VOC Emissions Estimate with voc emission rate of 1.9 kg / hr: a worked example

This worked example runs the voc emissions estimate numbers for a tougher week than the baseline: voc emission rate of 1.9 kg / hr instead of the typical 3.8 kg / hr. Estimate voc emissions estimate from voc emission rate, process operating time, and voc control or retention multiplier.

The inputs for this scenario

  • VOC emission rate: 1.9 kg / hr (the input this scenario stresses; the baseline uses 3.8)
  • Process operating time: 160 hr (held at the documented default)
  • VOC capture and control efficiency multiplier: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base amount = voc emission rate × process operating time.
  • Base VOC emissions before multiplier works out to 304 kg at these inputs, and this is the headline figure for the scenario.
  • VOC Emissions Estimate works out to 304 kg at these inputs.
  • Process operating time works out to 160 hr at these inputs.
  • VOC control or retention multiplier works out to 1 x at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where voc emission rate sits at 3.8 kg / hr and the headline result is 608 kg, this scenario comes in 50% below the baseline at 304 kg.
  • Use it to project permit-period emissions, screen against reporting thresholds, or model the emission reduction from adding a control device. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Base VOC emissions before multiplier: 304 kg (headline result)
  • VOC Emissions Estimate: 304 kg
  • Process operating time: 160 hr
  • VOC control or retention multiplier: 1 x
