Industrial Process Emissions Reduction

Technical details

The United States is the largest consumer of energy in the world and consequently millions of gallons of transformer oil reach the end of its service each year. Transformer oil or insulating oil is a highly-refined oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, as well as some types of high-voltage capacitors, switches and circuit breakers. Its functions are to insulate, suppress corona and arcing and to serve as a coolant.

When transformer oil reaches the end of its life, it is usually unfit for further use because of its accumulated contaminants and the loss of electrical, chemical and physical performance. However, using advanced technology, it is possible to treat this oil and recycle it. Reclamation of this kind of oil avoids emissions because the waste oil is most typically incinerated, destroying its toxic contaminants. This incineration causes CO2 emissions, which can be avoided through re-refining and re-use. Oil used in the electricity distribution sector also contains Polychlorinated Biphenyls (PCBs), and this project requires the proper treating and disposal of PCBs which are a known carcinogen. One main environmental benefit of the project is therefore the elimination of health and safety risks associated with the destruction of PCBs. This project will involve a re-refining facility that is putting used oil back into service, thus avoiding emissions from the combustion of that oil.

Environmental Management of KC, LLC (EMI) was founded in 1997 in Kansas City, Kansas. The purpose of EMI is to meet the needs of the utility industry and associated industries in handling their used, non- hazardous transformer oil. At the same time, EMI has allowed the generator to reduce their carbon footprint by recycling the used oil for future reuse.

Since inception, EMI has utilized a process of chemical dechlorination to effectively remove the polychlorinated biphenyl (PCB) content of transformer oil to <2 ppm thereby ending the liability chain for clients. This process is still in operation today, and will continue to be utilized for hard to handle PCB oil. In 2013, EMI added a second treatment process with which to handle and re-refine transformer oil.

With this proprietary hydro-treating process, EMI is not only recycling the waste for clients, but re- refining the oil back to virgin standards. It is this second treatment is where the net GHG reductions are taking place.

Cloverly buys offsets that meet accepted standards for being real, measurable, verifiable, permanent, and additional. "Additional" means that the carbon savings would not have happened without the offset project and that the project would not have happened unless it got certified to sell carbon offsets.
