FIELD: heating.
SUBSTANCE: invention relates to a supercritical separator equipped with a heater of an extract phase and a waste heat exchanger. A hydrocyclone device is installed as a separator. It is connected to a three-sectional vertical column unit containing an upper heat recovery section as a waste heat exchanger, a middle thermoseparation section, a lower thermoseparation section as a heater of an extract phase, and an isothermal separation zone located between the middle and the lower thermoseparation sections and equipped with a distribution device adjacent to the lower thermoseparation section. With that, the middle thermoseparation section is separated from the heat recovery section by means of a semi-blind partition equipped with an axial pipeline located in intertubular space of the heat recovery section. The latter consists of an assembly of heat exchange elements located in annular space formed with the housing of the section and the axial pipeline equipped with extract inlet lines and lines for supply of heated extract to the hydrocyclone device, as well as it includes a regenerated solvent outlet line. The middle and the lower thermoseparation sections consist of assemblies of heat-mass-exchange elements equipped with heat carrier inlet/outlet lines, and the lower thermoseparation section is additionally equipped with an extract phase outlet line enriched with an extracted substance; besides, the hydrocyclone device is equipped with lines for supply of solvent and extract phase to the isothermal separation zone.
EFFECT: reduction of losses of a solvent with an extract phase and increasing the depth of solvent regeneration.
