Lift Method L-Valve Manifold Lifter Lift Gas: Catalyst for Regeneration N2 N2

Regenerant H2 H2

⑹Locked Hopper Location Below the Regenerator Above the Regenerator

Oper. Stream H2 N2

Function Locked hopper, which is controlled via lock hopper controller, is served to

transfer regenerated catalyst into regenerant lifter in batch-wise based on the recycle volume required, and

pressure balance is served to control catalyst flowing, no valves are

required.

Locked hopper is served to transfer catalyst into the

regenerator, where both the top and bottom special-purpose valves

are controlled based on the setpoints of timer, and thus recycle volume of catalyst for regeneration

is controlled. ⑺Catalyst Reduction
