METHOD AND DEVICE FOR PRELIMINARY HEATING OF RAW MATERIALS BY MEANS OF COOLER OF WASTE GASES Russian patent published in 2013 - IPC C10G11/18 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to heat recovery of waste gases discharged from a catalyst regenerator. The invention relates to a device for catalytic conversion of hydrocarbon raw materials, comprising a reactor for contact of hydrocarbon raw materials with the catalyst to produce cracking products and the coked catalyst; a line of raw materials supply that communicates with a reactor; a pipeline for a catalyst designed for transportation of the regenerated catalyst to the specified reactor; a generator for coke burning from the coked catalyst with production of the regenerated catalyst and waste gases; a pipeline for the coked catalyst communicating with the specified reactor and the specified regenerator, a line for transportation of waste gases serving for transportation of waste gases from the regenerator; and a heat exchanger of preliminary heating of raw materials, the first side of which communicates with the line of waste gas transportation, and the second side communicates with the specified line of raw materials supply, designed for implementation of heat exchange of waste gases with hydrocarbon raw materials. The invention also relates to the method of catalytic conversion of hydrocarbon materials.

EFFECT: improved heat recovery of waste gases discharged from a catalyst regenerator, reduced quantity of coke and formation of carbon dioxide.
