1. Способ работы насосно-эжекторной установки для перегонки жидкого продукта, включающий подачу разделяемого жидкого продукта в ректификационную вакуумную колонну, разделение его на парогазовую фазу и, по меньшей мере, одну жидкую фракцию, подачу насосом жидкой рабочей среды в сопло жидкостно-газового струйного аппарата, откачку парогазовой фазы жидкостно-газовым струйным аппаратом, смешение в последнем парогазовой фазы с жидкой рабочей средой с одновременным сжатием парогазовой фазы и образованием парогазожидкостной смеси и разделение в сепараторе смеси сред на жидкую среду и сжатую газообразную составляющую, отличающийся тем, что в качестве жидкой рабочей среды в сопло жидкостно-газового струйного аппарата подают жидкую рабочую среду с давлением насыщенных паров не ниже давления в вакуумной ректификационной колонне, в сепараторе поддерживают давление, составляющее от 1,1 до 160 давлений парогазовой фазы ректификационной колонны на входе ее в жидкостно-газовый струйный аппарат, а после смешения парогазовой фазы и жидкой рабочей среды, до подачи этой смеси сред в сепаратор, но после выхода смеси из жидкостно-газового струйного аппарата, организуют процесс конденсации в жидкой рабочей среде легко конденсируемых компонентов парогазовой фазы с формированием газожидкостной смеси, которую затем в сепараторе разделяют на сжатую газообразную составляющую и жидкую среду с отводом последней в качестве жидкой рабочей среды.1. The method of operation of a pump-ejector installation for distillation of a liquid product, comprising supplying a shared liquid product to a distillation vacuum column, separating it into a vapor-gas phase and at least one liquid fraction, pumping a liquid working medium into a nozzle of a liquid-gas jet apparatus pumping the vapor-gas phase with a liquid-gas jet apparatus, mixing in the last vapor-gas phase with a liquid working medium while simultaneously compressing the vapor-gas phase and forming a gas-vapor mixture and separation in the separator, a mixture of media on a liquid medium and a compressed gaseous component, characterized in that as a liquid working medium, a liquid working medium with a saturated vapor pressure not lower than the pressure in the vacuum distillation column is supplied to the nozzle of the liquid-gas jet apparatus, the pressure is maintained in the separator, constituting from 1.1 to 160 pressures of the vapor-gas phase of a distillation column at its inlet into a liquid-gas jet apparatus, and after mixing the vapor-gas phase and a liquid working medium, until this mixture of media is fed into the sep the radiator, but after the mixture leaves the liquid-gas jet apparatus, the process of condensation in the liquid working medium of the easily condensable components of the vapor-gas phase is organized to form a gas-liquid mixture, which is then separated into a compressed gaseous component and the liquid medium with the latter being discharged as a liquid working medium . 2.

The method according to p. 1, characterized in that after mixing the vapor-gas phase and the liquid working medium, the liquid fraction of the distillation column is fed into the resulting mixture of media under pressure due to this pressure at the outlet of the liquid-gas jet apparatus, and during mixing with the liquid fraction, condensation is organized in the last and in the liquid working medium of the easily condensable components of the vapor-gas phase with the formation of a gas-liquid stream, which is fed to the condenser and then to the separator, followed by its separation in the separator a torus to a compressed gaseous component and a liquid medium with a discharge of the latter from the separator as a liquid working medium to the pump inlet. 3. Способ по п. 1, отличающийся тем, что в жидкую рабочую среду после выхода ее из сепаратора подают под напором жидкую фракцию с передачей жидкой рабочей среде части кинетической энергии жидкой фракции и окончательным формированием, за счет смешения указаниях выше жидких сред, состава жидкой рабочей среды, которую подают на вход насоса. 3. The method according to p. 1, characterized in that after the liquid leaves the separator, the liquid fraction is fed under pressure to the liquid working medium and part of the kinetic energy of the liquid fraction is transferred to the liquid medium and the formation is finalized by mixing the above liquid media and the liquid composition working medium, which is fed to the pump inlet.
