Abstract
The invention is a pyrolysis furnace for cracking heavy oils to olefins. The furnace includes a convection zone and a radiation zone. In parallel streams, the heavy stream and a stream diluent are heated in the convection zone to the point of partial thermal cracking while in the other stream a lighter oil and steam are cracked to produce olefins. The hot, olefinic light stream is then mixed with the heated heavy stream and further cracked in the radiation zone.
