Process and apparatus for optimization of integrated air separation systems. In an integrated process for the compression, cooling, and purification of air, an adiabatic compressor compresses an air stream to produce a compressed air stream. The compressed air stream is used to warm a first pressurized stream at a first pressure and a second pressurized stream at a second pressure. The produced streams include a first warmed pressurized stream, a second warmed pressurized stream, and a cooled compressed air stream. The first warmed pressurized stream is gaseous and is expanded in a turbine. At least part of the work produced by the turbine is used to power the adiabatic compressor. The cooled compressed air stream is further cooled by a cooling unit by heat exchange with water, and then purified in a purifying unit using a TSA process. At least part of the warmed second pressurized stream is used in cooling the water to be used in the cooling process and/or in warming the gas used to regenerate purifying unit.
