Abstract: The design characteristics of the 3.8 MM TPY CCR unit in Zhejiang Petroleum & Chemical Co., Ltd. are as follows: the layout of reforming reactors adopts“3+2” two row overlapping type, and optimized trapezoidal tube structure is selected for sector cylinder; the reaction furnace is consisted of feed furnace, the third and the fourth intermediate furnace, while the first and the second intermediate furnace are equipped with two series furnaces combined as one box furnace and a set of waste heat recovery system; the compressor adopts the parallel design of reforming hydrogen cycle machine and reforming hydrogen supercharger, in which the reforming hydrogen supercharger selects “one drive three” form, that is, a steam turbine drives three compressors. The calibration results of full load operation of unit are analyzed. The yield of aromatics is 76.04%; liquid yield of C⁺₅ is 88.21%; the yield of pure hydrogen is 4.37%; the amount of catalyst dust is 8.38 kg/d; the energy consumption of unit is 3,425.008 MJ/t. The purity of hydrogen produced by CCR unit and the reformate provided to aromatics unit are close to the design requirements, which shows the feasibility of technology and engineering design of the unit. At the same time, it has important reference significance for process selection and engineering construction of large-scale CCR unit.
