Industrial Process Solutions

 Our company owns the International IP on the most advanced
Eutectic freeze crystalliser. The crystalliser was designed and develop by Dr.
Pascual from the University Of Cape Town. He is one of the leading authorities
in the world on crystallisation. The new crystalliser overcame the problem of
continuous function and the electricity cost is lowered by up to 74%. The
production output is raised by an average of 16%.

We are looking for an  investment and or equity partner.

 Novel stirred scraped wall crystallizer designed for
melt and EFC

Many
industrial processes involve one or more streams of electrolyte solutions. Melt
crystallization is well known to be used for liquid purification in
petrochemical and pharmaceutical industries, being the limit of application
eutectic conditions were the solutes start crystallizing. By using this
thermodynamic process no extra chemicals like antisolvents during selective
precipitation or antiscalants to avoid the formation of unwanted salts during
the melt-liquid purification are necessary and therefore lowering significantly
the cost by avoiding extra reagents and consequent disposal fees after
treatment. In the other hand Eutectic freeze crystallization (EFC) has been
reported to be economically more beneficial than the conventional techniques
for the recovery of pure salt or acids and clean water (Van der Ham et al.
1999, Van der Ham et al. 2003, Vaessen et al. 2003). Van der Ham et al. showed
that compared to triple-stage evaporative crystallization savings up to 70% of
the energy consumption could be achieved depending on the type of salt. In an
EFC process salt and ice are crystallized simultaneously at conditions just
below the eutectic point of the aqueous solution. The selectivity of crystal
growth leads to very pure products even when the solution contains many
impurities as is often the case for industrial streams. Impurities can however,
shift the eutectic point of the pure system. During eutectic freeze
crystallization separation of the ice and the salt crystals can be perform
gravitationally within the crystallizer or by centrifugal forces in or out of
the crystallizer due to the difference in density between either the ice or the
salt, and the mother liquor. In previous studies several prototypes of EFC
crystallizers have been developed. The most important design characteristics of
these crystallizers are the heat transfer rate that dictates the production
rate, the residence time, the solid suspension and the separation efficiency,
all them governed by the fluid dynamics in the crystallizer. Several Melt and
EFC crystallizer designs and implementations have been reported in literature.
As an example Vaessen et al. compared the performance of the Cooled Disk Column
Crystallizer (CDCC-1) and the Scraped Cooled Wall Crystallizer (SCWC-1)
(Vaessen et al. 2003). The heat transfer was higher in the CDCC-1 up to 7.2 kW
m-2 compared with the 3.8 kW m-2 of the SCWC-1 due to the more effective
removal of the developing ice scale layer from the heat exchanger surface. The
gravitational separation on the other hand, was shown to proceed more
effectively in the SCWC-1, because settling of the salt crystals and floatation
of the ice crystals was not hampered by the horizontally positioned perforated
cooling disks. However, separation difficulties still occurred at high solid
percentages, and ice scale formation at low scraping rates (Genceli 2008). The
novel Stirred Scraped Cooled Wall Crystallizer has an optimized fluid dynamics
design for higher heat transfer, crystal suspension and for efficient
gravitational separation to increase the throughput.

The
main core of the design was to avoid the common problem of solid body rotation
inside the crystallizer that the earlier scraped heat exchanger crystallizers
used for EFC, cooling, and melt crystallizers used by industry have. Heat
transfer and fluid dynamics were simultaneously investigated by using
thermocromic liquid crystal slurry and crystallization kinetics were
investigated in situ in a continuous crystallizer were crystal size
distribution, morphology and purity of the crystals were determined. This
results were presented and published at the International Conference of Crystal
Growth and Epitaxy 17 proceedings (Rodriguez-Pascual 2013). The results showed
an improved heat transfer and turbulence that derived in a accurately
controllable and evenly distributed supersaturation in the crystallizer. The
accurately control of the temperature derives in a efficient use of the heat
transfer energy and avoids different growth rates in the crystallizer
minimizing the ice scaling behavior. Due to this increase in turbulence,
suspension of the crystals was also controllable and the residence time of
crystals could be decided in terms of their density, morphology and size, and
therefore a product with a desired narrow size distribution was obtained. 

The
apparatus according to the present invention can be used for numerous
applications, such as mineral salts, mineral acids, organic acids, amino acids,
pharmaceutical drugs ,for the recovery of salts and metals from the mining
industry, treatment of acid mine drainage, waste streams and agricultural
industry.
