FIELD: oil refining, petrochemical and chemical industries. SUBSTANCE: the offered method includes regulation of temperature in zone of side-cut distillate by changing the flow rate of circulating reflux which is effected with preliminarily cooled residual fuel oil supplied to tower over supply zone below the lower side-cut distillate. Temperature difference between supply zone and still is regulated by variation of steam flow rate depending on variation of pressure difference on straight vertical part of pipeline supplying oil from furnace to tower and pressure difference between supply zone and still. EFFECT: higher efficiency. 1 dwg
