System and method of cooling

摘要

A hot fluid stream is cooled by air in a first stage or device 110 to a first temperature. The thus cooled fluid stream is further cooled by water to a second temperature in a second stage or device 120 in series with the first stage or device 110. The hot fluid stream flows from equipment, for example, a compression stage in an air separation plant or is itself a heat exchange fluid which has been warmed by indirect heat exchange with hot gas flowing from such a compression stage.
