Features and Benefits

The most advanced design in the industry:

  • DuPont BELCO® can offer Process Design Packages, Material Supply, or even Turnkey projects.
  • Control particulate emissions to below 50 mg/Nm3 (depending on regenerator cyclone performance) at a fraction of the cost of an Electrostatic Precipitator (ESP).
  • A separation cutpoint near 2um allows separation of virtually all erosive particles, thus safeguarding your power recovery expander.
  • The robust design allows trouble-free operation at high temperature for many years.
    Even in the event of regenerator cyclone failure, the Shell TSS is a robust safeguard for your Power Recovery unit.
  • DuPont BELCO® is capable of upgrading your existing TSS unit with the latest Shell Global Solutions technology.
