Due to several advantages the importance of biogas production as part of the renewable energy technology spectrum has been increasing steadily for the last years. In contrast to other renewable energy sources like wind or solar biogas can be stored and transported very easily. For an efficient use of these potentials, biogas has to be fed into the already existing natural gas grid. In fact, this requires a certain quality of the biogas (e.g. in terms of maximum allowable water, sulfur dioxide and carbon dioxide concentrations) being equal to the natural gas standard. That’s why biogas upgrading is a key technology for its storage and transport and therefore for a sustainable green energy policy.
Main fields of research
Bases on this simple adsorption/desorption mechanism more complex fine drying regimes are tested using coupled mass-heat flow and selective radio wave heating effects. The goal of these more complex investigations is a continuously working fine drying process with only one packed bed. This optimization can further reduce energy consumption during the regeneration step. Studies focusing on adsorber materials and process engineering finally complete the research activities in this field.
