INTERCHANGEABLE WITH NATURAL GAS AND FUEL OIL

The SilvaGas process produces a medium-Btu gas (450-500 Btu/scf) at atmospheric pressure without the use of pure oxygen. Competing gasification technologies either produce low value gas (50-200 Btu/scf) or require the added expense of pure oxygen to increase the heating value.

Our product gas can be used in conventional equipment designed for natural gas or fuel oil without modifications. In Contrast, the low-Btu product gas from other gasifiers requires specially modified equipment to utilize the gas.

HIGH EFFICIENCY

Power generation efficiency of a plant in a combined cycle can be twice the efficiency of biomass combustion processes, due to efficiency of combined cycle versus steam cycle alone.

Advanced fuel cell applications using the SilvaGas process will result in power generation efficiencies more than three times those of biomass combustion processes.

HIGH-THROUGHPUT/COMPACT

High throughput 3,000 lb/hr-ft2 versus competing technologies limitations of about 100 lb/hr-ft2.

Compact system leads to lower capital costs.Overall plant footprint for SilvaGas plant is about 1/3rd that of a conventional biomass boiler.

FUEL FLEXIBILITY

The SilvaGas process accepts wood chips, sawdust, shredded bark and stumps, prepared municipal solid waste, agricultural waste, chicken litter and energy crops such as switchgrass and hybrid poplar.

The heating value of the product gas remains constant despite variations in feedstock moisture levels. Product gas from conventional gasification systems varies greatly with feedstock moisture content, requiring complex and expensive equipment to handle the fluctuations.

CLEAN & GREEN

Emissions are CO2 neutral because CO2 released is absorbed in the growth cycle of new biomass feedstocks.

High energy density simplifies product gas cleanup.

The SilvaGas indirect gasification process greatly reduces the production of combustion byproducts that plague conventional combustion and gasification systems.

Nitrogen in fuel is not converted to NOx. Minimized NOx emissions due to process conditions.

No SOx from biomass feedstocks.

Chlorine in fuels is converted to HCl, which is easily removed from product gas. Conventional biomass fired boilers create dioxin from chlorine combustion.
