PHYSICAL PROCESS TECHNOLOGY The Physical Process Technology Department is involved in developing processes and process components based on physical and physical-chemical principles. Our customers are manufacturers of process components, contractors, and pro- cess system suppliers, and come from sectors such as metal processing, the food industry, biotechnology or the supply of drinking water. Current main themes Heat storage using thermo-chemical processes Use of sorption systems to remove moisture from gases, in particular from air to provide water Drying in a superheated steam atmosphere with integrat- ed recovery of volatile materials Recovery of inorganic nutrients Production of soil-improving substrates from organic residuals Electrolytic and photolytic water treatment Stabilization of foods using pressure change technology (PCT) P T technology for efficient cell disruption combined with extraction se of electric fields for selective substance separation Microwave technology for defined and fast energy charge Apart from our technical competence and specialized ex- pertise, a hallmark of the quality of our R&D activities is our focus on sustainability Thus, for e ample, we replace flows of raw materials by recycling in primary quality, upgrading or overhauling processes for the efficient use of regenerative energy and find ways to improve the efficiency of energy use This also leads to improved economic efficiency of processes, meaning that our approach satisfies both ecological and economic demands at the same time. One example of this is the development of a process of storing heat, which is, for example, provided as waste heat from the conversion of bio- gas into electricity. The intention is to be able to provide heat energy for industrial use at any time and, thanks to the high energy density, at any location; thus the supply is not directly linked to when and where the energy has been generated. Potential applications are drying processes in production, supplying heat to buildings, or the concentration or thicken- ing of highly contaminated process wastewater with vacuum vaporization. Our development work on processes and process components extends from initial laboratory-scale characterization and analytics via simulation and software modeling to design and system integration in industrial applications. For developing and designing our technical solutions, we have access to the latest 3D CAD design software, which is directly linked by data interface to various numerical simulation programs. We primarily use COMSOL Multiphysics® for the theoretical mod- eling of multi-phase processes such as the behavior of solid particles in a fluid flow, and T Microwave tudio® for the calculation of electromagnetic fields in cavities and the design of antennas to generate them in a defined way rom the data thus gained we can proceed to realize demonstration proto- types using the many resources at our disposal – workshops, laboratories and pilot plant facilities, as well as a network of industrial partners. The Physical Process Technology Department is staffed by sci- entists from various disciplines – such as process engineering, chemical engineering, food chemistry, mechanical and electri- cal engineering – who work together in multi-disciplinary 42 COMPETENCES
