For decades, plant operators and manufacturers have focused on increasing their production rates while simultaneously reducing energy consumption. This process of increasing efficiency and saving costs will continue in the future. In addition, however, the requirements of increasingly stringent government regulations on environmental protection must also be met. The stricter emission requirements thus create a constant pressure to invest and innovate. This is why technologies for air pollution control play an important role in the cement, waste incineration and power plant industries – as they do in many other industries.
Production and combustion processes in various industries are major sources of emissions of air pollutants. The four most important pollutant categories are
- Mercury (Hg),
- Sulphur dioxide (SOx) and
- Nitrogen oxides (NOx).
The various applications of gas cooling and gas conditioning support the reduction of these pollutants.
