Nano Assisted Neutralising
Based on patented technology developed by CTi and exclusively
brought to the oils and fats industry by Desmet Ballestra, the Nano
Neutralization process offers enhanced performance for your refining
operation: improved oil refining yield, lower operating expenses,
reduced environmental impact, excellent oil quality…
This revolutionary new oil neutralization process, which can be
easily added to existing oil refineries, is commercially proven and
will offer you a quick return on investment.

The Advantages of Nano Neutralization Process
Refined oil yield increase by over 0.2%
Improved conditioning of the oil in the Nano Reactors® results
in optimized separation of the heavy aqueous phase from the light oil phase in
the neutralizing centrifuge. Less neutral oil remains in the heavy phase and
overall oil yield is increased.
As much as a 50% reduction in silica usage
Silica can be saved via the optimized separation of the heavy phase from the
light phase in the neutralizing centrifugal separator due to oil conditioning in
the Nano Reactors®. Less soap remains in the neutralized oil phase,
thus reducing the need for silica (or wash water) downstream to remove the
residual soap. Less silica (or wash water) also translates directly to less oil
loss in the spent silica (or spent wash water). Our customers have experienced
as much as a 50% reduction in silica usage!
90% reduction in phosphoric acid consumption
Nano Reactors® significantly
facilitate the removal of non-hydratable phospholipids. As a consequence, the
use of phosphoric acid or citric acid is reduced. With the Nano Neutralization
process, phosphoric acid usage can be substantially decreased or totally
30% reduction in caustic usage
The significantly lower phosphoric acid consumption consequently allows savings
in caustic usage. Caustic addition can be further lowered, due to superior
mixing of the caustic water solution and oil inside the Nano Reactors®,
resulting in a perfect stoechiometric need of caustic to convert all FFA into
soaps without the need for an excess quantity.
Savings in steam consumption and maintenance
Steam can be saved in refineries that presently heat the oil above centrifugal
separation temperature during the acid pretreatment step to enhance the process.
With Nano Neutralization there is no need to heat the oil above centrifugal
separation temperature, thus saving steam.
Repair parts and maintenance costs can be saved in refineries that presently use
outdated high shear mixers and acid reactor to mix the acid into the oil and
provide retention. In these cases, the high shear mixer, pump and tank agitator
are taken out of service. The annual maintenance and repair parts costs for this
equipment far exceeds that of Nano Neutralization.
Nano Neutralization Process described, soon to be “The Industry Standard”
Crude oil or water degummed oil is pumped from the existing acid pretreatment
section through a safety filter, through a totalizing flow transmitter, and into
a small surge tank at a desired process flow rate. The oil is transferred from
the small surge tank to the inlet of a high pressure pump by gravity drainage. A
caustic water solution is injected into the oil between the small surge tank and
the inlet of the high pressure pump from the existing caustic dosing system. The
amount of caustic water solution is automatically controlled via the PLC by a
set-point dosage and the incoming oil flow transmitter data.
Two simple control loops are used to maintain peak performance and protect the
efficient and robust pump feeding the oil and caustic water solution directly
into the Nano Reactor®. The first is a variable frequency drive
adjusts the speed of the pump motor to maintain the optimal operating pressure,
which is critical to the process, to compensate for fluctuations in the flow
rate. The second is a level transmitter mounted in the surge tank is used to
adjust the control valve’s open position in the recycle line to ensure a
constant feed to the pump. These two control loops ensure the Nano Reactor® provides
consistent, efficient, and dependable performance.
The high pressure pump elevates the pressure of the oil plus caustic water
stream to the values from 40 to 80 bar (600 to 1200 psig). Once the oil and
caustic water solution passes through the Nano Reactors®, at the
discharge, fluid pressure returns to typically 3.4 bar (<50 psig).
Once the oil and caustic water solution has passed through the Nano Reactors® it
proceeds on to a retention tank, and then on to the existing centrifugal
After the centrifugal separator, the neutralized oil stream passes through a
totalizing flow transmitter, used to measure the final refined oil yield.
After the flow transmitter the neutralized oil flows on to the silica absorption
system (or water wash system) to remove residual soap.
