FIELD: petroleum processing.
SUBSTANCE: invention relates to low-scale petroleum and gas condensate processing plants. Plant of invention comprises feedstock tank 1, feedstock-supply pump, heating heat-exchangers 3 and 4, vaporizer 6 for separating feedstock into low- and high-boiling fractions, cooler 7 for low-boiling fractions, feedstock sparkler 8, finished product tanks 9, valves, and pipelines. Part of vaporizer 6 is located inside cylindrical coiling heating heat-exchangers 3 and 4 and is made from two telescopically arranged barrel of small (10) and large (11) diameters. Lower end of small-diameter barrel 10 is closed with reflecting cone 12 and generatrix of the barrel has windows 13. Feedstock sparkler 8 is constructed in the form of tube provided with longitudinal slots 14 and disposed in large-diameter barrel 11 closed at its end with blind flange 15.
EFFECT: improved quality of distillation of different fraction-composition hydrocarbon feedstock, increased productivity of small-scale plants, reduced thermal loss, reduced weight and dimensions, and facilitated maintenance of plant.
