FIELD: machine building.SUBSTANCE: device contains the distillation still with pre-heater, column divided through height by the horizontal partitions. Lines for separate supply of the input feed and carrier are equipped with heaters. Device contains carrier recycling line, product fractions condensation unit in form of the nozzle type fractional column and product fractions outlet branch pipes. In the distilling still the bubbler is installed. The column partitions are partially perforated, and between perforation zones without clearance the pore nozzle blocks are installed. The product fractions outlet branch pipes are installed on the column above planes of the appropriate horizontal partitions. Inlet branch pipe of the feed supply line is installed below the product fractions outlet branch pipes. The device can include feed recycle line from the distilling still connecting to the feed supply line. The bubbler is made in form of the gas-liquid riser with internal circulation. In the distilling still the pore gas-permeable heater is installed above the liquid phase surface of the distillable product.EFFECT: increased productivity, reduced size and weight characteristics.4 cl, 2 dwg, 1 ex |
