Steam Cost with steam use rate of 11 klb / hr: a worked example

Push steam use rate up to 11 klb / hr and the picture changes. This example computes every intermediate figure at that operating point. assigning steam cost to a batch, heating step, or utility-intensive process run

The inputs for this scenario

  • Steam use rate (klb/hr): 11 klb / hr (raised for this scenario; the documented default is 4.5)
  • Process runtime at that rate: 3 hr (unchanged)
  • Loaded steam cost per 1,000 lb: 14 $ / klb (unchanged)

Working through the calculation

  • Applying the documented formula (Steam consumption = steam use rate × runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 462 $ for run cost, the number this scenario is built around.
  • At this operating point the engine returns 33 klb for steam consumed.
  • At this operating point the engine returns 3 hr for steam runtime.
  • At this operating point the engine returns 14 $ / klb for steam cost per thousand pounds.

How this compares with the baseline

  • Against the tool's baseline example, where steam use rate sits at 4.5 klb / hr and the headline result is 189 $, this scenario comes in 144% above the baseline at 462 $.
  • It computes the total dollar cost of steam consumed over a run from your use rate, runtime, and loaded cost per thousand pounds. 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.
