Mixing, Blending & Industrial Batch Processing worked example

Viscosity Adjustment at 99% process correction factor: a worked example in mixing, blending & industrial batch processing

This scenario runs the viscosity adjustment calculation on the strong side: 99% process correction factor, with every other input held at its documented default. Use it when an in-process viscosity check is off-spec and the operator needs a quick adjustment ratio before adding solvent, thickener, or a let-down resin.

The inputs for this scenario

  • Current batch viscosity: 1,450 cP (unchanged)
  • Target viscosity: 1,200 cP (unchanged)
  • Process correction factor: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Viscosity ratio = current batch viscosity รท target viscosity) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.2 ratio for effective throughput, the number this scenario is built around.
  • At this operating point the engine returns 1.21 ratio for raw throughput.
  • At this operating point the engine returns 99 % for efficiency.
  • At this operating point the engine returns 1,200 hr for runtime.

How this compares with the baseline

  • Against the tool's baseline example, where process correction factor sits at 90% and the headline result is 1.09 ratio, this scenario comes in 10% above the baseline at 1.2 ratio.
  • Use it at in-process QC checks to judge whether a batch is on, above, or below target viscosity before deciding to adjust or release. 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

  • Effective throughput: 1.2 ratio (headline result)
