Facts At Your Fingertips: Predictive Maintenance Methods

Predictive maintenance (PdM) programs can provide advanced warning of equipment problems and potential failures. This one-page reference provides brief descriptions of six common predictive maintenance methods. Infrared thermography Continuous monitoring of equipment temperature over time has the potential to identify…

High-shear mixers for fine dispersions and emulsions

Batch high-shear mixers equipped with the Solids/Liquid Injection Manifold (SLIM) Technology (photo) deliver powders in an efficient manner for quick wet-out and complete dispersion into low-viscosity liquids. In a conventional rotor/stator mixer, materials are continually drawn from below the mixing…

Gas Trapping Can Unsettle Distillation Columns

Operational troubleshooting guidance is provided for several scenarios involving trapped non-condensable gases in distillation towers Non-condensable gases are often present in distillation towers, either expectedly or unexpectedly. When they do appear, or when the quantity of non-condensable gases varies from…
