Our process

  • The different feedstock comes from storage and is heated to 65°C, mixed with methanol and sodium methylate,and sent through the ultrasonic reactor.
    During this very short contact time (approximately 5 seconds),an instantaneous conversion of raw materials takes place.
    The mix is then sent through a settler to separate the Biodiesel (light phase) from the Glycerol (heavy phase).
    The light phase is then heated, and sent through a flash evaporator, to remove methanol and any present water.
    The almost finished biodiesel is then sent through a lead‐lag system of ion exchange resins towers, to remove any traces of glycerol and other contaminants.
    Finished biodiesel can then be sent to storage or distillation.
    The heavy phase is heated to 120°C, and sent through a flash evaporator, to recover methanol.
    The crude glycerol is then sent to storage, or to purification at later stage.

Ultrasonic Reactors

  • When sonicating liquids at high intensities, the sound waves that propagate into the liquid media result in alternating high‐pressure (compression) and low‐pressure (rarefaction) cycles, with rates depending on the frequency.
    During the low‐pressure cycle, high‐intensity ultrasonic waves create small vacuum bubbles or voids in the liquid. When the bubbles attain a volume at which they can no longer absorb energy, they collapse violently during a high‐pressure cycle.
    This phenomenon is called cavitation. During the implosion very high temperatures (approx. 5,000K) and pressures (approx. 2,000atm) are reached locally. The implosion of the cavitation bubble also results in liquid jets of up to 280m/s velocity.
    Ultrasound has been proven to generate very homogenous emulsions by the high cavitational shear. As the parameters of ultra sonication are fine‐tuned, particle size and distribution is well adjustable and repeatable.

Advantages of our Ultrasonic Biodiesel Reactors

  • Feedstock flexibility ‐ ultrasounds achieve the same great results with any feedstock, both high and low FFA feedstock can be used, including blends of different feedstock.
    Low power consumption ‐ with a total consumption of approximately 2kWh per ton of Biodiesel produced, our reactors are unmatched for economy.
    No moving parts ‐ ultrasonic reactors have no moving parts, meaning that there is virtually no maintenance required, apart from regular cleaning operations.
    Consistently High Yields and Quality ‐ by creating micro bubbles, that contract and expand increasingthe surface area where the reaction takes place instantaneously, molecular cavitation emulsifies the feedstock and reagents guaranteeing maximum yields and high quality Biodiesel at all times.
    Small plant footprint – due to their energy efficiency, the system has a capacity identical to highly energy intensive mechanical reactors, which are much larger and require a lot more retention time for the reaction to occur.
