About 40 TWh black liquor produces yearly at the Swedish paper mills. Pressurised black liquor gasification is an alternative technique that in the long run can be able to replace the conventional recovery boiler process with an increasing electricity production of about 1000 MW as consequence.
An alternative is to produce bio based fuels that should correspond almost 30% of total demands of transportation fuels in Sweden. The project contains of Computational Fluid Dynamics modelling of the reactor, quench cooler and counter current condenser in the gasifier together with experimental measurement in Chemrec’s DP-1 pilot gasifier. The goal with the work is to offer modelling and simulating tools that support the scale up of the gasifier to full scale for commercial use.
