Abstract
A stripper and a stripping process
for removing the flue gas carried by regenerated catalyst. A cylindrical
stripper mainly comprises a degassing pipe at the longitudinal
axis, a horizontal pipe connected with the lower end of the degassing
pipe, several sets of inner annular baffles and outer annular
baffles arranged in alternative arrangement along the vertical
direction. Inner annular baffles are fixed on the degassing pipe,
outer annular baffles are fixed on the inner wall of the cylinder.
The degassing pipe has holes below each set of the inner annular
baffles. The regenerated catalyst enters the stripper from the
upper part, comes into a countercurrent and crosscurrent contact
with steam from the annular steam conduit, and the stripped regenerated
catalyst leaves the stripper from the bottom. The removed flue
gas and the excessive steam enter the degassing pipe through the
opening part of the degassing pipe under each set of inner annular
baffles and leave the stripper from the top under the action of
steam or air from the horizontal pipe. Using this stripper can
minimize the amount of the flue gas carried by regenerated catalyst.
