Comparing stream concentrations cannot establish the mass of a compound removed unless stream quantities and reporting bases are also known.
Concentration may still be the appropriate specification when exposure or product identity is the question. The required metric follows the decision.
The Alcarde tables reproduced in Batch Distillation use concentrations normalized to anhydrous alcohol. A lower value describes that basis; total transfer additionally requires the amount of alcohol or liquid represented. This distinction prevents a percentage reduction table from being mistaken for a complete material balance.
Original synthesis from full-source Batch Distillation review; concept-level duplicate searches performed. Developing, not an independently validated operating procedure.
Atomic Idea
Comparing stream concentrations cannot establish the mass of a compound removed unless stream quantities and reporting bases are also known.
Reasoning
The Alcarde tables reproduced in Batch Distillation use concentrations normalized to anhydrous alcohol. A lower value describes that basis; total transfer additionally requires the amount of alcohol or liquid represented. This distinction prevents a percentage reduction table from being mistaken for a complete material balance.
Boundary
Concentration may still be the appropriate specification when exposure or product identity is the question. The required metric follows the decision.
