Abstract

There is a growing demand for liquid air separation products, especially in the liquid oxygen. For their production in large quantities air separation units (ASU) is applied, which work in cycles of two pressures. In cases when the demand for liquid oxygen up to 1000 kg/h, it`s possible to use the scheme with one medium pressure. The rates of ASU average pressure in the circuit which included expander-compressor unit (ECU) are analyzed. Its comparison with ASU, containing low-temperature refrigeration machine showed that the specific energy consumption can be reduced by using ECU from 1.12 to 1 kWh/kg of liquid oxygen.
