Cryogenic Storage & LNG Equipment worked example

Cryogenic Pump Energy Load with cryogenic pump connected motor load of 30 kW: a worked example

This scenario runs the cryogenic pump energy load calculation on the strong side: cryogenic pump connected motor load of 30 kW, with every other input held at its documented default. Use it when cryogenic pump energy load in cryogenic storage and lng equipment is up for an upgrade and you want a defensible savings story.

The inputs for this scenario

  • Cryogenic pump connected motor load: 30 kW (raised for this scenario; the documented default is 12)
  • Pump runtime for transfer period: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Cryogenic liquid moved: 1,000 gal or kg (unchanged)

Working through the calculation

  • Applying the documented formula (Pump energy used = cryogenic pump connected motor load × pump runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for pump energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for cryogenic pump energy cost.
  • At this operating point the engine returns 0.03 $ / piece for pump energy cost per liquid unit.
  • At this operating point the engine returns 3.6 $ / hr for hourly pump energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where cryogenic pump connected motor load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • Use it to cost individual transfer operations, benchmark pump efficiency, or allocate pumping energy into per-unit product cost. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
