The design and commercial application of four 1.5 MM TPY super low pressure continuous reformer(SLCR) are introduced. Under different working conditions of main process settings and key equipment selection, four units have been successfully put into production and run smoothly. The results of performance test show that operating parameters are within the design range, the equipment run well, the main technical indexes reach or exceed the design values, the catalyst dust is low, and the flue gas emission meets the environmental requirements. The above results show that the new designed structure of SLCR reactor and regenerator is successful. As for the combined feed exchanger, the heat recovery and energy saving can be achieved by plate heat exchanger or spiral-wound heat exchanger. The waste heat recovery system in the furnace can further recover the waste heat of the flue gas and reduce the exhaust temperature. The main technical indexes, such as aromatics yield and pure hydrogen yield, all reaches or exceeds the design values. The design, construction and production of the four units are successful.
