The advantage of using this process design is that the nitrogen cycle compressor and the medium/high/ultra-high pressure product nitrogen press are combined into one machine, eliminating the need to use multiple product nitrogen presses. Due to the high nitrogen to oxygen ratio, a portion of the nitrogen must be extracted from the top of the low pressure tower to make up the nitrogen cycle compressor. This make-up compressor is also combined with the low-pressure/low-pressure product nitrogen pr...
