<p><P>PROBLEM TO BE SOLVED: To provide an internal pressurization type low-temperature air processing equipment allowing to reduce time as the entire plant by automatically optimally evaporating all the times for reducing time of the evaporating process at any temperature state of a low-temperature fluid side such as at the time of 'cold start'. <P>SOLUTION: In this internal pressurization type low-temperature air processing equipment, temperature of liquid oxygen inside a liquid oxygen separator 9 is normally measured and the condition (temperature→pressure) required for oxygen evaporation in the state is automatically calculated for adjusting an operation pressure of an air booster 4 as a supply source of boosted air. <P>COPYRIGHT: (C)2003,JPO</p> |
