FIELD: petroleum chemistry. SUBSTANCE: apparatus has rectifying columns, device for catalytic reprocessing of raw material to supply heat to rectifying columns, heat-exchanging, capacitive and separating equipment. Device for catalytic reprocessing and supplying heat to rectifying columns has reactor-thermal units, each made in the form of circulation gas duct with heat-generator, shell-and-tube type reactor, heater, shell-and-tube type evaporator and exhaust fan positioned in series downstream of gaseous heat-carrier flow. Apparatus may be further provided with unit for obtaining regeneration gas from reactor- thermal unit flue gas. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 2 dwg
