摘要： The invention is a method for cracking heavy oils to olefins. In parallel streams, the heavy stream and a steam diluent are heated 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. The hot, olefinic stream acts as both a diluent and a heat source for cracking the heavy oil to an olefin containing product.

摘要： A process and system for the production of olefins from heavy hydrocarbon feedstocks. A heavy hydrocarbon feed is first pretreated at high pressure and moderate temperatures to preferentially remove coke precursors in a liquid product. The pretreated hydrocarbon is then separated into lighter and heavier fractions; the lighter fraction being further thermally cracked to produce olefins.

摘要： An enhanced hydrocarbon pyrolysis reactor for the production of olefins. The reactor provides enhanced heat transfer, reduced pressure drop, and reduced energy requirements while increasing selectivity and olefin yield. The radiant section tubes of the reactor, according to the invention, are shaped to provide a continuously increasing volume per unit length from inlet to outlet of the reactor. This increase in volume may be achieved by either expanding the effective inside radius of the reactor tube and/or increasing the outside radius of the tube while increasing the inside effective radius. Alternatively, since embodiments of reactors according to the invention have internal fins, the fin size and shape may be modified to provide the required increasing volume per unit length.
