The Controlled Cavitation – CFC™ (Controlled Flow Cavitation)  provides increased contact surface in the molecules for greater interaction and efficiency of the inputs (acid, base and catalyst), in order to obtain the reduction of the consumption at stoichiometric levels and even, in some cases, the elimination of later steps, for example, the mitigation of soaps (washing or silica) in chemical neutralization.

In the Vegetable Oil and Derivatives segment, CFC™ is applicable in chemical neutralization (pre-treatment of vegetable oils or animal fats) and transesterification (biodiesel production). The technology provides the following additional benefits:

  • Hydrodynamic cavitation can occur in any turbulent fluid.

    Increasing the speed of the fluid results in a reduction in pressure, thereby reducing the steam pressure.

    The fluid vaporizes due to the low pressure and forms the bubbles of the cavitation. At the extremities of this physical phenomenon, small amounts of steam are released. These form smaller bubbles, from 100 nm to 3 mm in diameter. The smaller bubbles implode under the high pressure that surrounds them. This process of formation and collapse is called cavitation.

  • Cavitation is an extremely powerful process.

    Conditions in the collapsing bubble can reach 5000⁰C and 1000⁰C for some nanoseconds. The implosion occurs during the cavitation process in milliseconds and releases high shear energy in the form of shock waves. The power of these waves generated by the process of cavitation evenly breaks everything in its path. The characteristic of the waves, destructive or productive, will depend on the Arisdyne project, as well as on the control of the cavitation region.

  • How does hydrodynamic cavitation differ from ultrasonic cavitation?

    Ultrasonic cavitation depends on a source of vibrations. This makes ultrasonic cavitation difficult or impossible to stagger and often creates heated zones in the dispersion/emulsion. The maximum or minimum flow restrictions for the CFC™ system relate to the pump’s ability to achieve the required pressures and maintain constant flow through the cavitation region.

  • Will the use of the CFC™ imply a higher rate of wear on my equipment?

    As most people know, uncontrolled cavitation is a very destructive force. The CFC™ system is designed to produce only controlled cavitation. Optimum process conditions also protect your equipment from damage. In fact, CFC™ systems are designed to last longer using static versus dynamic configuration. There are no moving parts in the device.

  • E se um dos reagentes for um particulado?

    CFC™ works equally well on solid and liquid reagents. The solids are fragmented into smaller pieces (100 μm to 3 μm in diameter). Smaller particles give better dispersion and larger surface area.
    Much research has been done on the prevention of uncontrolled cavitation. This form causes damage to turbulent flow systems. However, Arisdyne Systems patented hydrodynamic cavitation technology harnesses the power of cavitation safely to preserve equipment life.
    CFC™ (Controlled Flow Cavitation™) controls the location, size, density and intensity of bubble implosions. The system is calibrated to produce optimum process conditions. Impulse waves resulting from the implosions affect the surrounding process fluid. Minor droplets or particles result in the production of high quality emulsions and dispersions.
    Engineers have established that Controlled Cavitation can easily reach forces above 1000 MPa, 8 to 10 times greater than simple grinding can result.
