    Scallops inside the radial flow reactors are for flow collection or distribution.
    It is generally D-shape, extending parallel to the inner vessel wall,
    and its inner layer delimits the outer layer of the catalyst bed.

    Main Equipment
    Continuous Catalytic reforming (CCR) unit

  • The mechanical design of the equipment considers the loads generated in operation.
  • Also, after defects being revealed in field tests and feedback being given during the transitional heating, cooling and regeneration stages, the design is correspondingly enhanced.
  • The verticality and straightness of the outer basket are measured by laser, and the roundness is controlled within a certain error range.
