Short Name: Catalyst Recovery
Description: The Catalyst is recovered via Centrifugation, Filtration, or Settling., and the recovered Catalyst is sent back to the Reactor. Small amounts of the Catalyst may be lost as fines in the crude Product Stream or intentionally discarded as a portion of the recovered Catalyst Stream. The crude TDA then goes through a series of Distillation Columns, the first one being the Solvent Recovery Column.
