Issues related to the spares for catalyst tanks in catalytic units
Thread Content
What is the appropriate approach regarding the backup supply in the catalyst tank of a catalytic unit? Should the balance tank be kept empty to be used for removing catalyst in case of problems with the unit, or should it contain a certain amount of catalyst to be used as a supplement in case there are issues with the unit’s regenerator? Which approach is more reasonable? ?
After starting operation, it’s generally not necessary to add a balancing agent; only fresh agents need to be added
A certain amount should be kept on hand, so as to adjust the bed layer parameters
