Abstract

See full text

A method is provided for producing vacuum in a vacuum oil-stock distillation column and includes pumping a gas-vapor medium out of a column by an ejector into a condenser; feeding a gas mixture and a high-pressure gas into a second gas-gas ejector from which the vapor-gas mixture is fed into a second condenser. A condensate is directed from the condensers into a separator in which the condensate is separated into a water-containing condensate and a hydrocarbon-containing condensate. The hydrocarbon-containing condensate is removed while the water-containing condensate is fed into a steam generator in which heat is supplied to the water-containing condensate from a hot distillate removed from the vacuum column and steam is produced from the water-containing condensate, the steam is fed as a high-pressure gas into the gas-gas ejectors. A plant for carrying out the method is also provided.
