The Advantages of Nano Neutralization ProcessGrey-Nanoinclosed

Refined oil yield increase by over 0.2%

Improved conditioning of the oil in the CTi Nano® Reactor 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 CTi Nano® Reactor. 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

CTi Nano® Reactor 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 eliminated.

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 CTi Nano® Reactor, 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Repair parts and maintenance costs can be saved in refineries that presently use outdated high shear mixers and acid reactor to mix the acid into the oil and provide retention.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 CTi Nano® Reactor, at the discharge, fluid pressure returns to typically 3.4 bar (<50 psig).

Once the oil and caustic water solution has passed through the CTi Nano® Reactor it proceeds on to a retention tank, and then on to the existing centrifugal separator.

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.
