Distillation Energy with distillation column connected load of 95 kW: a worked example

Push distillation column connected load up to 95 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when comparing distillation settings, batch sizes, utility assumptions, or quote cost for a concentrated aroma material.

The inputs for this scenario

  • Distillation column connected load: 95 kW (raised for this scenario; the documented default is 38)
  • Distillation cycle runtime: 6.5 hr (unchanged)
  • Blended electricity rate: 0.14 $ / kWh (unchanged)
  • Distilled product output weight: 320 kg (unchanged)

Working through the calculation

  • Applying the documented formula (Total distillation energy cost = distillation connected load × distillation runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 618 kWh for distillation energy energy used, the number this scenario is built around.
  • At this operating point the engine returns 86.45 $ for total distillation energy cost.
  • At this operating point the engine returns 0.27 $ / piece for energy cost per kg distilled.
  • At this operating point the engine returns 13.3 $ / hr for hourly distillation energy cost.

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 150% above the baseline at 618 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. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
