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.

An integrated cooling apparatus comprising:
- a) a source of compressed gas;
- b) 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;
- c) a first heat exchanger for warming a stream of water having a second purity, wherein the second purity is lower than the first purity, by indirect heat exchange with a stream of water having the first purity;
- and
- d) a conduit for sending cooled water having the first purity to the cooling unit.
A cooling process comprising:
- a) cooling a compressed gas to form cooled compressed gas by heat exchange with water having a first purity;
- b) warming a stream of water having a second purity, wherein the second purity is lower than the first purity, by indirect heat exchange in a first heat exchanger with a stream of water having the first purity to produce cooled water having the first purity;
- and
- c) sending at least part of the cooled water having the first purity to the cooling unit.
