Continuous catalytic reforming

The catalytic reformer is central to refinery operations and success. The advent of continuous catalyst regeneration has made a constant, non-declining yield achievable but only under the right operating conditions.

Controlling octane and aromatic compound levels

Many diverse challenges threaten CCR efficiency throughout the various process segments: catalyst addition and removal, chloride injection, and lock hopper blocking and venting.

High operating temperatures, abrasive medium, frequent cycling, and solids are all challenges that can affect valve performance and lifecycle if valves are not specified correctly. There is zero tolerance for error with respect to valve metallurgy and overall ball design. Minor valve design errors will compromise the spherical catalyst integrity, while big mistakes can result in catastrophic failure.

In addition to harsh process conditions, operators are increasing runtimes of CCR units. This, along with the high cycle rate of the process puts considerable stress on the valve, which must continually operate with a high degree of accuracy over longer periods.

The UOP preferred solution

Years of extensive experience and considerable research and development investment, along with proven valve performance has made Metso a leader in the industry. So it comes as no surprise that UOP often use our products as they define flow parameters as they have done for their CCR process. 

Metso valve assemblies for CCR are all designed to meet UOP Specification 671. They handle extreme temperature swings and highly corrosive media, including chlorides, by using materials, coatings and seat designs specifically engineered to resist abrasion and potential issues related to asynchronous thermal expansion.

 In addition to providing valves for these severe applications, Metso also supplies a host of general-purpose products, complied with smart technologies, for use in CCR applications. Either way, severe or general-purpose, Metso will deliver the best safety outcomes with the reliability and accuracy to boost overall process efficiency

  • Lock hopper valves for 30 000 cycles and more
  • Predictive maintenance reduces cost and increases performance
  • Maximize process uptime
  • Design and metallurgy produce longer product lifetime cost of ownership
  • Compliance with the toughest requirements, such as UOP

 

Optimize your CCR valve package

When CCR’s operate more efficiently and reliably profits go up. But, it’s a demanding application with many critical considerations. Find out how Metso can help.
