This paper is about using a non-thermal plasma process to remove pollutants from emissions.
It is probably a good idea to begin with the definition of non-thermal plasma. As we learned in
grade school, matter exists in three phases: solid, liquid, and gas (for example; ice, liquid, and
vapor are the three phases of water). What Miss Bromley didn’t tell you is that there is a fourth
phase in which matter can exist. This phase is called plasma, and it exists when molecules are
heated to extremely high temperatures. At high temperature, electrons in molecules become
excited and increase velocity to a point they leave their orbits and fly out of the molecule’s
influence. As the non-thermal plasma name implies, plasma also can occur at room temperature
if the molecules are exposed to a strong electrical field. More on this later.
