| titleOfInvention | Method of supplying gaseous oxygen to meet the requirements of different demand patterns |
| abstract | (57) [Summary] (Modified) [Objective] To provide an air separation method for supplying gaseous oxygen that meets the requirements of various demand cycles. [Structure] Air is rectified by a two-stage tower low temperature rectification process to generate a nitrogen-rich vapor in a high pressure column 22 and liquid oxygen in a low pressure column 24. When there is a demand for gaseous oxygen, liquid oxygen is pumped from the low pressure column to heat exchanger 18 and vaporized by heat exchange with the nitrogen rich vapor from the high pressure column to form gaseous oxygen. On the other hand, the nitrogen-rich vapor condensed by the heat exchanger is flushed into the flash tank 54. Flash vapor is added to the nitrogen rich vapor to increase the vaporization rate of gaseous oxygen. The liquid thus obtained is introduced into the lower pressure column as a reflux to enable the withdrawal of liquid oxygen. Excess liquid oxygen and condensed nitrogen not used immediately are stored. |
