Air Pollution Control for a Hot Mix Asphalt Plant

Abstract

The report explores how to reduce pollution by improving the emission control system in Hot Mix Asphalt (HMA) plants. The majority of emissions come from the combustion of fuel and particulate matter (PM) diffusion. The key finding is that combining a wet scrubber system and baghouse system will reduce the major pollutants significantly. Thousands of HMA plants across the country are in operation every day in rural, suburban, and urban areas, affecting all neighbors in their local communities. How an asphalt plant impacts the neighborhood and the environment mainly depends on their sustainable operation. Asphalt plant emissions are very low and getting lower due to innovative control systems and manufacturing technology. The objective of this report is to exppore the emission control system of a Hot Mix Asphalt plant. The main point is how to improve the scrubber system and baghouse filter for controlling criteria pollutants in the Hot Mix Asphalt plant during production to reduce the emissions.
