Do anyone have any good methods for removing the catalyst from a tubular fixed-bed reactor? Right now we are removing it one tube at a time manually, which is extremely time-consuming and labor-intensive
There are several methods for removing catalyst from a tubular fixed-bed reactor: 1. Pneumatic conveying method: The catalyst to be removed is blown out of the reactor through a pneumatic conveying system. 2. Vibration method: A vibration device is used to shake the reactor, thereby loosening the catalyst so that it can be removed. 3. Mechanical extraction method: Using specialized catalyst removal machinery to extract the catalyst. 4. Active gas method: High-temperature active gases such as nitrogen and hydrogen are injected into the reactor to decompose and remove the catalyst. Among the methods mentioned above, pneumatic conveying and shaking are the more commonly used approaches; they allow for rapid catalyst removal without damaging the reactor or the catalyst. However, the specific method to choose depends on the actual circumstances. .
This is how it’s uninstalled; there’s no better way
Right now we’re using the first method: 20 people take turns working each time, dealing with 2,800 tubes, which takes 2–3 days. It leaves the employees dirty and exhausted. We want to improve this, but there’s no good solution
