The document contains a list of typical process equipment used in reforming and catalyst regeneration sections of a refinery, including reactors, columns, vessels, furnaces, heat exchangers, pumps, compressors and blowers. It also provides comparisons of different reforming processes and their key parameters such as RON, reaction pressure, LHSV, H2/HC ratio, yield and cycle length. Finally, it summarizes the assessment of a recommended process/technology for criteria such as performance, reliability, safety, costs and flexibility.

⑸Catalyst Lift
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
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
