Value from gas streams

Upgrading of industrial gas streams

​Some industrial gas streams contain valuable compounds that are disregarded for utilization. These gas streams can be waste gas, side stream or product gas with impurities.  Furthermore, CO2 emissions can be a concern.

VTT can analyse your industrial gas stream and design the full process from your gas stream to the valuable product. For this, we do process, reactor and catalyst development. We can do experiments from lab to pilot scale.

By recovering your industrial gas, you create value added products and increase your revenue. You can also replace your fossil based raw materials which reduces your CO2 emissions.

Gas cleaning

  • Syngas reforming
  • Particulate filtration
  • Acid gas removal, eg. H2S, CO2. Selectively or non-selectively
  • Organic sulfur removal
  • HCN/NH3 removal
  • Heavy metals removal
  • Ultracleaning, eg. deep desulfurization. Knowledge in ultraclean gas purification for synthesis applications

 

CO2 emission to valuable products

    • Production of liquid and solid hydrocarbons
    • Production of synthetic natural gas

 

Syngas to valuable products

  • Production of liquid and solid hydrocarbons
  • Production of synthetic natural gas

Challenge: Valorisation of industrial CO2 emissions to chemicals.

Solution: Demonstration of Fischer-Tropsch synthesis with real side stream gases by mobile synthesis unit .

Benefit: Changing CO2 emissions to valuable products.

 

Challenge:  To create know-how in production of fuels and chemicals from CO2 emissions which are the key technologies for CO2 utilization and how do they work?

Solution: Production of synthetic natural gas, diesel, gasoline, wax and methanol using CO2 as the carbon source.

Benefit: To create valuable products and to reduce dependency on fossil fuels.

 

Challenge: To demonstrate a bench-scale biomass-based gasification gas ultracleaning process.

Solution: The process is designed to remove sulphur-, nitrogen- and residual tar- impurities down to levels suitable for synthesis applications without expensive scrubbing process-steps.

Benefit: The purified gas will be synthesized into Fischer-Tropsch hydrocarbons. The gas cleaning step is crucial in enabling economical biomass-to-liquids or -gas and other dirty gas utilization processes.

 

Challenge: Stream of hydrogen regarded as low value side product with several impurities or contaminants. Limited end usage possibilities for by-product hydrogen due to trace impurities.

Solution: With integration of new technology to existing infrastructure you can utilize low value hydrogen streams for value added products, such as, vehicle fuel and chemicals.

Benefit: VTT can thrust your business towards sustainability and create value from existing by-products.
