Abstract

An apparatus for producing liquid nitrogen is provided. The apparatus includes a heat exchanger (10), a pair of turbine-boosters (50, 70, 53, 80), a warm compressor (40), an air separation unit (19) having a single column (20), a top condenser (23) and a bottom reboiler (21), a liquid/gas separator (60), and an optional subcooler (30). The apparatus is configured to produce merchant or non-merchant grade liquid nitrogen using the pair of turbine-boosters to provide refrigeration and energy for the process.
