Description
Return recycle, recovered-recycle and unrecycled flows.
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 recycle, recovered-recycle and unrecycled flows.
When to use this tool
Use Recycle Split Flow Factor when checking the stated recycle, purge, conversion or balance convention.
How to use the tool and how it works
- Enter grossFlow, recycleFraction, suppliedRecoveryFraction. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read recycledFlow, recoveredRecycle, netUnrecycled. Use the output convention below.
Return recycle, recovered-recycle and unrecycled flows. Require grossFlow >= 0 and recycle/recovery fractions in [0,1]; recycled = gross*recycle, recovered = recycled*recovery, netUnrecycled = gross*(1-recycle).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| grossFlow | Gross Flow | Required. Finite number; minimum 0. |
| recycleFraction | Recycle Fraction | Required. Finite number; minimum 0; maximum 1. |
| suppliedRecoveryFraction | Supplied Recovery Fraction | Required. Finite number; minimum 0; maximum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| recycledFlow | Recycled Flow | Required. Finite number. |
| recoveredRecycle | Recovered Recycle | Required. Finite number. |
| netUnrecycled | grossFlow-recycledFlow; excludes additional unrecovered recycle loss. | Required. Finite number. |

}Limitations and assumptions
- Recovered-recycle loss is not included in netUnrecycled; no full process balance or recovery performance 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.
