【 摘 要 】

References(10)Cited-By(5)Tubular fouling by coke deposition on its inner wall has restricted the development of a high-conversion furnace for residual oil. Such a furnace is desirable from the viewpoint of economics and operability. The proposed tubular fouling model well represents the complex phenomena of tubular fouling of a residue conversion furnace by modeling a sedimentation of coke precursor and its reaction into coking material in and out the boundary film. The model was developed from the experimental data of a bench unit which was specially equipped to generate a high linear velocity and conversion at the same time, and was verified by data collected in a commercial unit.
