Emissions Capture Rate at 99% target emissions capture rate: a worked example

This scenario runs the emissions capture rate calculation on the strong side: 99% target emissions capture rate, with every other input held at its documented default. Use it when reviewing dust, fume, mist, or particulate capture for EHS compliance and source control performance.

The inputs for this scenario

  • Captured contaminant mass: 970 lb (unchanged)
  • Generated contaminant mass: 1,000 lb (unchanged)
  • Target emissions capture rate: 99 % (raised for this scenario; the documented default is 98)

Working through the calculation

  • Applying the documented formula (Emissions capture rate = captured contaminant mass ÷ generated contaminant mass × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 97 % for emissions capture rate, the number this scenario is built around.
  • At this operating point the engine returns 2 points for emissions capture gap to target.
  • At this operating point the engine returns 970 count for captured contaminant mass.
  • At this operating point the engine returns 1,000 count for generated contaminant mass.

How this compares with the baseline

  • Against the tool's baseline example, where target emissions capture rate sits at 98% and the headline result is 97 %, this scenario lands almost exactly on the baseline at 97 %.
  • Use it when validating hood capture efficiency, reporting on air-permit performance, or troubleshooting a source that fails an exposure or opacity check. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Emissions capture rate: 97 % (headline result)
  • Emissions capture gap to target: 2 points
  • Captured contaminant mass: 970 count
  • Generated contaminant mass: 1,000 count
