    Titel: Valorisatie van restwarmte uit exotherm proces met stoomcompressie.

    Spreker: Paul Straatman, Development Engineer, Indorama

    Abstract: Grote hoeveelheden restwarmte uit een exotherm proces worden meestal niet meer gebruikt. Dit is vanwege het temperatuurniveau dat vaak te laag is om andere processen aan te drijven. Met deze restwarmte kan wel water verdampt worden zodat stoom van lage druk verkregen wordt. Deze stoom kan vervolgens worden gecomprimeerd naar druk niveaus die in de fabriek worden gehanteerd. Er is elektriciteit nodig om de compressor aan te drijven, echter de meeste energie om de stoom te maken is al geleverd als gratis latente (verdampings) warmte. Door stoom met MVR op te wekken kan op aardgas en CO2 emissie worden bespaard.

    - Waarom en hoeveel is mvr beter dan een e boiler?
    - Waarom is dit niet vaker toegepast en wat is er nieuw aan?
    - Wat is het potentieel voor uw fabriek?

    Titel: Using CO2 as feedstock to produce monomers for interesting classes of polyesters.

    Spreker: Gert-Jan Gruter, CTO @ Avantium, Amsterdam, the Netherlands
    Professor Industrial Sustainable Chemistry @ University of Amsterdam

    The combination of the predicted polymer market growth and the emergence of renewable feedstocks creates a fantastic opportunity for sustainable polymers. To replace fossil-based feedstock, there are only
    three alternative sustainable carbon sources: biomass, CO2, and existing plastics (via mechanical and/or chemical recycling). The ultimate circular feedstock would be CO2: it can be electrochemically reduced to formic acid derivatives that subsequently can be converted into useful monomers such as oxalic and glycolic acid.
    This presentation will focus on why from CO2 as a feedstock, some chemicals (monomers) have much more techno-economical potential than others. We will discuss why the transition to new feedstocks (biomass and CO2) will almost certainly also lead to a transition of materials we will use in the future (from polyolefins to polycondensates (polyesters)). It will also be discussed why this is not a threat but an opportunity.

    Gert-Jan Gruter(1963) has a background in Polyolefin catalysis (DSM 1993-2000; now Sabic) and has been Professor of Polymer Catalysis at Eindhoven University of Technology.

    After joining Avantium in 2000, he was appointed as Chief Technology Officer (CTO) in 2004. He initiated the YXY/Synvina technology, which includes novel processes from carbohydrates to FDCA monomer and 100% bio-based PEF polyester for bottles, fibers and film. In addition, Gruter is involved in the development of the “DAWN Biorefinery Technology” for the production of pure glucose from agro and forestry lignocellulosic residues, the “RAY MEG Technology” for the 1-step hydrogenolysis of sugars to Mono Ethylene Glycol and the “Volta Technology” for the electrochemical reduction of CO2 to polyester monomers such as oxalic acid and glycolic acid.

    Gert-Jan is inventor on more than 100 patent applications; he was elected “2014 European CTO of the year” and runner-up European inventor of the year in 2017. Gert-Jan is currently part-time professor Industrial Sustainable Chemistry at the University of Amsterdam (UvA), where he is working on novel sustainable polyesters for re-use, on biodegradable polyesters, on chemical recycling and upcycling, on consumer psychology and on ocean plastics.
