Plant for the distillation of a liquid product

A plant for distillation of a distillation product, comprising:

• a vacuum rectification column having a first pipeline for feed of a stock product, a second pipeline for bleeding of a gas-vapor phase and a third pipeline for bleeding at least one liquid fraction;
• and
• a vacuum-producing device including a liquid-gas jet apparatus, a separator and a pump, wherein the vacuum-producing device further includes a condenser, and wherein a gas intake of the liquid-gas jet apparatus is connected to the second pipeline for bleeding of the gas-vapor phase, a liquid intake of the jet liquid-gas apparatus is connected to a discharge side of the pump, an outlet of the liquid-gas jet apparatus is connected to an intake of said condenser, an intake of the separator is connected to an outlet of said condenser, a liquid outlet of the separator is connected to a suction side of the pump, a gas outlet of the separator is connected to consumers of compressed gas, and said condenser has an additional liquid intake which is connected to the discharge side of the pump.
