FIELD: technological processes.
SUBSTANCE: invention relates to two variants of device for oxidative regeneration of catalyst with nitrogen discharge lines, air and balance gas discharge lines. One of variants includes a reactor, recovery heat exchanger, heater, dust collector, cooler and supercharger, moreover, as the cooler is mounted dephlegmator with discharge line of condensate, equipped with top cooling section of gas dephlegmation discharge line and lines I/o refrigerant, as well as lower heat exchange section connected to reflux gas discharge line, to which discharge lines of balance gas, nitrogen and air are adjacent.
EFFECT: reduction of hydrocarbon and nitrogen losses, reduction of atmospheric pollution by combustion products, as well as prevention of deactivation of catalyst.
