The group “Process Engineering” deals with the production of SNG (substitute natural gas) through various process paths. The work includes three sections:
  • Generating and processing of biogas
    Biomass, moist and poor in lignin, can be converted by fermentative processes in biogas plants into raw biogas (main components: methane, carbon dioxide and other trace compounds). The group process engineering is concerned with both a novel fermentation process under pressure as well as different processing steps to transform the raw biogas into SNG.
  • Catalytic and biological methanation
    Another area of work includes the production of SNG by catalytic and biological methanation on the process chains; biomass gasification and power to gas. The focus is on new reactor concepts such as three-phase and the honeycomb-methanation, which are especially optimized for the requirements of the above-mentioned process chains. In this field, the process chains are evaluated economically and ecologically using system analysis.
  • Hydrodynamics in multiphase systems
    In some of the studied processes (biogas upgrading in absorption columns, biological methanation, three-phase-methanation), hydrodynamic effects as well as the mass transfer of the gaseous components play a crucial role in reactor output. These effects are systematically investigated in different systems in order to optimize the processes. The investigations include in the broader sense also solubility studies.
