Vacuum feedback control / PID [Text] - PLCS.net .

Pressure control is a common application for a VFD, so there is already a start-up configuration built in to most VFDs. Pressure control is close enough to the same as vacuum control (vacuum is still a "type" of pressure) however the PID control direction may be direct and not reverse.

Chemical Industrial Reactor Vacuum | Nash

Vacuum is used mainly to lower the reaction temperature and to conserve energy. Process control, solvent/vapor recovery, and evaporation recovery are also valuable. Reactor vacuums are used in manufacturing bulk pharmaceuticals, removing glycol from polyester, producing ammonia, and forming both organic and inorganic compounds.

Controlling Vacuum Distillation - Equilibar

Controlling Vacuum Distillation - Equilibar

Some vacuum applications require precise control at very high vacuum in the range of 100 microns Hg (abs) or 0.1 mbar (abs). These conditions can be hard to control, but in a closed-loop automated setup, Equilibar EVR vacuum regulators can control high vacuum. This may be of particular use in vacuum distillation or other analytical vacuum .
