Topic

BGA-IL deals with the development of an upgrading process for raw biogas, applying task specific ionic liquids for intensification of the biogas purification process. The consortium consists of the DVGW research center at EBI, IoLiTec GmbH, an expert for ionic liquids and Powerfarm Holding GmbH, a specialist for construction and operation of biogas plants. The work scope of the project contains experimental work in lab as well as a field test at an upgrading plant of a participating project partner for demonstration purpose. The experimental results will allow for a direct comparison of the ionic liquids-based process with state-of-the-art upgrading technology. Thus, the potentials of the new upgrading process can be evaluated under realistic conditions.

Aims

The project focusses on increasing energy efficiency and reducing operating costs of biogas upgrading in comparison to state-of-the-art technologies. These targets shall be reached by developing and introducing task specific ionic liquids for biogas upgrading, simplifying process technology and adapting operating parameters of the purification process in order to gain benefits out of the special physical and chemical properties of the applied liquids.

Measures

Appropriate ionic liquids for application in the biogas upgrading process will be developed and characterized in close cooperation between the project partners. Relevant physical and chemical data will then be determined experimentally and implemented into the process modelling tool, which provides a basis for optimization of mechanical configuration as well as operating parameters. The most promising liquids will then be applied into the existing lab scale upgrading plant and tested with model gas mixtures as well as in field and finally assessed regarding realization of energetic and economic improvements in the biogas upgrading process.
