liquor) forming pulp and the byproduct black liquor. The pulp is used to produce paper and the energy and chemicals in the black liquor are recovered. The energy efficiency of a pulp mill could significantly increase if the current combustion based energy recovery system was replaced by a black liquor gasification system.

In this study, the impact of black liquor shocks on multiple stage biological treatment plant was studied. The tests were carried out in a lab scale plant and using a mathematical simulation model. The results showed good relation to a parallel situation at the Gruvön Mill. The MultiBio concept is persistent to shortterm black liquor spills due to the design where the black liquor is diluted ...

The main hypothesis in this study therefore is that ultrafiltration could be used effectively as a technique to extract lignin from black liquor generated from South African Kraft mill black liquor. In addition, simulations can be performed to elucidate the fouling mechanism by which the flux decline experimental data conforms to.

The pilot plant is financed by a government grant of SEK 71 million (approx. € 7,5 million) from the Swedish Energy Agency. The grant finances the development of, and testing in the pilot plant to produce Lignol from lignin, extracted from black liquor, as well as the development of RenFuels patented method of membrane filtering.
