Recycling flush streams in adsorption separation process for energy savings

摘要

A process to reduce flush circulation rates in an adsorption separation system is presented. The flush stream is used to improve the capacity of the simulated moving bed system by flushing the contents of the transfer lines containing raffinate material back into the adsorbent column. The flush stream is a material that is used to flush the head chambers in the column, or from the rotary valve flush dome sealant.
