Solid-Liquid Separation: Classification, Design and Testing

Whether to remove solid contaminants from a liquid or separate a solid product from a solvent, solid-liquid (S-L) separation is a common unit operation across the chemical process industries (CPI). This one-page reference provides an overview of S-L separation methods,…

Fine Vacuum Control

Many important research and industrial processes require vacuum in what is referred to as the "fine vacuum" range, which is between 0.1 and 0.001 Torr. In a prior post, we talked about the fact that the Pirani style gauge is…

Vacuum Pump Sizing – Evacuating a Chamber

We've previously talked about some of the tools we've made available to help select the right vacuum pump for your work.  Our pump selection guide is a great choice if you have a strong sense of your operating parameters.  And for drying…

Advanced Vacuum Control

Our most recent post addressed the benefits of proportional-only vacuum process control. Though this approach is well suited to many processes, in some cases more accurate (or precise) control of the pressure level is necessary.  Under such circumstances, employing PI…

Proportional (2 Point) Vacuum Control

In our prior post, we talked about using variants of the classic PID algorithm in order to control vacuum processes.  In the simplest form, the PID control loop can be reduced to a P-only, or 2-point, algorithm.  For example, by…
