Estimating particulate emissions from modern rock-crushing facilities involves assessing emissions from various processes such as crushing, screening, conveying, stockpiling, and operating haul roads. These facilities generate both fugitive dust (e.g., particles released during material handling) and exhaust emissions from equipment. Here’s a general process for estimating particulate emissions:
Identify all emission sources at the facility, which typically include:
Refer to established emission factors provided in:
Example emission factors for non-metallic mineral processing (AP-42):
These factors may vary based on particle size distribution, moisture level, and control equipment.
Determine the throughput or production rate in tons per hour (tph) for each emission source. Use process flow diagrams or equipment specifications.
If emission control systems (e.g., water spray systems, dry fog systems, or baghouse filters) are installed:
For uncontrolled fugitive dust emissions, estimate emissions using models or empirical relationships. Emission factors for haul road dust (for trucks or vehicles) are provided in AP-42 Chapter 13.2.2, considering variables such as:
Example formula from AP-42 for unpaved roads:\[ E = k \cdot \frac{{s}}{12} \cdot \frac{{W}}{3}^{a} \cdot \frac{{365 – P}}{365} \]
कुठे:
If empirical methods are insufficient, conduct direct air monitoring or testing to refine estimates. In many jurisdictions, rock crushers must comply with local air quality permits requiring regular emissions monitoring.
Consult any site-specific permits or regulatory requirements for additional methodologies or limits. Often facilities must demonstrate compliance via stack testing or visible emission limits (Opacity standards).
Develop a spreadsheet to aggregate all sources of emissions. Multiply production rate by emission factors and adjust for control efficiencies:
Several environmental agencies and consultants also offer software tools or calculators designed to help estimate emissions for quarrying and crushing facilities.
Integrating control measures and accurate production data will ensure realistic estimates of particulate emissions.
