What are the consequences of too fast a punching rate in a methanol synthesis tower, and what are the consequences of too slow a rate?
If the stamping speed is too high, the pressure difference across the catalyst increases, resulting in greater forces acting on the catalyst, which can cause it to become powdered and thus affect its lifespan.
An excessively high punching rate in the methanol synthesis tower exerts heavy stress on the catalyst in the bed, causing it to break down and increasing the pressure difference in the synthesis tower. If it’s just pressurization, it’s fine to do it slowly; but when raising the pressure of syngas, it’s necessary to control the temperature carefully, as it shouldn’t rise too quickly. Slow heat removal from the reaction also has an impact on the catalyst.
Too fast a rate has a significant impact on the catalyst, leading to powder formation and consequently excessive resistance in the synthesis tower. Being too slow will prolong driving time and result in unnecessary waste.
Stamping must maintain a certain stamping speed! It is generally around 0.15 MPa; otherwise, it’s like what was mentioned in the previous comments.
Too high a rate can cause the catalyst to become fragmented; it is best to keep the stamping rate at 0.1 Mpa/min
