One exemplary embodiment can be a separation system. The separation system can include an adsorption zone, a rotary valve, a transition zone, and one or more pipes. Usually, the transition zone includes one or more lines communicating the rotary valve with the adsorption zone. The rotary valve alternatively may distribute an input of a feed or a desorbent to the adsorption zone or alternatively can receive an output of a raffinate or an extract from the adsorption zone in a line, and a remnant may remain in the line from a previous input or output. One or more pipes outside the transition zone communicating with the rotary valve can form at least one pipe volume receiving an input for dislodging a remnant or for receiving a remnant from the line. The remnant may be different from the input or output.
