Cryogenic Liquid Oxygen Plant

Cryogenic liquid oxygen plants solve the technical problems of gas volatilization when filling low-temperature gas cylinders. The liquid oxygen filling device of the low-temperature gas cylinder includes a liquid oxygen tank and a low-temperature gas cylinder. The low-temperature gas cylinder is equipped with a liquid phase valve and gas phase valve respectively.

Compared to gaseous air separation plants, cryogenic liquid oxygen plants need more cooling consumption.

According to the different yield of cryogenic liquid oxygen plants, we adopt various refrigerating cycle processes, like booster-expanding refrigeration, low-temperature pre-cooler refrigeration, and recycling compressor with high-low pressure expander refrigeration, etc. to reduce the power consumption.

DCS or PLC systems are used, aided by on-site instruments, to make the complete system stable, reliable, and easy to operate.
