| titleOfInvention | Method and apparatus for separating air to produce an oxygen product |
| abstract | A method and apparatus for separating air to produce an oxygen product in which air is separated within a double column arrangement. In the double column arrangement part of the air to be separated reboils a lower pressure column and is then introduced into the higher pressure column for separation. Another part of the air is partially cooled and then expanded with the performance of work and then introduced into the lower pressure column to supply part of the refrigeration requirements. The remaining part of the refrigeration requirements is supplied by partially vaporizing a crude liquid oxygen stream within a head condenser used to produce reflux for the higher and lower pressure columns. The partially vaporized stream is then phase separated into liquid and vapor phases. The liquid phase is introduced into the lower pressure column and the vapor stream after having been partially warmed is turboexpanded to provide the remaining refrigeration requirements of the plant. |
