A method for reducing furnace fouling in a delayed coking process comprising (a) supplying at least one feed to a delayed coking unit comprised of coker furnace, at least two coke drums and a coker fractionator, (b) increasing the aromaticity of the feed to produce a modified stream by combining with the feed upstream of the coker furnace at least one added stream selected from the group consisting of an aromatic gas oil, a hydrotreated aromatic gas oil and combinations thereof, (c) introducing the modified feed stream into the coker furnace, d) heating the modified feed stream to a coking temperature in the coker furnace to produce a heated modified stream, and e) transferring the heated modified stream from the coker furnace to a coke drum.

Method for reducing fouling of coker furnaces

A separation apparatus for removing particulate material from a flash zone gas oil stream produced in a delayed coking unit. The apparatus of the invention employs cyclonic separation to remove particulate material from the flash zone gas oil stream. The stream can then be further processed, for example by passing the stream to a fixed bed catalytic hydroprocessing unit and then to a fluidized bed catalytic cracking unit, or to other processing units, thereby enhancing the value of the flash zone gas oil stream.
