Oregon based renewable energy engineering and construction specialist, ENERGYneering Solutions Inc. (ESI) has signed a supply and service contract for Danish firm, Topsoe’s, proprietary HiPerFuel™ landfill gas conditioning solution for its landfill gas power plant in Washington State.
The solution removes siloxanes and sulfur from landfill gas to provide high-purity fuel gas.
“The solution Topsoe is offering is unique to the industry in that it offers high siloxane removal efficiency and long media life comparable with many of the regenerative systems on the market while avoiding the typically high capital and operating costs associated with dehydration of the gas and thermal oxidation of waste gases,” explained William Song, director of engineering, ESI.
The company added that Siloxanes are an inherent problem for the more than 500 landfill gas power plants in the U.S. During combustion they convert into sand-like particles that cause deposits and erosion inside power generating equipment that leads to excessive maintenance costs and down-time.
For those plants that utilise backend treatment to improve engine exhaust emissions, siloxanes can also cause significant damage to emissions control catalysts.
“We are offering proprietary solutions that have been tried and tested in other industries and they will enable the industry to take an important step forward,” commented Kresten Egeblad, business development manager, Topsoe Sustainables.
