Purge Component Retention Share Tool

Apply explicitly supplied component purge/retention shares without a chemical process model.

Description

Return purged and additionally retained recycle component.

Process balances distinguish fresh, recycled, purged and reacted quantities on a common time and material basis. Local residuals or geometric retention factors can diagnose supplied bookkeeping, while actual steady state, feasible composition and reaction performance require a complete physical model.

Return purged and additionally retained recycle component.

When to use this tool

Use Purge Component Retention Share when checking the stated recycle, purge, conversion or balance convention.

How to use the tool and how it works

  1. Enter componentInRecycle, purgeFraction, suppliedRetainedShare. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read purgedComponent, retainedComponent. Use the output convention below.

Return purged and additionally retained recycle component. Require componentInRecycle >= 0 and purge/retained fractions in [0,1]; purged = component*purge, retained = component*(1-purge)*suppliedRetainedShare.1

Limitations and assumptions

  • Unretained losses remain outside these two outputs; no actual component recovery or complete mass balance is verified.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Reconcile every relevant stream and component with compatible units; validate the complete steady-state or dynamic process model and actual material properties.
