20150414 ECN - Mrs. Sigrid Bollwerk –“Anticipating a rapidly changing Energy Market: opportunities for industry”

ECN executed several policy and strategic energy studies with different scenario’s. From 1) a historical perspective of moving to more diversified energy supply, but still largely fossil and with a decreasing own production, and 2) the tendency that industry, energy and water infrastructures become integrated and more local and have to take consumer attitude into account, energy efficiency EE is becoming increasingly important for industry. Still most EE potential is untapped. ECN envisages a combination of circular and bio-based economies with a major contribution of renewable energy sources for heat, new process routes and products together with smart energy demand management and supply via multiple grids. www.ecn.nl


20150414 AkzoNobel – Mr. Riaan Schmuhl - “AIM to Innovate”

AkzoNobel developed the Auto Innovation Method AIM together with Traxxys. It enabled setting RD&I and technology strategy for short and long term chemical business. AIM is a structured way to improve productivity of chemical processes. Instead of starting at the lab for innovation, major feature of AIM is start at the process plant, identify alternative driving forces and translate these into new functions, process and equipment. Operations is added as key company participant, while the development process is facilitated by an external process/PI specialist. AIM is adopted a tool for ideation from positive feedback of case owners and participants as an efficient methodology, embedded in the innovation practices. Examples were given of reduced capital and operational cost, PI, small scale plants. www.akzonobel.com


20150414 Technical University Eindhoven-Mrs. Laura Kollau-“Biomass fractionation using Deep Eutectic Solvents”

TUe develops a process to recover or remove compounds from biomass with Deep Eutectic Solvents DES, mixtures of compounds that individually are solid and as mixture are liquid with a very low melting point and act as a solvent. The individual compounds have at least one hydrogen bond donor and one hydrogen bond acceptor. They are natural and exhibit features of ionic liquids, but have beneficial properties: easy and cheap, water and biocompatible, biodegradable. This unique feature is used to extract lignin from cellulose rich biomass. The lignin containing DES is separated from biomass by centrifuges. Adding water to the centrate precipitates the lignin. The biomass is washed with water and filtered giving a cellulose pulp. DES can be recovered for reuse after adding a biodegradable anti-solvent. The lab results are positive. Pilots are planned. https://www.tue.nl/universiteit/faculteiten/scheikundige-technologie/onderzoek/onderzoeksgroepen/chemical-and-process-technology/separation-technology/


20150414 Biovalor Europe BV- Mr. Jochem Görtzen- “Pulverising Air Dryer”

The SME Biovalor licenses the Pulverising Air Dryer PAD technology to install turnkey solutions in cooperation with EU partners. PAD has been tested on many feedstocks. Several commercial units have been installed. Feedstock with 20-50% dry solids is intensely mixed with a large volume of conditioned compression heated by the blower to pass several cyclones in series. In between cyclones auxiliary air can be injected. The mechanical forces in the cyclones add to separate water from the biomass reducing energy consumption. The total primary energy consumption is about 2.400 kJ/kg water evaporated, far below other technologies, saving about 50% on cost. Air emissions and discharged water load are low. Installation diagram and details were presented. Nominal capacity is 35.000 ton/year. www.biovalor-europe.com


20150414 Bronkhorst Hightech B.V. – Mr. Wybren Jouwsma – “Meaning of flow chemistry for chemical industry”

Manufacturer of precision mass flow meters Bronkhorst dedicates special focus on the NL supply chain of micro- and mini-reactor and separation systems as most promising technologies for future chemical plants being faster, cheaper and safer. These plants will have in-line measuring, analysis and control devices. Examples of applications were presented. Bonkhorst develops from metering devices to system solutions for modular production technology that features investment flexibility, capex and opex reduction, fast time to market, reduced energy and solvent consumption, smaller footprint and less transport by local production sites. www.bronkhorst.com


20150414 SolSep BV – Mr. Petrus Cuperus – “Technoproject results: Nanofiltration of viscous liquids”

SRNF is already practice for a number of applications. However leading spiral wound SRNF supplier SolSep has tested the application on viscous liquids in a NL GUTS sponsored Technoproject and presents the results for concentrating PPO in toluene while recovering toluene for NL GUTS member SABIC-IP. The retention of PPO is 100%, but with a bit of decolourisation from oligomers. Starting with PPO 10% wt the membrane flux decreases by the increasing viscosity or PPO content, but is in control. Critical are maintaining temperature for viscosity, cross flow for turbulence and spacer design. The osmotic pressure has little impact. Concentration up to 30% PPO is possible.NF is an alternative for production increase. www.solsep.com


20150414 Wageningen University – Mr. Ton van Boxtel - “Energy efficient drying with adsorbents, a PSE application”

WUR gives a nice example of Process Systems Engineering PSE to arrive at an energy efficient drying configuration. Starting from life phase aspects for dried products, looking at functionalities of drying for bio-products and as condition heat recovery WUR defines a two stage drying system with humidity adsorbent for drying air specific per stage (1 zeolite; 2 silica), adsorbent regeneration and (pinch) integrated heat recovery, that consumes 1345 kJ/kg evaporated water compared to 4330 kJ/kg for a conventional dryer. Optimisation diagrams were elucidated.
