Gas Blending Cost at 110% charged blend scope: a worked example

This scenario runs the gas blending cost calculation on the strong side: 110% charged blend scope, with every other input held at its documented default. Use it when quoting specialty gas mixtures, calibration gases, shielding gas blends, laser gases, lab gases, or process gas blends.

The inputs for this scenario

  • Blend gas volume: 2,400 SCF (unchanged)
  • Blended gas cost per volume: 0.18 $ / SCF (unchanged)
  • Charged blend scope: 110 % (raised for this scenario; the documented default is 100)
  • Fixed setup and analysis charge: 175 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable gas blending cost = blend gas volume × blended gas cost per volume × charged blend scope) to the inputs above produces each figure below.
  • At this operating point the engine returns 650 $ for total gas blending cost, the number this scenario is built around.
  • At this operating point the engine returns 0.27 $ / SCF for blended gas cost per volume.
  • At this operating point the engine returns 475 $ for variable gas blending cost.
  • At this operating point the engine returns 175 $ for fixed setup and analysis charge.

How this compares with the baseline

  • Against the tool's baseline example, where charged blend scope sits at 100% and the headline result is 607 $, this scenario comes in 7.12% above the baseline at 650 $.
  • Use it when quoting or costing a custom specialty blend, calibration standard or shielding mixture where mixing labor and certification add a fixed charge on top of metered gas. 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

  • Total gas blending cost: 650 $ (headline result)
  • Blended gas cost per volume: 0.27 $ / SCF
  • Variable gas blending cost: 475 $
  • Fixed setup and analysis charge: 175 $
