Determination conditions of low temperature and low stress conditions of small air separation unit

Determination conditions of low temperature and low stress conditions of small air separation unit
When the ratio of design pressure to maximum allowable pressure for these components is less than 0.3 at the maximum design temperature, the selection of materials and the manufacturing and inspection requirements are considered according to the temperature obtained after adding 50 degrees Celsius to their design temperature.

In the liquid air separation plant, the cooled refrigerant goes to the air machine through the refrigerant delivery pipeline, and the intercooler cools the compressed air to around 10°C, improving the efficiency of the air compressor and reducing the energy consumption of the air compressor. The air separation unit uses circulating nitrogen to recycle and utilise the CNG cold through a heat exchanger, which in turn liquefies the air to transfer the cold to the liquid air separation plant, an...
