There are a large number of catalyst particles in the backflushing of the catalyst dust collector in the continuous reforming unit
Thread Content
The continuous reforming unit has just started operation, and catalyst dust is removed on a daily basis; there are many intact particles. Is this due to an excessive amount of gas used for leaching, or is it because the catalyst circulation is irregular during operation, with varying amounts of catalyst being used at different times, and the catalyst has not yet burned out? How should one operate the catalyst circulation DCS? Could someone with experience give some guidance?
To ensure thorough dust separation and smooth catalyst circulation, it is inevitable that some crushed particles, or even intact particles, will be carried along.
It’s better to waste a few whole particles than to let a large amount of fine powder enter the subsequent system and clog the Johnson screen
Check whether the differential pressure is stable. At the beginning of operation of the unit, the amount of washing gas is quite high; determine what proportion of the particles are in their whole form When it gets larger, it can be adjusted lower appropriately. As long as the dust can be washed out, that’s fine.
