What is an appropriate ratio of heat exchange area to catalyst loading in a methanol synthesis tower? Typically, the methanol production capacity is correlated with the diameter of the synthesis tower, as well as with the amount of catalyst loaded. Shell-and-tube towers, such as those for 100,000-ton coal-to-methanol processes, have a catalyst loading of 21–27 m3. The catalyst loading for 200,000 tons of coal-to-methanol production is 37–43 m3. The catalyst loading for 500,000 tons of coal-to-methanol production is 60-80 m3. What is an appropriate ratio of heat exchange area to catalyst loading in a methanol synthesis tower?
To ensure the heat transfer rate, the ratio of the heat transfer area to the amount of catalyst loaded in a typical shell-and-tube reactor is around 100:1.
What are Luchita, Casalita, and Davita respectively?
The amount of catalyst loaded is closely related to pressure; higher pressure results in a higher space-time yield. Currently, the pressure for monohydric alcohols in China is 10.0 MPa, and the space-time yield can reach 2.0.
