Technologies -
Resodyn Corporation's chemical process technology extends
to many areas including renewable resources. An example is Chemical
Pulping of Wheat Straw. Resodyn Corporation's unique
ResonantAcoustics® and ResonantSonics® mixing
technologies have also demonstrated dramatic improvements
in a variety of separations processes including Membranes,
Extraction, Flotation, and Crystallization.
Chemical Pulping of Wheat Straw
 |
Resodyn Corporation's
wheat straw chemical pulping technology turns wheat
straw (field residue after harvesting) into pulp
which can be used for specialty applications where
non chlorine bleached paper is required or desired.
The pulping operation is an environmentally friendly
(green - chlorine free and low water use) process
that produces a product from waste that can be
sold at a premium. |
Features:
• Produces chlorine bleach free
paper pulp
• Environmentally friendly
• Suited
to system of small operations
• High brightness
• Potential for
other byproducts
Benefits:
• Provides extra income to farmers/ranchers
for waste product
• Alternative to burning
that is becoming environmentally unacceptable or banned
• High
quality product yielding a premium price
• Conserves
trees
• Domestic source of pulp
• Provides rural
area jobs
Applications:
• Farmer co-operatives
• Corporate farms
• Agri-businesses

Membranes
|
In almost all filtration
applications concentration polarization causes
gel layer formation on membrane surfaces resulting
in a reduction of flux. The eventual result of
gel formation is membrane clogging. Resodyn Corporation
has developed a unique sonic technology that induces
micro turbulence in the fluid near membrane surfaces
minimizing gel layer formation. This results in
maintenance of high flux through membranes on a
continuous basis. Resodyn Corporation has developed
unique membrane separation technology based on
ResonantAcoustics® that separates products
in situ and does suffer from clogging. |
Features:
• Reduced cost processing
• No product separation and purification required
• Lab to production plant capability
• Solutions tailored to the application
Benefits:
• Increased conversion and yield
• Lower net cost
• Waste streams minimized
• Environmentally friendly (green)
Applications:
• Biochemical reactions with shear
sensitive enzyme catalysts

Extraction
|
Resodyn Corporation
also has a unique technology using ResonantSonics® that
improves continuous industrial extraction processes
by dramatically improving liquid-liquid mixing.
This technology operates in the
audible spectrum. |
Features:
• Capable of continuous flow or
batch applications
• Industrial scale-up possible
• No rotating seals
Benefits:
• Improved extraction rate
• Faster coalescing rates
• Smaller footprint
• Decreased solvent inventory
• Decreased solvent losses
• Lower net cost
Applications:
• Mining separation processes such
as solvent extraction
• Industrial chemical processes (e.g. foods, drugs, flavors, aromas,
etc.)

Flotation
|
Resodyn Corporation
also has a unique technology using ResonantSonics® that
improves continuous industrial flotation processes
by dramatically improving bubble dynamics during
flotation processing. This technology is capable
of gas hold-up values that are nothing short of
outstanding. Current microbubble flotation processes
using small bubble jets and static mixers are incapable
of the mass transfer and the bubble pumping dynamics
of a ResonantSonics® flotation column. |
Features:
• Capable of continuous flow or
batch applications
• Industrial scale-up possible
• Can be retrofitted into many reactors
Benefits:
• Increased recovery of fine materials
• Lower net cost
Applications:
• Mining processes such as copper
and coal final stage flotation

Crystallization
|
The dominant purification
technology for solids is crystallization. The crystallization
process can effect the size distribution of crystals
as well as their purity. In many cases size distribution
is a critical product specification. Resodyn Corporation
has a unique purification technology that improves
crystallization by using low-frequency sonic agitation.
The Resonant Enhanced Crystallization ( REC
) technology has been found to greatly improve
the crystallization process in terms of crystal
growth rate, size distribution and purity. |
Features:
• Uniform micro mixing
• Low shear without compromise in mass transport
• Crystals grow at the same rate
• Greatly improved reaction selectivity
Benefits:
• Increased Crystal Growth Rate
by more than 150%
• Improved Crystal Size Distribution by 95%
• Improved Crystal Purity by 245%
• Increased Crystal Yield by more than 90%
• Reduced Crystal Breakage and Secondary Nucleation
Applications:
• Petrochemicals industry purification
of solid compounds
• Drug purification in the Pharmaceutical industry
• Purification of crystalline food products
