Distillation

Distillation, sometimes referred to as fractionation or rectification, is a process for the separating of two or more liquids. The process utilizes the difference of the vapor pressures to produce the separation.

Distillation is one of the oldest unit operations. While the first technical publication was developed in 1597, distillation already had been practiced for many centuries — specifically, for the concentration of ethyl alcohol for beverages. Today, distillation is one of the most used unit operations and is the largest consumer of energy in the process industries.

APV has been conducting business in the field of distillation since 1929. A brief history of APV in distillation is shown in Figure 1.

Today, APV mainly concentrates its marketing efforts in the area of solvent recovery, waste water stripping, chemical production and specialized systems, such as high vacuum systems for oils.
