Continuous Catalyst Regeneration (CCR) Platforming

Applications | Continuous catalyst regeneration ccr

The world's leading fans for catalyst regeneration*.

No one knows more about fan technology for the catalyst regeneration process in oil refineries than Howden. As the leading global supplier of fans for this application, Howden has installed hundreds of fans for the catalyst regeneration process around the world. Our products are designed according to recognized global industry standards for the continuous regeneration process.

With over 40 years of supplying fans, our Garden City brand of specialist fans continues to set the standard for the chlorination and regeneration and cooler blowers used in the catalyst regeneration process. The catalyst regeneration process allows continuous regeneration of a controlled quantity of catalyst and is used for reforming applications by refineries. Fans for these applications are critical to the process and therefore need to be extremely reliable to minimize costly downtime.

Top manufacturing capabilities and project management support

Our fans are designed by a team of highly experienced engineers and designers, and are manufactured by our network of qualified manufacturing partners. The tools we use to design and fabricate are state of the art, including CAD/CAM, computerized plasma burning machines, CNC lathes, MIG welders, and dynamic balancing equipment.

During the fan fabrication process, we design, construct and test to the highest quality. Welding requirements meet the stringent AWS D14.6 standard for rotating machinery and AWS D1.1 for static components, qualifying them to fabricate fans to your most stringent specifications.

The manufacturing process is initiated by a testing and traceability procedure used to check the quality of the alloy rich materials used to fabricate your fans for conventional and high pressure catalyst regeneration process fans. Throughout the process, controlled audit procedures monitor the efficiency of our operation. These procedures are openly reviewed by our customers, and are frequently witnessed by the refinery’s quality assurance inspectors in addition to Howden inspectors.

Garden City fan in transit

Garden City Fans are designed with quality and total cost of ownership in mind; and with service centers around the world, we remain committed to provide the parts and service our customers need to mitigate downtime. Combining Howden’s 160 years of history with 40 years of experience supplying fans for the catalyst regeneration process, our customers can count on Howden to deliver quality products.

Reliable fans for catalyst regeneration process

Garden City Fans (shrouded and un-shrouded designs), used for conventional and high pressure catalyst regeneration applications, are designed to operate efficiently at continuous high speeds and temperatures (typically between 500°C and 850°C). Fans for this process are manufactured for lasting performance due to their purposeful design with rigid double walls, and filled with high density insulation.

This unique, double wall insulated housing acts to reduce heat loss while adding personnel protection. Standard fan features include a custom fabricated monoblock bearing assembly, nitrogen purged Shaft Seal, and custom designed fan wheels with a focus on efficiency and reliability.

Various bearing lubrication methods are available for the monoblock bearing assembly including static oil, forced lubrication, or oil mist lubrication. Temperature and vibration monitoring equipment is also available to provide long term protection and reliability for the monoblock bearing assembly.

High pressure catalyst regeneration fans are very stable, typically with a minimum of 12mm thick casing, bracing on 150mm centers, rigid sub-base mounting, tight anchors on the inlet, and anvils in the housing to resist forces. Every fan we manufacture for high pressure catalyst regeneration is built and tested to withstand 150 psi (1034 kPa) hydrostatic pressure.

Quality and performance is in our DNA

Howden Garden City Fans was one of the first manufacturers to develop a product for the platforming process and has been a global market leader for over 40 years.

Quality through engineering

Our catalyst regeneration process AMCA test laboratory continually conducts performance tests, sound measurement, and stress analysis to meet our current needs, as well as developing future products.

Every Garden City high temperature fan supplied by Howden is thoroughly inspected and tested. This quality assurance is integral to our leadership in the industry. The Quality Assurance team works independently from our manufacturing group to ensure autonomy. Non-Destructive Test (NDT) procedures such as magnetic particle, liquid dye penetrant, radiograph, and ultrasonic testing are used to ensure the quality of the welds.

Garden City Fans

  • Our fans have set the standard in high temperature applications.
  • We offer a diverse selection of fans for operations up to 1100°C. For applications over 1400°C, special enriched alloys such as Inconel®, Monel®, Incoloy®, Hastelloy® and others are selected based on the customer's specifications and a variety of computer analytical techniques.
  • Our engineering staff has many years of fan experience, as well as a thorough knowledge of materials and stress analysis to select the correct product for each application.
  • As a charter member of AMCA, Howden has contributed to setting many of the standards used throughout the industry today.
