Key facts
Develop a novel process for the desulphurisation of renewable gaseous energy carriers
Focus: biogas and producer gas from wood steam gasification
Based on already developed technology of chemical-oxidative scrubbing
Enhancement of process intensification, separation selectivity and plant economics
Development and application of advanced laser-spectroscopic analysis methods

Example: simplified flowsheet of biogas upgrading plant for the production of biomethane to be injected to the natural gas grid
Raw gas desulphurisation is integral part of gas upgrading Especially crucial at elevated H2S-contents in raw gas or if high fluctuations
in gas quality or quantity are to be expected
