VRV provides the complete range of main equipment for the UOP CCR Platforming process, used to convert petroleum refinery naphthas with low octane ratings into high-octane liquid products (gasoline). These are:

• Platforming Reactor
• Regenerator
• Feed / Effluent Exchanger (Texas Tower)

In particular the Platforming Reactor consists of three/four adiabatic, radial-flow sections arranged in one or more vertical stacks. Catalyst flows vertically by gravity down the stack, while the charge flows radially across the annular catalyst beds. One of the largest Platforming Reactors supplied by VRV was for the Dung Quat refinery in Vietnam, which was 55-meter long and weighed 145-ton. The partially deactivated catalyst is continually withdrawn from the bottom of the reactor stack and transferred to the Regenerator section. The catalyst flows down through the regenerator where the carbon is burned off and the moisture and chloride levels are adjusted.

VRV has supplied Regenerators in 316L SS and Incoloy 825 materials. The effluent from the last section of the Platforming Reactor runs through the Feed / Effluent Exchanger (Texas Tower) and gives heat to the combined feed (hydrotreated naphtha and recycle hydrogen), which then goes through the fired heaters to reach reaction temperature and finally to the reactor.
