Abstract
A process and a system for the low-temperature separation of air by rectification is provided. A liquid fraction is obtained in a rectifying system, stored in a tank and at least a portion of the liquid fraction taken out of the tank and brought to an increased pressure. During normal operation, the liquid fraction, which was brought to an increased pressure, is heated in a preheat exchanger and evaporated in the main heat exchanger. During an operating disturbance, at least a portion of the liquid product is removed from the tank, evaporated and used for an emergency supply.
