The volumetric productivity is an important concept of Chemical engineering. It characterizes the quantity of produced formed in a engine per unit of volume during a given time.

Its unit is s^-1 l^-1, or s^-1 l^-1.

The calculation of the volumetric productivity rests on the knowledge of the kinetic as well as Sélectivité of the reaction, it also requires a choice of the Convertion rate. This calculation makes it possible to predict if the performance (or Cible of production), can be reached.
