20160419 Wageningen UR – Mr. Jaap Dijkshoorn; Maarten Schutyser – “Deterministic Ratcheting for Fractionation of Suspensions”

The Food Process Engineering Group at WUR has developed ratcheting to a workable process for separating more or less rigid suspended particles. In ratcheting particles with a smaller diameter follow the liquid flow around the obstacles while larger ones move away from it. The solids density is similar to that of the liquid. The suspension has to stay below a concentration where particles interact and Reynolds should be in the laminar regime, where higher flowrates improve separation. 35 µm can be separated from 105 µm. Target is 5 µm. . Pressure drop distribution is critical. Design rules need to be derived with focus on large scale application. Bench scale design is underway. The use of sieves (Veco) mimicking obstacles leads to higher capacities. www.wur.nl


20160419 Brilliant Water Systems B.V. – Mr. Michiel Arnoldy - “Twinzapp”

BWS developed the Twinzapp technology, today marketed and manufactured in cooperation with Parker. Originally installed for de-oiling produced water from oil and gas wells containing a multitude of surfactants, BWS seeks new applications. Twinzapp has two configurations Electro-oxidation and Electro Coagulation with Fe or Al sacrifice electrodes and Electro Oxidation with inert Ti or Carbon electrodes. With EC metal ions are dissolved in the water to form hydroxide flocs that trap emulsified or suspended material to be separated by gravity. In the latter OCl- is generated that attacks the charged layer around the emulsion droplets resulting in coalescence followed by flotation. The Twinzapp has wireless sensors, oil in water analysis, advanced power control to reduce power consumption, non-fouling through polarity reversal and is ATEX certified. Installed capacities up to 60 m³/h single unit. www.brilliantwatersolutions.com


20160419 Russell Finex N.V. – Mr. Robert-Jan Zoeteman – “New developments in ultrasonic screening”

Russell Finex (USA) with its Benelux company in Mechelen (BE) manufactures screens, sieves and filters for a vast number of applications in almost all sectors of process industry in 140 countries. Latest topic is 3D printing. Specialty is low noise vibrating screens, easy to strip and clean, quick replacement and high throughput per m². In Belgium RF operates a fully equipped test lab. Screens for solids range from 20 µm up with capacities up to 70.000 kg/h. As a stack they fractionate up to five grades. With a second layer in the overflow the screen area is enlarged by 70%. To prevent any loss of powder or dust the outlets of te screens can be sealed by a intermittently opening gated outlet. Screens can be completely enclosed in food and pharma-grade versions. For more demanding applications as regards plugging of screens, RF has developed for small and large screens an ultra sound probe directly applied on the screen wires mesh, that efficiently prevents the materials to stick on the wires. It also increases the capacity in non-sticky applications considerably. www.russellfinex.com 


20160419 Albemarle Catalyst Company BV - Mrs. Yvette Veninga - “Separation Processes at Albemarle”

Strongly knowledge and innovation driven with > 3.500 patents and > 100 PhD’s Albemarle’s turnover is 3,3 bio USD/year producing in four business units (Refining, Lithium and advanced materials, Bromine specialties, Surface treatment) with 6.900 personnel spread over 100 countries. The Amsterdam site produces catalysts for a number of applications with a large section for FCC, HPC in mineral oil refining, including SOx NOx abatement, and chemical processes. Besides production Albemarle provides engineering support and other services to clients in process optimisation. Basic materials are Aluminium-oxides and Zeolites in different forms, grades and activities. The properties of catalyst particles on reactivity, selectivity, entrapment and mechanical features were highlighted with the different production steps such as precipitation, crystallisation, purification, rotating drums, vacuum belts, cartridge filters and material recovery. The units were demonstrated during a guided tour in the factory. www.albemarle.com/


20160419 Phytonext B.V. – Mr. Eral Osmanoglou – “Mild Extraction in a one step process”

The start-up Phytonext is a spin-out of TOP-bv for the extraction and production of valuables from plant material. They focus on mild conditions during their Phytosol extraction process with safe non-toxic solvents in order to maintain the original features of the extracted components and avoid any damage to the molecules. Phytonext has several technologies available to enhance extraction among which PEF Pulsed Electrical Field (see also TOP-bv presentation on 2012 09 18 of NL GUTS Technoproject on PEF) Focus is niche markets for natural compounds, herbal medicines and bio-active ingredients. In order to overcome the valley of death Phytonext moved from a developer & supplier of technologies to an extractor of compounds using its proprietary technologies. Several pigments and flavours were passed on through the audience. www.phytonext.nl


20160419 TU Dortmund - Mr. Matthias Wierschem - Ultrasound-Assisted Enzymaticlly Catalysed Transesterification for Reactive Distillation Processes

The faculty of Bio- and Chemical Engineering of the TU Dortmund develops this US-ERD process with very selective enzymes immobilised in porous beads or as coating on structured packing moving from batch to continuous aiming at much higher reaction velocity and less by-products. With enzymes singe enantiomers are produced. The ultrasound transducers increase investment considerably, but US enables faster reaction, reducing equipment sizes which neutralises the extra investment. The RD concept shifts the reaction to the right. The ERD process model coincides well with experimental values. The concept is feasible. www.th.bci.tu-dortmund.de
