How to clean the ash accumulation of the protective agent in the conversion purification furnace?
Thread Content
Our plant uses isothermal shift reactors for the shift process; there are purification reactors in front of these shift reactors (one in operation and one as backup). At the upper part of the purification reactors lies a protective agent, while at the lower part there is both a protective agent and some catalyst. Currently, the pressure difference in purification reactor A has increased, so it has been switched to reactor B. I now think that the high pressure difference in Furnace A is caused by ash accumulation on the upper layer of the protective agent; I plan to start the furnace to clean it. I was wondering if anyone else has encountered this issue of ash accumulation on the protective agent and how they dealt with it?
After the cooling and replacement process is complete, depending on the situation, dust accumulation can be removed using a vacuum, while lumps need to be broken up with a hammer before being removed manually. Be careful to prevent fires, explosions, and poisoning
Dust accumulation on the gas belt? What gasification technology is used? Poor washing efficiency of the carbon scrubber?
Just replace the protective agent directly; the cleaning effect is poor. Are you using a space furnace for gasification?
