Question

Quizplus · Accepted Answer

Scrubbers are the devices used to remove sulfur oxides (SOx) from the emissions of coal-fired power plants. They work by using a liquid, usually a mixture of water and limestone, to absorb the SOx before they are released into the atmosphere. This process is also known as flue gas desulfurization. Catalytic converters are devices used in automobiles to reduce emissions of harmful gases such as carbon monoxide, nitrogen oxides, and hydrocarbons. Desulfinators are not a commonly known technology for air pollution control, and CFCs (chlorofluorocarbons) are chemicals that were used in refrigeration and air conditioning systems but have been banned because they damage the Earth's ozone layer.
