FAQ

What is the Feed Flowrate?

Feed Flowrate is defined as the molar flowrate of the feedstock that is sent into a distillation column. Feed Flowrate is usually measured using the Mole per Second for Molar Flow Rate. Note that the value of Feed Flowrate is always positive.

Can the Feed Flowrate be negative?

No, the Feed Flowrate, measured in Molar Flow Rate cannot be negative.

What unit is used to measure Feed Flowrate?

Feed Flowrate is usually measured using the Mole per Second[mol/s] for Molar Flow Rate. Kilomole per Second[mol/s], Dekamole per Second[mol/s], Mole per Minute[mol/s] are the few other units in which Feed Flowrate can be measured.
