Status of the Swedish National Black Liquor Gasification (BLG) Development Program

摘要

A focused effort to bring high temperature black liquor gasification technology to market was started in 2004 when the Swedish government and industry joined forces to fund a national 3-year Black Liquor Gasification (BLG) Development Program. This paper reports on the status of both parts of the program, experience from the first year of operation in the pressurized oxygen blown 20 tds/day Chemrec high temperature black liquor gasification development plant DP-1 in Pitea, Sweden and a summary of the focused BLG research program aimed at closing identified knowledge gaps before scale-up and commercialization. An outlook of the planned continuation of DP-1 operations and R&D activities during the three year period 2007-2009 is presented, as are plans shared for scale-up of the technology to commercial demonstration for production of renewable motor fuels at Swedish pulp mills.
