Abstract: The engineering design and commercial operation of 2.2×10⁶ t/a CCR unit in Guangxi Petrochemical Company is discussed. The technical features of the process and engineering are described and the running calibration results are analyzed. The analysis result shows that the purity of reformed H₂ and the yield of reformed gasoline both reach or exceed the design specifications, and energy consumption reaches the advanced level in China. All of these demonstrate that the process technology and engineering design are successful.
