Throttle expansion versus isentropic expansion of large air separation unit

Isentropic expansion is more effective than throttle expansion in terms of temperature effect and cooling capacity. Moreover, the expander can also recover part of the expansion work, which can improve the economy of refrigeration. However, the throttling valve is simple in structure, easy to adjust and can work in the gas-liquid two-phase zone. Especially when the initial temperature is low, the cooling capacity of throttling is enhanced, isentropic expansion is weakened and the gap between the...
