The composition of the stack gas from an oxy‐combustion power plant is about 75 mol % carbon dioxide. The stream must be purified to about 95 mol % by removing light inerts such as nitrogen, oxygen, and argon. The product stream must be compressed to 110 bar for sequestration. This article presents a simple control structure for the double‐flash compression and purification process to achieve these objectives. © 2015 American Institute of Chemical Engineers AIChE J, 61: 1581–1588, 2015
