Larox continues to be a Primary Supplier of Solid-Liquid Separation and Processing Solutions to the Zeolite and Fluid Cracking Catalyst Market

LAPPEENRANTA, FINLAND - September 26, 2007 - With over 110 Pannevis vacuum belt
filters and Larox pressure filters installations world-wide ranging from 4A
Zeolite to complex fluid cracking catalysts, Larox is one of the worlds major
suppliers of solid-liquid separation and processing equipment to zeolite based
industries. Recent orders in 2007 continue the trend with sales of both filter
types into various applications in the USA, China, South Africa and Germany. 

4A Detergent Grade Zeolite
The recent market trend is towards using the Larox "C" Series Automatic
Pressure Filter for 4A zeolite, as the typical installation produces a filter
cake containing only 17 - 23% residual moisture thereby reducing considerably
the down stream drying costs when compared to traditional vacuum filtration
methods. 

The "C" Series Automatic Pressure Filter is a fully automatic filter that can
be operated with or without cake washing as needed, but when cake washing is
used for 4A zeolites it provides comparable results to conventional
technologies using the same or less wash water. Production capacities per unit
area are also generally superior to existing technologies and a single Larox
“C” Series filter can replace the two stage process that is common when using
vacuum filters. 

Molecular Sieves
The Pannevis RT horizontal vacuum belt filter from Larox is the preferred
solution for molecular sieves as it is eminently suitable for the multi-step
counter-current ion exchange process required to produce molecular sieves.
Water washes and ion exchange can be carried out on a single machine with up to
seven (7) separate stages possible. The RT filter is renowned for its wash
efficiency and this is also true in the ion exchange stages. 

Fluid Cracking Catalysts
As with molecular sieves, the Pannevis RT vacuum belt filter is the preferred
solution and is widely used for NaY, 31X and ZSM-5 type catalysts as well as
many others. Again the superior washing of the Pannevis filter is a major
reason for the success, while the fully automatic continuous operation provides
a consistent product at all times. Multiple wash steps (usually up to 5, but
can go as high as 8 on a single machine), in either co- or counter-current
configuration or in a combination of both make the filter extremely flexible
and the filters can be easily reconfigured for product changes if required,
usually by simple piping changes. 

The Larox “C” Series filters, the Pannevis horizontal vacuum belt filters and
the full range of Larox products are fully supported by the Larox Service
group, the most comprehensive and experienced network in the industry, covering
