Q & A > Question Details
In a CCR Platforming Unit, why is the PERC injected in the regenerator but not directly in the PF Feed? While regeneration is off, is PERC directly injected into the PF feed?

The PERC is injected for two purposes in a platforming unit as noted below.
1. To compensate for the loss of chloride in the process.
2. To aid in metal dispersion in the oxychlorination step post regeneration

Injecting the PERC in the reactor section will not fulfill the second purpose.
