Ultrasound-assisted emerging technologies for chemical processes

The chemical industry has witnessed many important developments during past decades largely enabled by process intensification techniques. Some of them are already proven at commercial scale (e.g. reactive distillation) while others (e.g. ultrasound-assisted extraction/crystallization/reaction) are on their way to becoming the next-generation technologies. This article focuses on the advances of ultrasound (US)-assisted technologies that could lead in the near future to significant improvements in commercial activities. The aim is to provide an authoritative discussion on US-assisted technologies that are currently emerging from the research environment into the chemical industry, as well as give an overview of the current state-of-the-art applications of US in chemical processing (e.g. enzymatic reactive distillation, crystallization of API). Sufficient information is included to allow the assessment of US-assisted technologies and the challenges for implementation, as well as their potential for commercial applications
