METHODS AND APPARATUSES FOR PROVIDING PROCESS CONTROL IN DUAL COLUMN PROCESSES

摘要

Methods and apparatuses for providing process control in dual column processes are provided. In an embodiment, a method for processing a raffinate stream includes forming the raffinate stream in an adsorbent zone. The method monitors the pressure in the adsorbent zone. The raffinate stream is split into a first portion and a second portion. A first flow rate of the first portion is adjusted in response to the pressure in the adsorbent zone, and a second flow rate of the second portion is adjusted in response to the first flow rate. The first portion is fractionated in a first column and the second portion is fractionated in a second column.
