Abstract
The invention pertains to the field of oil refining and the petrochemical industry. The proposed plant for the distillation of a liquid has a vacuum rectification column with pipes for feed of a stock product and for bleeding of a gas-vapor phase and at least one liquid fraction; and a vacuum-producing device composed of a liquid-gas jet apparatus, a separator, a pump and a condenser. The gas intake of the liquid-gas jet apparatus is connected to the pipeline for bleeding of a gas-vapor phase, the liquid intake of the jet apparatus is connected to the discharge side of the pump and the outlet of the jet apparatus is connected to the condenser's intake. The intake of the separator is connected to the condenser's outlet, the liquid outlet of the separator is connected to the suction side of the pump and the gas outlet of the separator is connected to consumers of compressed gas. There is a variant of the invention wherein the condenser is furnished with an additional liquid intake, which is connected to the discharge side of the pump. Another variant of the invention is when the condenser is connected to the pipeline for bleeding of a liquid fraction from the rectification column. In…
