How much longer can the methanol catalyst be used? A 200,000-ton methanol plant uses Linde reactors; after catalyst reduction, the temperature entering the reactor is 105°C, the temperature at the inlet of the catalyst bed is 280°C, the peak temperature is 290°C, and the temperature at the outlet is close to 280°C. After 2 years of use, the inlet temperature to the tower was 112°C, the inlet temperature of the catalyst bed was 280°C, the hotspot temperature was 306°C, and the outlet temperature was close to 290°C. How much longer can the methanol catalyst be used?
You are referring to a gas-cooled synthesis tower with a low-pressure waste boiler at the outlet; this design is likely related to the properties of the gas, as well as the design and operation of the synthesis process, and it may last for about two years.
A Linde synthesis tower is used, with a low-pressure waste boiler at the outlet.
It’s about a year; if there are more products, it’s possible they won’t reach grade one.
The key is first to check the technical specifications provided by the catalyst manufacturer to see what the maximum temperature can reach, and second to examine the composition of the current crude methanol; if its composition is not very different from the original one, it should be possible to use it for the entire design lifespan
It should be fine to use it for 3 years.
