THE SKYMINE PROCESS:

Skyonic’s SkyMine® technology removes CO2 from industrial waste streams through co-generation of saleable carbonate and/or bicarbonate materials. In addition to capturing and mineralizing CO2, the SkyMine® process cleans SOx and NO2 from the flue gas, and removes heavy metals such as mercury. Existing power plants and industrial plants can be retrofitted with SkyMine®. Successful implementation of the SkyMine® technology establishes pathways for mitigating CO2 in areas where geologic storage, the predominant competing CO2 sequestration technology, is not an optimal solution.

A SkyMine® plant can be retrofitted to stationary emitters to economically remove CO2 from the exhaust stream and transform it into solids instead of a gas. Solid carbonates and bicarbonates can be profitably sold to market and are ideal for long-term, safe storage such as minefill or landfill. Solid storage of CO2 means that there is no need for pipeline transport, injection, or concern about CO2 re-release, as with other CO2 capture and sequestration technologies.

Another key advantage of the SkyMine® process is its scalability, as it allows an industrial or power plant owner to configure the degree of CO2 removal anywhere from 10% to 99%. This is important because industrial plants and power plants around the world have unique designs requiring different CO2 removal configurations.

The SkyMine® technology can be operated at a profit, due to the sale of byproducts. The solid carbonates and bicarbonates are saleable for use in bio-algae applications. SkyMine® also produces green chemicals, such as hydrochloric acid, bleach, chlorine, and hydrogen, which are also profitable and can replace less environmentally-friendly products in market.

The fact that the SkyMine® process removes virtually all SOX, NO2, and mercury and other heavy metals that would otherwise be emitted by the plant means it can replace existing scrubber technologies and eliminate hundreds of millions of dollars in capital expense and tens of millions of dollars in ongoing expenses.
