Abstract: Introduced are the engineering design and startup of 300 kt/a catalytic reforming unit in Golumd refinery. Considering the project involving the relocation or reuse of the existing devices and the characteristic of the blending FCC gasoline in the pre-processing part of the unit, three technical measurements (catalyst graded loading, raw material filtration and dehydration, and feed mixture ratio control) were adopted. The scheme of reforming process technology and equipment reuse was also determined. Golmud refinery 300 kt/a catalytic reforming unit has been running smoothly since feeding nearly 1 year, the technical and economic indicators meet or exceed the design requirements. The blending of catalytic cracking gasoline relieves the shortage of reforming feedstock. The sulfur content of the catalytic cracking middle distillate is also reduced. The total construction investment reduces by around 40%, and the energy consumption of the unit is effectively lowered.
