Biorefineries efisien melalui Intensifikasi Proses Ultrasonik


Ultrasonication is a process intensifying technique, which is implemented into various processes in biorefineries. Typical processes that benefit significantly from ultrasonic treatment are extraction, slow heterogeneous reactions as well as other applications that involve intense mixing, homogeniaztion and dispersing. Ultrasonication accelerates processes and reactions and makes them more efficient. Results of ultrasonically-promoted processes are higher yields/outputs and higher conversion rates.

What are Bio-Refineries?

A biorefinery is a production facility that integrates biomass conversion processes and processing equipment to produce fuels, energy and other beneficial products such as chemicals from the biomass raw material. Typical biomass processed in biorefineries include raw materials such as agricultural waste and by-products, which is up-cycled into various value-added, bio-based products, e.g., food, feed, chemicals, bioenergy (biofuels, power and/or heat). The production processes of a biorefinery are intended to be sustainable and environmental-friendly. Similar to conventional refineries, biorefineries can provide multiple chemicals by fractioning an initial raw material (biomass) into multiple intermediates (carbohydrates, proteins, triglycerides) that can be further converted into value-added products. A key characteristic of biorefineries is valorization and recycling/upcycling of waste such as agricultural, urban, and industrial waste by the means of converting useless biomass into valuable materials.

Ultrasonically Intensified Biorefineries

By the integration of ultrasonication, many processes such as extraction, digestion, disintegration, transesterification amongst many others can be run significantly more efficient. Ultrasonic process intensification in a biorefinery aims mainly to improve yields, to make processes more time- and energy-efficient and to enhance the purity and quality of the final product. Ultrasonication can contribute to various biorefinery processes.

How Does Sonication Work?The Working Principle of Ultrasound

kavitasi ultrasonik kuatFor high-performance ultrasonic processing, high-intensity, low-frequency ultrasound is generated by an ultrasound generator and transmitted via an ultrasonic probe (sonotrode into a liquid. High-power ultrasound is considered ultrasound in the range of 16-30kHz. The ultrasound probe expands and contracts e.g., at 20kHz, thereby transmitting respectively 20,000 vibrations per second into the medium. When the ultrasonic waves travel through the liquid, alternating high-pressure (compression) / low-pressure (rarefaction or expansion) cycles create minute vacuum bubbles or cavities, which grow over several pressure cycles. During the compression phase of the liquid and bubbles, the pressure is positive, while the rarefaction phase produces a vacuum (negative pressure.) During the compression-expansion cycles, the cavities in the liquid grow until they reach a size, at which they cannot absorb more energy. At this point, they implode violently. The implosion of those cavities results in various highly energetic effects, which are known as the phenomenon of acoustic / ultrasonic cavitation. Acoustic cavitation is characterized by manifold highly energetic effects, which impact liquids, solid/liquid systems as well as gas/liquid systems. The energy-dense zone or cavitational zone is known as so-called hot-spot zone, which is most energy-dense in the close vicinity of the ultrasonic probe and declines with increasing distance from the sonotrode. The picture left shows intense cavitation at an 1kW ultrasonic probe in water. The main characteristics of ultrasonic cavitation include locally occurring very high temperatures and pressures and respective differentials, turbulences, and liquid streaming. During the implosion of ultrasonic cavities in ultrasonic hot-spots, temperatures of up to 5000 Kelvin, pressures of up to 200 atmospheres and liquid jets with up to 1000km/h can be measured. These outstanding energy-intense conditions contribute to sonomechanical and sonochemical effects that intensify biomass and chemical systems in various ways.
The main impact of ultarsonication on biomass result from the following effects:

  • Geser tinggi: Gaya geser tinggi ultrasonik mengganggu cairan dan sistem padat cairan yang menyebabkan agitasi intens, homogenisasi dan perpindahan massa.
  • Dampak: Liquid jets and streaming generated by ultrasonic cavitation accelerate solids in liquids, which leads subsequently to interparticluar collision. When particles collide at very high speeds, they erode, shatter and get milled and dispersed finely, often down to nano-size. For biological matter such as plant tissue and bio-waste, the high velocity liquid jets and alternating pressure cycles disrupt the cell walls and release the intracellular material. This results in highly efficient extraction of bioactive compounds and the homogeneous mixing of biomass.
  • Agitasi: Ultrasonication menyebabkan turbulensi intens, kekuatan geser dan mikro-gerakan dalam cairan atau bubur. Dengan demikian, sonikasi selalu mengintensifkan perpindahan massa dan mempercepat reaksi dan proses dengan demikian.
