FOS/TAC Titration

The FOS/TAC ratio is a commonly used indicator for assessing the fermentation process within biogas reactors, where FOS is a measure of the volatile organic acids (measured in mg CH3COOH/l) and is TAC is a measure of the total inorganic carbon i.e. the alkaline buffer capacity of the system (measured in mg CaCO3/l). In simple terms, this ratio looks at acid vs alkaline in the system which helps...

What is TAN - Total Acid Number

Total Acid Number (TAN): [caption id="attachment_5085" align="aligncenter" width="300"] Oil testing[/caption] Total Acid Number (TAN) is a measure of the quantity of acidic compounds present in a petrochemical sample. The TAN value is determined for both new and used oil samples. New oils are monitored to ensure the initial quality of the oil meets the specific TAN range for the sample type. U...
