ABSTRACT:
An integrated cooling apparatus and process which includes a source of compressed gas; a cooling unit for cooling the compressed gas to form cooled compressed gas by heat exchange with water having a first purity, thereby producing a stream of cooled compressed gas and a stream of warmed water having the first purity; a first heat exchanger for warming a stream of water having a second purity, the second purity being lower than the first purity, by indirect heat exchange with a stream of water having the first purity; and a conduit for sending cooled water having the first purity to the cooling unit.
