Comparing with gaseous air separation plant, cryogenic liquid nitrogen plant need more cooling consumption.
According to different yield of cryogenic liquid nitrogen plant, we adopt various refrigerating cycle processes, like booster-expanding refrigeration, low temperature pre-cooler refrigeration, recycle compressor with high-low pressure expander refrigeration, etc. to reduce the power consumption.
DCS or PLC system are used, aided by on-site instruments, to make the complete system stable, reliable and easy to operate.
