Think Bigger, Engineer Smaller – Highlights from the Symposium
I went to the Process Intensification Symposium ‘Think Bigger: Engineer Smaller’, in Groningen on May 19th 2016.
Here are my highlights of this symposium:
Professor R. Lammertink of University Twente showed how membrane mass transfer can be increased by 30 % by adding a very thin polymer layer with pillars to the membrane.
Professor S. Kersten of University Twente showed that lignocellulose biomass can be converted into a liquid with a yield of 90 % by using the liquid product as a solvent in the process. Little char is formed and the oxygen content is reduced by 50 %.
Ir W. Stam of Flowid showed the essentials of the Spin-Pro reactor: High G/L mass transfer, staged countercurrent flow and heat removal. Flowid now offers not only commercial scale reactors but also down-scaled reactors for laboratory testing.
Professor J. de Wilde of University Louvain-la-Neuve, Belgium, showed the working principle and applications of a Vortex Chamber Fluid Bed. Tangential gas inlets cause the solids to rotate and form a uniform fluid bed, due to the high-g forces. Because of the uniform gas/solids contact this device proved to be very effective for uniform particle coating and spray drying of milk. The test facility has a diameter of 0.6 m, which is sufficient for large commercial scale applications. Scale-up knowledge is furthermore supported by CFD models.
