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.

Gasification of black liquor (BL), a byproduct from the pulp and paper industry, is a promising technology for production of renewable fuels and chemicals that has been attempted with a range of technology variations. A 3 MW th pilot plant for pressurized oxygenblown entrainedflow BL gasification (BLG), located in Piteå, Sweden, has accumulated >25 000 operating hours of which >8000 h with ...

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 Bäckhammar pilot plant is however not integrated into the host mill, and thus provides for significantly reduced synergies and 4 The black liquor is a type of a residue material obtained within a pulp mill production process in a form of an aqueous

Results: Since 2013 SunCoal develops a process for the separation and refinement of lignin from black liquor. After completing the first production campaigns in SunCoal's pilot plant in 2016 the engineering department started to identify technical problems and to optimize the entire process.

• The EMPYRO pyrolysis oil plant of BTG in the Netherlands and Fortum's plant in Joensuu in Finland are commercial biooil plants replacing fuel oil. • The CHEMREC BioDME project has been the first project to demonstrate the conversion of black liquor to biodimethylether. • NESTE, ENI, TOTAL UPM lead on hydrotreated oils/wastes

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.
