Abstract
Embodiments of the present invention provide, for an adsorption separation system for separating normal paraffins from a hydrocarbon feed stream, a process for switching the adsorption separation from a triple split desorbent system to a dual split desorbent system, and vice versa. Switching occurs by separating and/or introducing a second flush material in the adsorption separation system. This switching can occur during normal operations.
