Ultrasonic Reactor for Biodiesel Production

Hielscher offers ultrasonic mixing reactors for the production of biodiesel at any scale. The ultrasonic mixing improves mass transfer and reaction kinetics leading to faster transesterification and higher yield. It saves excess methanol and catalyst.

Ultrasonic reactors are recommended for production capacities of 0.25ton (80 gal) per hour or more. Hielscher offers ultrasonic reactors of an individual capacity of up to 16ton/hr (5100 gal/hr). In general you should consider using three to five units in parallel to accommodate variations in production rates.

Lower Material Costs and Boost Biodiesel Yield

Ultrasonic emulsification uses cavitational shear of ultrasonic homogenizersExcess methanol and catalyst are significant cost factors in biodiesel production. Hielscher ultrasonic reactors add cavitational shear to the mixing process. This gives you much smaller methanol droplets resulting in improved methanol and catalyst utilization. Therefore, less methanol and catalyst are required. In addition to that, the cavitation influences the reaction kinetics, leading to faster and more complete transesterification.

Inline Ultrasonic Mixing of Oil and Methanol

Flow-Chart of Continuous Biodiesel Processing Plant - Ultrasonic equipment integration to improve biodiesel technology.Ultrasonic mixing reactors replace tank agitators and other dynamic shear mixers. The ultrasonic reactors are generally installed to mix two feed streams. Oil and methanol (with catalyst). For this, a crude pre-mix is pumped into the ultrasonic reactor, where the ultrasonic cavitation mixes and emulsifies both reagents within 5 to 15 seconds. This is an inline mixing process. When the mix exits the flow cell reactor, the glycerin will separate by gravity within less than 60 minutes. Alternatively, you can feed the mix into a centrifuge after several minutes of residence / reaction time. The inline mixing reduces the number and volume of tanks used for conventional batch processing. This improves capital utilization.
