Institute of Chemical Engineering page 2 Achema 2012 Thermal Process Engineering SHOCOTEC The project Funded by Austrian national grant (FFG) Duration: 24 months Started in January 2012 Partners: Institute of Chemical Technologies and Analytics, TU Vienna Axiom Angewandte Prozesstechnik GmbH QuantaRed Technologies GmbH
Institute of Chemical Engineering page 3 Achema 2012 Thermal Process Engineering SHOCOTEC 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
Institute of Chemical Engineering page 4 Achema 2012 Thermal Process Engineering SHOCOTEC compression cooling (drying) reheating raw gas H 2 S scrubbing adsorption: removal of TOC, tar, … adsorption: removal residual H 2 S gaspermeation: CO 2 separation product gas biomethane (CH 4 rich) offgas (CO 2 rich) chemicals effluent 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 H 2 S-contents in raw gas or if high fluctuations in gas quality or quantity are to be expected
