20140923 SOPAT GmbH (DE) - Mr. Sebastian Maaβ – “On-line measurement of Droplet size in Emulsions and Dispersions”

Soppatec is a spin-off from the Institute of Chemical and Process Engiuneering TU Berlin, where the Smart Online Particle Analysis Technology SOPAT was developed after having screened a large number of existing methods and ranking these on specific features. SOPAT should overcome the drawbacks of all others. The SOPAT Focused Beam Reflectance Measurement FBRM is suitable for particles as well as droplets in liquids resulting in real time measurement with precision of 0,5μm using video techniques, stereomicroscope and image analysis. Validation of organic droplets (n-butylchloride, petroleum and toluene) in water with manual determination of Sauter mean diameter is excellent. The software allows visualization and process control. www.sopat.de


20140923 HeatMatrix BV – Mr. Bart van den BergMark - “Technoproject results: Waste heat recovery from corrosive flue gas”

The start-up company HeatMatrix developed a low fouling, light, corrosion and heat resistant plastic heat exchanger for gaseous waste streams: HMX. One step heat exchanger improves energy efficiency by 5%. It features a counter current matrix lay-out. In this NL GUTS supported validation project the HMX was tested in flue gases of around 160°C with ambient air cooling down to 100°C. Pressure drop was around 5,5 mbar, without loss of functionalities and integrity. In the second test cooling was with fouling process air. Process was stable but with fouling at process air side and 6 mbar drop. In situ cleaning was effective. Estimated payback time for recovering 50% of lost heat is 1,5 years. www.heatmatrixgroup.com


20140923 PRISNA B.V. – Mr. Karel Lund – “NADES: Extraction from the plant kingdom”

Prisna BV started as a spin-off from University Leiden and today specializes in extraction, isolation, purification and chemical analysis of biomass components for pharma (API), cosmetic and agro-industries with CPC, SCCO2, SFE, SFC technologies. Prisna developed NADES using Natural Deep Eutectic Solvents to selectively extract stable organic colorants from flower tops discarded as waste. The extraction process was elucidated and extract examples were presented. Market application is underway. www.prisna.nl


20140923 Austrian Institute of Technology (A) – Mr. Bernhard Gahleiter – “ChitoClean Enhanced Chitin-Based Biosorbents for Drinking Water Purification”

In an EU sponsored FP7 project the Health & Environment group of AIT coordinates an international consortium to develop the bio-sorbent ECM from Chitin through a chemical modification without the disadvantages of other Chitin based sorbents. The lab and pilot tests results are: Chitosan removes humic acid, colour and heavy metals. ECM seems to be safe for drinking water; domestic appliances prototype tested; large scale pilot with sand filter, Chitosan filter and polishing activated carbon operates well. Technique seems economically feasible. Next step is to develop sustainable EMS regeneration. www.ait.ac.at/departments/health-environment/


20140923 TU Eindhoven – Mr. Wim Gaakeer – “Micro Liquid-Liquid Extraction – Experimental Proof”

TU Eindhoven favors continuous micro-reactors because of capacity. It also enhances the potential of downstream unit operations like micro-separators. The micro L-L extractor capacity per m ³ unit volume is high. Advantages are fast mass transfer, good separation, of phases after the transfer and increased yield in counter current mode. Capacity increase done without scaling-up the process. Taylor flow conditions may have smaller kLa but extraction efficiency = 1 in only seconds residence time, while phase separation is easy with low energy dissipation. The theory behind Taylor flow separation was highlighted with design features and experimental proof. In addition to Taylor extraction, emulsion an coalescer of micro-channels with hydrophilic and hydrophobic walls is very efficient. www.tue.nl https://www.tue.nl/en/university/departments/chemical-engineering-and-chemistry/


20140923 IOI LodersCroklaan – Erik Schweizer - “Extraction of Spent Bleaching Earth”

IOI LodersCroklaan Rotterdam refines crude vegetable oils. One of the process steps is bleaching earth filtration. Spent bleaching earth is disposed of for fermentation and incineration. Total amount in NL is 50.000 ton/year, still containing 25% of vegetable oil with very valuable compounds to be recovered at highest purity. Theory and test results of different extraction methods were presented. They justify the development of a spent bleaching earth extraction plant that both recovers valuable compounds and produces extracted bleaching earth for reuse/recycle. http://europe.ioiloders.com
