Krebs Cyclones for the Chemical Industry
The Krebs Cyclone is a low cost, free vortex centrifugal
device used for separating solids from solid/liquid suspensions.
Krebs Cyclones are used to concentrate feed slurries to
centrifuges and filters in order to increase their capacity or to
permit the use of smaller machines of lower horsepower. In
many chemical process applications, cyclones may be used in
place of centrifuges, filters, gravity settlers, or other more
expensive solid/liquid separation devices.
Cyclones that are used in the chemical industry typically have
a continuous underflow discharge but they can also have
accumulator tanks on the underflow for applications where the
feed solids concentration is very low. Krebs offers cyclones that
can make separations from approximately 10 microns and larger.
The separation size that a cyclone can make is dependent
on the feed characteristics, such as the solid and liquid specific
gravities, the solids concentration and shape, and the liquid
viscosity.
Krebs Cyclones for the chemical industry are available in
sizes ranging from 0.5 to 50 inch [12 to 1270 mm] in diameter.
Krebs has cyclone designs and specifications that meet the
difficult conditions of abrasion, corrosion, temperature, and
pressure that are typically encountered in many processes.
For very fine separations,
Krebs has Small Diameter
Cyclones that can be
manifolded together in vessels
to handle any flow rate. These
cyclones are available in 0.5,
1.0, and 2.0 inch [12, 25, and
50 mm] diameter sizes. The
Krebs fabricated metal cyclones
and vessels can be designed for
any operating pressure or temperature and can be designed to
ASME code,
section VIII division I
specifications.
Krebs Cyclones for the
Chemical Industry can be made of virtually any metal and can be designed
for any pressure and temperature.
The Krebs Close
Packed Manifold
accommodates
many individual
cyclones, each
uniformly fed using
one common feed
nozzle, providing
consistent operation of all units.

Krebs Cyclones have been installed for many different solid/
liquid separations in chemical process industries. The following includes some of the more common applications:
Control of Crystal Size
Washing or filtration of crystalline solids may be improved markedly by
increasing the size of the crystals. Classifying the solids with cyclones, and
returning fine crystals to the crystallizer or reaction vessel may increase the
average size of the crystals.
Thickening Ahead of Centrifuges and Filters
Capacity of filters and centrifuges may be increased by pre-thickening of the
feed solids. Many Krebs Cyclones have been installed for this purpose.
Recovering Catalyst for Reuse
Krebs Cyclones can be used for separation of catalyst from a catalyst/liquid
suspension.
Remove Solids from Scrubber Effluent
Recirculation of gas scrubber effluent is common practice, but granular solids
may cause abrasion and plugging of spray nozzles. Cyclones installed in the
return effluent stream will separate the abrasive solids from the liquids.
