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.

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.
Bed Guards BG-1000 BG-2000 BG-3000 BG-4000
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
