Siloxane Destruction

Siloxane Corrosion
Siloxane Corrosion 2

As contents of landfills decompose, they release siloxanes, non-toxic compounds that are frequently added to consumer products, such as detergents, shampoos, deodorants (to improve texture and feel), cosmetics, paper coatings and many textiles. While some siloxanes quickly volatilize into the atmosphere, others remain present and can be found in the biogas.

Siloxanes have damaging effects on landfill equipment, potentially causing costly corrosion. With some researchers estimating that siloxanes are at every landfill site in North America and Europe, landfill operators and gas-to-energy project managers are spending more time investigating siloxane levels. Newer landfills are more likely to result in higher concentrations of siloxanes, due to consumer consumption and the increase of siloxane use in consumer goods.

Use of an ABUTEC Siloxane Flare, or “off-gas flare,” can turn a potentially corrosive situation into a positive gas-to-energy project. These flares can burn siloxanes and, in combination with a siloxane removal system, can feed the byproducts back into the power grid, creating less harmful waste and a green solution to wasted energy.



Because siloxanes can damage expensive equipment, including combustion engines and turbines, use of an ABUTEC siloxane flare can burn off these compounds, saving your infrastructure and avoiding costly repairs and replacements.



Siloxanes form silica and silicate deposits, which are difficult to remove from equipment. This can lead to the abrasion of engine parts and often result in changes to the combustion chamber. In some cases, this induces higher emissions of carbon monoxide and formaldehyde, possibly violating air emissions regulations.



Addition of siloxanes to consumer products (such as detergents, shampoos, deodorants, cosmetics and paper coatings) is expected to increase as consumption and demand increases. Stay on top of managing your infrastructure by proactively installing an ABUTEC Siloxane Flare.

Flaring Features

The Coca-Cola/Mas Energy Trigeneration Facility near Atlanta utilizes siloxane regeneration technology from a nearby landfill to provide the energy needed to source its operations. It is estimated that through use of this regeneration technology, the facility will generate at least 48 million kWh of on-site renewable energy annually. Download case study.

The ABUTEC siloxane regeneration flare was also used in the Taylor County Landfill, the largest landfill gas-to-electricity project in the state of Georgia.
