Separator Capacity at 65% separator uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop separator uptime to 65%, then walk the calculation through step by step. Estimate accepted separator output from volume per cycle, available cycles, uptime, and first-pass separation yield.

The inputs for this scenario

  • Separated fluid volume per cycle: 500 gal / cycle (held at the documented default)
  • Scheduled separator cycles: 18 cycles (held at the documented default)
  • Separator uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass separation yield: 94 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross separator capacity = separated volume per cycle × available separator cycles.
  • Accepted separator capacity works out to 5,499 gal at these inputs, and this is the headline figure for the scenario.
  • Gross separator capacity works out to 9,000 gal at these inputs.
  • Separator downtime loss works out to 3,150 gal at these inputs.
  • First-pass separation yield loss works out to 351 gal at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where separator uptime sits at 90% and the headline result is 7,614 gal, this scenario comes in 27.78% below the baseline at 5,499 gal.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to separator uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes consistent influent; a slug of emulsified oil or fine swarf can crash first-pass yield well below the modeled value, so confirm yield under worst-case loading.

Results at a glance

  • Accepted separator capacity: 5,499 gal (headline result)
  • Gross separator capacity: 9,000 gal
  • Separator downtime loss: 3,150 gal
  • First-pass separation yield loss: 351 gal
