Why is it important to consider the entire size range of particulate matter emissions when designing control strategies?

Expert Solution

While designing control emissions, the main focus is to reduce the particulate emmision by reducing the amount of Total Suspended Particles (TSP). These suspended particles could be of two types:
Primary particulate matter and Secondary particulate matter.
While the primary particulate matter is relatively larger in size (could vary from 0.1 micrometer to more than 100 micrometres), on the other hand the secondary particulate matter is fine to ultra fine in size distribution.
The secondary particulate matter is formed by the reaction between the gaseous emissions from anthropogenic sources and their accumulation leads to the formation of a variety of sizes of particulate matter.
Hence, even if the emissions form sources are of a particular size range, it could still act as a precursor for the formation of suspended partices of different size range.
Therefore, it is always important to consider the entire size range of particulate matter emissions while designing control strategies.

Electrostatic precipitator question, I'm designing an electrostatic precipitator (ESP) to capture the particulate matter(fly ash) from flue gas at 130C that exits from a coal-fired power plant. My question is: how can i increase the efficiency of the electrostatic precepitator without conditioning the flue gas (ie. injecting so3 or ammonia or water)? what are the alternative ways to increase the efficiency of the ESP? please show references with solution. Thanks

When designing a compensation system for an organization, it is important to have a compensation philosophy which serves as a framework for making decisions about various components of the system. Tasks: One question to be addressed is how can your compensation program help the organization be successful (e.g., be able to attract and retain talented workers needed to be competitive in the marketplace)? Some options for consideration include: Being an “employer of choice” in the industry Offering top salaries Putting...
