IFP Fixed-bed Semi-regenerative Unit Revamps, Troubleshooting
IFP (CCR) Technology Optimization

In trying to determine the potential benefits from revamping a Fixed-bed Semi-Regenerative catalytic reformer, a refiner must evaluate several areas of operation:

— What is the unit operating objective?
— What degrees of freedom are available for revamp /optimization?
— Can refinery margins, and the discretionary capital budgeting program support the revamp / optimization?

Refiners must select the catalytic reformer operating point that will maximize profit within the following:

1) the mechanical constraints of the unit and
2) the short term unit operating objectives.

projects that improve operating profit are compared with the required capital investment.

This is done using discounted cash flow, or one of a number of other capital budgeting analysis tools, and those projects with the greatest return are put at the top of the capital budget list.

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 Location At the top of Reactor 1# Above Reactor 1# Reduction Method Two-stage reduction One-stage reduction Purity Requirements for Reduction H2 Reformer H2 can be used 99mol% H2 required ⑻Dust Elutriation Oper.
