20111207 MOMENTIVE – Anna Tihaya – “Separation scan executed at Momentive”

Momentive produces tertiary carboxylic acid resins in reactors after which the product is washed in a number of mixers and settlers in series. The scan was jointly executed by Acordio (Jan Dijk) and Biogonaal (John Krijgsman). Challenge was to improve product quality, reduce fouling and corrosion and reduce catalyst residuals. The scan experts took design, engineering and operation aspects into account to define short, mid and long term improvements. The added value of the scan was the systematic approach helping to understand the boundaries of the problem, recommendations for small investments measures with good results, recommendations that confirmed Momentive’s efforts and a change of mentality that a more practical hand on approach will work. www.momentive.com


20111207 MACT – Ton Franken – “Separation scan executed at Sappi Nijmegen”

Sappi Nijmegen uses waste paper as raw material. Pulping waste paper leads to release of dextrin in water, that later decomposes to undesirable fatty acids. As part of a KCPK project the separation scan investigates the feasibility to use nanofiltration to recover dextrin as well as paper fiber and water. MACT has executed the scan. The added value of the scan besides the technical feasibility was the pragmatic approach, triggering other potential improvements in Sappi’s production and a contribution to what paper and carton might do with valorizing residual streams. The economy did not meet the criterion of one year payback time, but gives enough food for further thoughts. www.sappi.com www.mact.nl


20111207 TNO – Arno Volker – “Ultrasonic Particle Monitor”

TNO Delft has developed an inline ultrasonic concentration and size distribution monitor (UPM) for particles and drops in liquids. It uses pulses of ultrasonic waves that are reflected by particles and collected by a receiver, all mounted in line on process piping. It is based on amplitude changes depending on properties, location and number of (more than one kind of) particles and applies forward model that always the strongest echo will be detected. Current practical application is already in oil exploration and production to discriminate between oil droplets and solid particles in water:0-100-1.000 ppm and 3-5-150 μm. It is insensitive to fouling, variations in salinity, pH, temperature,turbidity and chemical composition of the liquid and combines little maintenance with high availability. www.tno.nl


20111207 Elemetal – Bert-Jan Kuipers – “Recycling copper from waste to energy slag and ashes”

Elemetal is an SME and aims at up-cycling of metals, currently focusing on recovering metals from slag and ashes with primarily copper. After mechanical separation, slag and ashes undergo Cu selective leaching under specific conditions. Copper is extracted from the leach and the concentrated extract regenerated with an electrolyte from which the pure element Cu is recovered by electrolytic precipitation. Current status is demo with 8-10 ton bottom ash per cycle. 750 ton per cycle is under construction. The technical as well as the economical feasibility has been demonstrated. www.elemetal.eu


20111207 Progress Control – Dirk van Toledo – “Multispectral technology for a wide range of separations”

ProgressControl is an SME developing advanced measuring and control devices and advanced technologies for sustainable processes. The use of multispectral ‘light’ and high speed camera’s enables separation on basis of shape, color, density, humidity, surface properties and density. The quintessence is increase of contrast between objects, that with the normal eye or

with conventional spectral detectors cannot be distinguished.. An additional feature is the use of fluorescent surfaces. The technology is fast enabling the separation of continuous streams with large numbers of objects. Applications are found in sorting peanuts, nuts, biological products, mixtures of plastics, fungi. www.progresscontrol.com
