Abstract

In a pumped liquid oxygen (LOX) air separation unit (ASU) cycle, pumped LOX is typically vaporized and superheated against a boosted stream of air (or nitrogen). The idea is to eliminate the aftercooler of the booster compressor and pass the boosted gas direct to the pumped LOX exchanger. The air (or nitrogen) booster compressor, typically includes an aftercooler so that the boosted gas is supplied to the pumped LOX exchanger at ambient temperature. This is particularly important if the pumped LOX exchanger is of the aluminium plate fin type, as such exchangers have limited upper design temperatures.
