Abstract
The invention relates to the field of petrochemical industry. The essence of the invention: is a vacuum-producing device, comprising a liquid-gas jet apparatus, a separator and a pump, is furnished with a mixer. The gas inlet of the liquid-gas jet apparatus is connected to the pipeline for export of a gas-vapor phase from a rectification column, the liquid inlet of the liquid-gas jet apparatus is connected to the discharge side of the pump, the outlet of the liquid-gas jet apparatus is connected to the separator, the gas outlet of the separator is connected to consumers of compressed gas, the outlet of the mixer is connected to the suction side of the pump, the inlet of the mixer is connected both to the pipeline for export of a liquid faction from the rectification column and to the liquid outlet of the separator. The offered jet pump vacuum-producing unit is more effective, more capable and less harmful to the environment in comparison to existing units.
