    Cold Flow Graph BG-1000 has the Best distriBution CharaCteristiCs oF any oF

    the major hiGh void CeramiCs tested.

    Cold flow tests measure the lateral distribution and the resulting flow through that area. This is acheived by injecting a fluid, at a steady flow, through a single source at the top of a bed of the material and measuring the outflow through 253 openings at the bottom of the bed.

  • Ceramic Bed Guards can be incorporated into classical graded bed solutions

    What Our Customers Are Saying:

    We have achieved the longest run life in our lube oil units history. We have also been able to increase feed rates by 15% and still have seen no pressure drop increase after 24 months. Previous runs were typi-cally only 810 months using ring grading systems and feed rate reduc-tions.

    Lube Oil Process Engineer Major Gulf Coast Refinery

    When we order Ceramic Bed Guards from Crystaphase, we are able to order the exact quantity and size we want in custom pack-aging. We avoid the expense of buying extra material that often gets misplaced or forgotten before being used.

    We have achieved the longest run life in the unit history. We have also been able to increase feed rates by 10% and still have seen no pressure drop increase.

    Process Engineer Major West Coast Refiner

    Crystaphases family of high void ceramic Bed Guards gives the refiner gains in both void fraction and surface area when compared to conventional spheres or Rasching rings. This characteristic gives the benefit of both lower pressure drop and improved flow distribution.

    Ceramic Bed Guards (high void ceram-ics) have been used for over 20 years to both help eliminate pressure drop problems and provide better feedstock distribution in top bed applications

    Ceramic Bed Guards are used in liquid, vapor phase and mixed phase applications

    They are successful in trapping large particulate

    All products manufactured in the United States

    Custom sizes available upon request

    Since its introduction in 1998, over 30,000 ft3 of BG-1000 has been used, making it the second most widely used bed guard in the industry

    Cold flow tests show that BG-1000 has the most effective fluid lateral distribution of any material on the market. The lateral distribution properties are the most important aspect in improving performance

    Over 400 successful commercial installations worldwide

    The elliptical openings provide a unique flow pattern

    BG-2000 has proven very popular due to its combination of elliptical and trisoidal openings

    Over 40 successful commercial installations

    Successful applications from the top to the bottom of the barrel

    Ability to shut down for catalyst activity, not pressure drop

    BG-3000 combines both circular and elliptical openings with external fluting

    Unique design incorporating a combination of elliptical, round and fluted ring elements

    Higher density material ideal for hold down and distribution applica-tions

    Good attrition resistance

    BG-4000 is a classically shaped material that has been improved by the use of trisoidsal openings rather than triangular openings

    One of the highest void space materials on the market

    Low initial pressure drop

    Ability to shut down for catalyst activity, not pressure drop
