A method for liquefying ammonia can include the steps of: providing a pressurized carbon dioxide stream from a power generating facility; expanding the pressurized carbon dioxide stream to a lower pressure that is sufficient to produce a dual phase carbon dioxide fluid; introducing the dual phase carbon dioxide fluid to a gas-liquid separator; withdrawing a liquid stream from the gas-liquid separator; and liquefying an ammonia gas stream in an ammonia liquefier by indirect contact with the liquid stream from the gas-liquid separator, thereby forming a liquid ammonia stream and a gaseous carbon dioxide stream.

A method of temperature balancing for thermal integration of an air separation unit (ASU) with an oxycombustion power generation system, including compressing air through a plurality of compression stages, and routing a first stage compressed air stream through a first heat exchanger in heat exchange communication with a subsequent stage compressed air stream to lower the first stage compressed air stream temperature and increase the temperature of a subsequent stage compressed air stream.
