Principles for raising temperature in the synthesis tower
Thread Content
In a synthesis tower, how can one determine whether it is necessary to raise the temperature and by how much?
One-way conversion rate, methanol production, recycle gas volume, system pressure, etc
Methanol produced from coal features unstable components, unstable system pressure, and an unstable hydrogen-to-carbon ratio. The output is indeed low. Could you explain in detail?
How long has the catalyst been in use?
Imported catalyst, from Johnson Matthey.
A shift of the hot spot to a later position, reduced output, increased specific consumption, greater release of gas, and a decreasing hydrogen-to-carbon ratio are all signs that heating is required.
By combining the one-way conversion rate and the overall conversion rate, it is determined whether the issue lies with the components or with the catalyst activity
Do not let it exceed 35 degrees in 1 hour
The typical service life of a synthetic catalyst is 3 years. The initial temperature is 215 degrees, while it rises to 250 degrees later on. The decision to increase the temperature depends mainly on the methanol production rate and the hydrogen-to-carbon ratio; each increase in temperature should not be too large – it is recommended to raise the temperature by 0.5 degrees at a time.
