Gas Conditioning Technologies for Biomass and Waste Gasification

During the past three years an intensive R&D&D has led to the successful design and scaleup of a wet scrubbing system which is now part of the BIOSYN biomall and waste gasification technology. The results have been incorporated in the basic design of two small units (capacity of 3.5 tn/h) to be built within the next two years for specific applications: urban wood and bartk residues. The producergas in these two units will be scrubbed and used in boilers or diesel units integrating power and heat generation. Fundamental work at the Universite de Sherbrooke has led to the formulation of a robust catalyst aimed at refurming crude producer gas containing tar. The interest of using 'clean' hot producer gas as fuel in gas or steam turbines has motivated further development: a two year'seffort has begun to design and scale up a hot gas conditioning module (filtration+catalytic reforming). The scaleup is being done at the BIOSYN pilot plant (nominal capacity of 50 kg/h) located in Sherbrooke.
