Distillation Energy with distillation column connected load of 19 kW: a worked example

Suppose distillation column connected load falls to 19 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate energy cost for distilling, concentrating, stripping, or recovering aroma chemicals, extracts, essential oils, or solvents.

The inputs for this scenario

  • Distillation column connected load: 19 kW (the input this scenario stresses; the baseline uses 38)
  • Distillation cycle runtime: 6.5 hr (held at the documented default)
  • Blended electricity rate: 0.14 $ / kWh (held at the documented default)
  • Distilled product output weight: 320 kg (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total distillation energy cost = distillation connected load × distillation runtime × blended electricity rate.
  • Distillation Energy energy used works out to 124 kWh at these inputs, and this is the headline figure for the scenario.
  • Total distillation energy cost works out to 17.29 $ at these inputs.
  • Energy cost per kg distilled works out to 0.05 $ / piece at these inputs.
  • Hourly distillation energy cost works out to 2.66 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where distillation column connected load sits at 38 kW and the headline result is 247 kWh, this scenario comes in 50% below the baseline at 124 kWh.
  • It computes total kWh from connected load and runtime, multiplies by the electricity rate for total cost, and divides by distilled output to give energy cost per kilogram. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
