The SilvaGas process is a gasifier that converts forest, agricultural and urban biomass residues (RDF), and municipal solid waste (MSW), and energy crops - collectively called biomass - into a medium-heating value gas that is directly substitutable for natural gas.
The SilvaGas process can be scaled into single unit plants ranging in capacity from 100 tons per day to more than 1,000 tons per day. In a gas turbine combined cycle, a 300 ton per day plant would produce enough product gas to generate more than 23 MW of electricity. Overall plant footprint for SilvaGas plant is about 1/3rd that of a conventional biomass boiler. The compact design has a high throughput 3,000 lb/hr-ft2 vs. competing technologies limitations of about 100 lb/hr-ft2
The strength of the SilvaGas process resides in its simplicity—the biomass is rapidly heated with hot sand. The SilvaGas process produces a medium-heating value gas (450-500 Btu/scf) at atmospheric pressure without the use of pure oxygen. Competing gasification technologies produce a low-heating value gas (50-200 Btu/scf) or require the added expense of pure oxygen to increase the heating value.
The SilvaGas process features a compact plant footprint. It is not an incineration or combustion based process, but a true advanced biomass gasification process. The process operates at near atmospheric pressure without the need for pure oxygen. Including the elimination of net CO2 additions to the environment, the SilvaGas process reduces environmental impact by 90% compared to typical fossil fuel based power plants. It consumes abundant, unused resources that would otherwise be disposed of in landfills or consumed in less efficient ways.
