Fluidized Bed Combustion

A method that burns granulated coal in close proximity to calcium carbonate (limestone) to absorb SO2.

Calcium Carbonate (CaCO3)

A substance that absorbs sulfur dioxide (SO2) during Fluidized Bed Combustion.

Gypsum Wallboard

A product made from the byproduct of calcium sulfate (Ca3(SO4)2) after absorbing SO2 in Fluidized Bed Combustion.

Catalytic Converter

A device in cars that decreases NOx and CO emissions using a redox reaction.

Controlling NOx Emissions

In industries, it can be achieved by burning coal and oil at lower temperatures and controlling oxygen.

Gravitational Settling

The simplest means of pollution control where particles settle to the bottom due to gravity.

Baghouse Filters

Fabric filters that allow gases to pass but not particulate matter (PM), some can remove 100% of PM.

Electrostatic Precipitators

Devices that use an electrical charge to make PM clump together for removal.

Wet Scrubbers

Devices that use water and air to separate and remove PM, also effective in removing SO2.

Regulatory Practices

Approaches taken, such as restricting VOCs and implementing conservation measures, to reduce emissions.

Alternative Fuels

Fuels that can be used to reduce emissions, promoted through innovative pollution control measures.

VOCs

Volatile Organic Compounds that contribute to air pollution and can be managed through regulatory practices.

Mexico City's Driving Schedule

An initiative aiming to reduce VOCs and NOx by instituting an every other day driving regulation.

China's Driving Restrictions (2008 Olympics)

Strict driving limitations imposed during the Olympics to improve air quality.
