Removing Sulphur for Recovering and Converting Farm Methane Emissions into Clean Energy

Renewable Natural Gas Transforms Agriculture and the Environment and promotes renewable energy. Waste from large-animal farms is both a potent source of greenhouse gases and a source of pipeline-quality renewable natural gas.
By capturing bio-methane from this agricultural waste, we can reduce methane emissions, decrease production of fossil fuels, diversify income for farmers, and reduce air pollution.
Methane capture from farm waste is essential to our clean energy future. Utilizing renewable natural gas brings us closer to carbon neutrality with technology that is available today.

Methane capture benefits farmers and farming communities in many different ways. The bio-methane produced from on-site anaerobic digestion can be either a source of fuel for the farmer or an independent revenue stream if the bio-methane is sold to a third party. Also, a “fringe benefit” of manure digestion is that the digestion process that captures the waste methane also converts the nutrients in the waste to a more accessible form, creating a higher-quality fertilizer than unprocessed manure. In addition, other by-products of digested waste can be used on-site or sold as animal bedding and other products (see image below). And as a combo perk (environmental + farming), manure digesters also lower the pathogen risks to crops and animals and decrease run-off pollution to nearby waterways, which is good for everyone. Last but definitely not least, digested manure is largely odorless, which is a significant health and quality-of-life benefit for both large-scale animal farmers and their communities.

Non-regenerative Sulphur Adsorbents

The following table represents non-regenerative adsorbents.

Adsorbent Type Applications Shape Benefits

ADS NS-75 Nickle H2S/COS/Mercaptans C0 and heavy sulfides Extrudate Mild Sulfur capacity Broad sulfur species
ADS LAS-20 PbO COS/Arsine/Sulfur/PH3 Sphere Mild Sulfur capacity Broad sulfur species
ADS ASR CuO/AI203 H2S/COS/Mercaptans/Arsine/PH3 from both liquid and gas Sphere Mild Sulfur capacity Low Density

Sulphur is an organic element exists in the waste and gets released in form of H2S that needs to be captured. Since the amount of H2S is not significant therefore, H2S scavenger with Iron Oxide based adsorbent are the perfect solution to remove the H2S followed by dryer. RATE has OEM Manufacturing that produces different type of adsorbents for these application for renewable energy. Please refer to Product section for more details.
