Utilizing flue gas heat for carbon dioxide capture

A heat integration method, comprising:

• providing a hot gas stream, wherein the hot gas stream comprises carbon dioxide and at least one gas from the following:
• carbon monoxide, nitrogen, and oxygen,
• recovering waste heat from the hot gas stream by producing a steam stream by indirect heat exchange,
• introduce the steam stream into a head absorption chiller, thereby producing a chilled water stream,
• cooling the hot gas stream to less than 100 F, by utilizing at least a portion of the chilled water stream in indirect heat exchange, and by utilizing quench water in direct heat exchange, thereby producing a cooled gas stream,
• introducing the cooled gas stream into a temperature swing adsorption unit, thereby producing a dried gas stream, and.
• introducing the dried gas stream into a cryogenic partial condensation unit, thereby producing a product carbon dioxide stream.
