It should be noted that the intrinsic safety of the internal components of the synthesis tower is what requires the most careful consideration. ““Water cooling – catalyst outside the tube – radial flow” is the development direction.
