Gas purifying solution will drive down operational costs at landfill gas power plants

US based landfill gas industry O & M contractor and engineering company ENERGYneering Solutions Inc. (ESI) have signed a supply and service contract for Topsoe’s proprietary HiPerFuel landfill gas conditioning solutions. The HiPerFuel unit will deliver high-purity fuel gas for an ESI landfill gas power plant in Washington State.

The contract is the first deal signed for Topsoe’s HiPerFuel landfill gas conditioning solution. The new solution is designed to demonstrate the effects of high-purity landfill gas for power plants by driving down operational costs and downtime for landfill gas power plant operators.

“We are excited about the possibilities with this new solution from Topsoe. 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. We are very much looking forward to seeing the effects of running our engines on a siloxane-free gas,” said William Song, Director of Engineering at ESI.

The solution removes siloxanes and sulphur from landfill gas to provide high-purity fuel gas. Siloxanes are a major problem for the 500 land-fill gas power plants in the US. During the combustion process they convert into sand-like particles which cause deposits and erosion in power generating equipment, leading to excessive maintenance costs and downtime. Siloxanes can also cause significant damage to emissions control catalysts.

“In Topsoe, we are thrilled to offer best-in-class solutions for fuel pre-treatment, renewable natural gas and advanced emissions control for the landfill gas industry. 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. ESI is an innovator within the industry, and we look forward to our collaboration”, said Kresten Egeblad, Business Development Manager at Topsoe Sustainables, in a press release.
