Abstract: A process for separating a carbon dioxide product stream from a flue gas stream is disclosed. The process comprises passing a stream of carbon dioxide and oxygen to a regenerator to generate a catalyst stream and produce a flue gas stream comprising carbon oxides, and/or nitrogen oxides, catalyst fines, oxygen, and water. Heat is transferred to a water stream from the flue gas stream in a heat recovery unit to form a cooled flue gas stream and a steam stream. Water is removed from the cooled flue gas stream in a dehydration unit to provide a dehydrated flue gas stream. The dehydrated flue gas stream is separated into an oxygen stream and a carbon dioxide product stream.
