Continuous catalyst unloading device |
摘要 |
The present invention is for a continuous system wherein spent catalyst is removed from a regeneration vessel, while fresh catalyst is added in order to maintain proper catalyst activity in a hydrocarbon processive system. The withdrawal of the spent catalyst must be achieved at a steady flow rate which is compatible with the introduction of fresh catalyst of the hydrocarbon processing system. This flow rate is controlled by a downstream pressure and venting control in the spent catalyst hopper stage acting in conjunction with a novel flow restriction zone in a discharge conduit.
