FIELD: oil refining industry.
SUBSTANCE: invention relates to equipment for hydrotreating middle distillate fractions. Invention relates to an energy-efficient unit for stabilizing a hydrogenate of a diesel fraction, which includes a reverse stroke of a "raw mixture/hydrogenate" heat exchanger, a first cooler, hot separator with lines of heavy fraction and vapors of light fraction, second cooler, cold separator with lines of circulating hydrogen-containing gas and light fraction, note here that heavy fraction line is connected with light fraction line to make their mix line communicated with stabilization column equipped with third cooler, reflux tank and heater. Heat exchanger "heavy fraction/hydrogenate" is installed as return stroke of "raw mixture/hydrogenate" heat exchanger, heat exchanger "part of crude diesel fraction/hydrogenate" is installed as the first refrigerator, and the line of the mixture of light and heavy fractions is equipped with a reducing device and is directly connected to the middle part of the stabilization column. Invention also relates to an energy-efficient unit for stabilizing a hydrogenate of a diesel fraction.
EFFECT: reduced power consumption.
