Dry Ice Usage with dry ice sublimation use rate of 11 lb / hr: a worked example

This scenario runs the dry ice usage calculation on the strong side: dry ice sublimation use rate of 11 lb / hr, with every other input held at its documented default. planning dry ice pull quantities and cost for frozen shipments or emergency cooling

The inputs for this scenario

  • Dry ice sublimation use rate: 11 lb / hr (raised for this scenario; the documented default is 4.5)
  • Lane, hold, or packout duration: 36 hr (unchanged)
  • Dry ice cost per pound: 1.35 $ / lb (unchanged)

Working through the calculation

  • Applying the documented formula (Dry Ice Usage required = dry ice use rate × lane, hold, or packout duration) to the inputs above produces each figure below.
  • At this operating point the engine returns 396 lb for dry ice usage required, the number this scenario is built around.
  • At this operating point the engine returns 535 $ for total dry ice usage cost.
  • At this operating point the engine returns 36 hr for lane, hold, or packout duration.
  • At this operating point the engine returns 1.35 $ / unit for dry ice cost per pound.

How this compares with the baseline

  • Against the tool's baseline example, where dry ice sublimation use rate sits at 4.5 lb / hr and the headline result is 162 lb, this scenario comes in 144% above the baseline at 396 lb.
  • Use it when planning a frozen packout, qualifying a lane's coolant load, or estimating consumable spend for a temperature-controlled route. 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

  • dry ice usage required: 396 lb (headline result)
  • total dry ice usage cost: 535 $
  • lane, hold, or packout duration: 36 hr
  • dry ice cost per pound: 1.35 $ / unit
