Reducing compliance costs of coal plants

Eco Power Solutions’ COMPLY 2000 multi-pollutant removal system has been named by the United States Environmental Protection Agency (EPA) to a short-list of technologies that “offer(s) the potential of reduced compliance costs and improved overall environmental performance”, according to the reference stated on pages 517-18 of the March 16, 2011, EPA proposed new source performance standards and MACT (Maximum Achievable Control Technologies) standards for fossil fuel-fired Electric Generating Units (EGUs).

As part of this proposed rule, one that would tighten performance standards for SO2, NOx and particulate matter for EGUs nationwide, the EPA is also proposing to provide incentives, including exemption from the new restricted standards, to a limited number of early adopters of newer and more promising multipollutant removal technology, such as the COMPLY2000.

Eco Power Solutions’ COMPLY 2000 claims to achieve emission reduction levels of:

• 99 per cent removal levels for sulfur oxides including sulfur dioxide (SO2) and sulfur trioxide

(SO3)

• 95 per cent removal of nitric oxide (NO) and nitrogen dioxide (NO2)

• 99 per cent removal of mercury (Hg)

• 99 per cent removal of 2.5 and 10-micron particulate matter

• 99 per cent removal of halogens including fluoride, chlorine and bromide and others

• 99 per cent removal of heavy metals including arsenic, cadmium, chromium and

others

• And an average of 20 per cent removal of carbon dioxide (CO2)

The scalable COMPLY 2000 is designed to remove multi-products of combustion typically classified as NOx, SO2, CO2, unburned hydrocarbons (UHC), particulate matter and heavy metals. The COMPLY 2000 eliminates all of these emissions from flue gases concurrently, therefore, controlling costs.

The COMPLY 2000 generates supplemental energy by recovering waste

heat that normally escapes into the atmosphere to help reduce a plant’s operating costs significantly.

COMPLY 2000 uses an ozone injection process for NOx conversion. A fogging spray is mixed with a hydrogen peroxide solution for SO2 conversion that is condensed concurrently with other pollutants over coils to remove all combustion emissions from the exhaust gas stream. This process converts NOx and SO2 to nitric and sulfuric acid in the wastewater stream collected at the bottom of the COMPLY 2000 unit.

Simultaneously, unburned hydrocarbons and particulate matter is removed during the condensation phase along with carbonic acid resulting from dissolved CO2. This wastewater can then be treated and
