The PSA (Pressure Swing Absorption) unit has successfully been installed at the Steelanol plant. The modelling and engineering of the PSA is an important activity of the Carbon2Value project. The goal of the PSA is to treat the gas captured from the blast furnace, in order to inject an CO-rich gas stream into the ethanol fermentation reactors.

In the picture the gas compressor (bottom) and 8 PSA vessels (top) are shown, integrated in the Steelanol plant.
