High-gravity process intensification technology and application

Process intensification has long been known to be a vital concept and is considered to be one of the fundamental pillars of the chemical engineering domain. This paper reviews the advances on the high-gravity (Higee) technology, including the theoretical studies on liquid flow, gas–liquid mass transfer, residence time distribution and micromixing, and the applications of Higee technology in absorption, stripping, nanoparticles preparation and other fields such as sulfonation, polymerization, synthesis of diphenyl-methane-diisocyanate and emulsification. The application of Higee in industry shows good adaptabilities of this technology and brings considerable profits.
