3h. CO2 Controls

What is Carbon Dioxide?

Carbon dioxide is a gas consisting of one atom of carbon and two atoms of oxygen. During combustion, the carbon (C) from the coal combines with oxygen (O2) from the air to produce carbon dioxide (CO2). Exposure to CO2 can produce a variety of health effects including headaches, dizziness, restlessness, tingling, a pins and needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions. 

CO2 is a significant contributor to air pollution, playing a substantial role in the greenhouse effect. This occurs as carbon dioxide traps radiation at the ground level, resulting in ground-level ozone. This prevents the earth from cooling during the night and warms ocean waters.

Controlling Carbon Dioxide Emissions

Capturing and storing carbon dioxide emissions is a critical area of research and development in the coal industry. Lesson 4 of this course will cover current technologies and issues in detail.
