System to increase capacity of LNG-based liquefier in air separation process
The capacity of a nitrogen liquefier (2) cooled by LNG (194) and providing refrigeration to a cryogenic air separation unit (1) is increased by provision of a supplemental compressor (3) separate from the existing compressor(s) in the liquefier unit to boost the pressure of at least a portion of low...

Summary: | The capacity of a nitrogen liquefier (2) cooled by LNG (194) and providing refrigeration to a cryogenic air separation unit (1) is increased by provision of a supplemental compressor (3) separate from the existing compressor(s) in the liquefier unit to boost the pressure of at least a portion of low pressure nitrogen (182) from a dual column distillation column system (114,116) to create additional or replacement feed (184) to the LNG-based liquefier (2). |
