Energy Efficient Processes

Intensification of thermal processes via development of novel energy efficient power systems, engines, reactors and processes is the main subject of this research line. The focus is placed on multicomponent and multiphase flows, liquid atomization, droplets evaporation and drying, combustion, supercritical fluids, heat transfer and fluid dynamics. Renewable methods and transition to the future technologies are of prime interest. 

example research

  • HERMES - Highly Efficient Super Critical Zero Emission Energy System

    Wind and sun will be central energy sources of a climate neutral Europe 2050, bringing with them the need to balance weather dependent differences between supply and load. Conventional gas turbines can fulfill this task also for longer periods even well as they can stabilize the grid with their capability of quick start/stop. However, their efficiency is limited and – even if burning climate neutral hydrocarbons – they still produce local emissions.

  • BALANS - Renewable Heat And Power From Non-Woody Biomass

    The application of woody biomass for power and heat generation may not always be justified or economical feasible, also because the biomass could be use as a feedstock for production of high-end products. Instead, for regular power and heat production, a biomass of non-woody origin or sewage sludge could be used. However, combustion of such fuels brings a major challenges related to their complex and varied composition, water content and seasonal availability. In this project, these challenges are addressed by means of full scale operation of bio-energy station. The reduce the uncertainty regarding the combustion process, numerical models able to mimic the fuel complexity will be employed to study the non-woody biomass on a grate.

  • TORWASH - Design And Optimization Of A Hydrothermal Process To Convert Organic Residues Into A Fuel

    In this project, a novel process developed and patented by the Torwash company, to convert wet organic residues into a solid feedstock for heat and power generation or production of biochemicals, is investigated numerically and optimized. The process is performed under elevated temperature and pressure, and the water is used as a reaction medium for the hydrolysis to separate solid and liquid fractions. By processing and reusing the liquid fraction to cover the energy demands of the process, a zero-waste energy neutral technology is achieved.

  • ENGENDER - Pilot Plant For The Next Step In Low Energy Drying Of Food And Other High Value Products

    The ENGENDER project aims to realize a breakthrough in drying of food ingredient materials using a new compact drying technology based on the Radial Multizone Dryer (RMD). In the project the RMD technology will be developed at the pilot-scale and design rules for industrial demonstration will be described. The expected energy savings are estimated up to 30% compared to conventional spray drying and will be confirmed for a selected set of model systems, that is, test materials.

  • RECOWATDIG - Sustainable Technology For The Staged Recovery Of An Agricultural Water From High Moisture Fermentation Products

    Sustainable development goals demand highest possible sustainability of the human activities. RECOWATDIG addresses this by research and development, aimed at obtaining a technical design of an installation for the staged recovery of currently neglected, agricultural water from drying of high moisture solid fermentation products. A high synergy is obtained by integration of water recovery, drying, hydrothermal carbonization and water purification with optimized use of the electricity and water storage, making the proposed technology “smart grid ready”.
