Emåmejeriet, Hultsfred

     The biomass gasification plant at the dairy Emåmejeriet is the only example in Sweden of something that has become more and more common in central and southern Europe, small scale gasification CHP plant.

     The dairy plant had been using a 500 kW light fuel oil boiler to provide its process heat, and where the temperature is required to be up to 105 °C. This has been replaced by the system depicted in Figure figure, i.e. an integrated fuel storage and dryer container feeding the gasifier, a modular biomass gasifier package unit from the Finish company Volter and two heat accumulators of a total volume of 10 m3 . The accumulators have the purpose of balancing the heat demand variations in the dairy operation and as a short-term back-up while the oil boiler is maintained for redundancy. The nominal output of the gasification plant is 40 kWe and 100 kWth.

Possible Future Development


Phoenix BTC concept

The BTC is a high-pressure, integrated process that converts biomass to electrical power. Gasification of biomass at high pressure, in combination with a high-pressure gas turbine process and massive steam injection in combination with extensive heat integration, achieves these unprecedented conversion efficiencies at low CAPEX and OPEX. At present the concept is studied while the technology elements are being developed at laboratory scale.
