High purity nitrogen air separation FAQ

Interpretation of nitrogen cycle working condition of liquid air separation plant

When the demand for oxygen increases higher than the normal working condition, more liquid oxygen is extracted from the liquid oxygen storage tank, pressurized to the required pressure by the liquid oxygen pump and sent into the main heat exchanger after gasification and reheating, and the liquid oxygen stored in the liquid oxygen storage tank is consumed. At the same time, the flow of low-pressure expander will be reduced, and more cold volume will be recovered by high-pressure nitrogen and the...
