Separations

This method optimizes the existing distillation system and its heat-exchanger network simultaneously, lowering energy consumption and freeing up capacity at a minimum capital investment.

Ionic liquids have already moved into the commercial arena as reaction solvents. This article compares them to conventional solvents and examines their potential for the extraction of benzene, toluene and xylene from reformate.

Purifying high-value mixtures, such as pharmaceuticals, can be an expensive undertaking. Choosing the correct chromatography methods can improve purity and reduce processing time and cost.

Tangential flow filtration (TFF) is commonly used to concentrate and dialyze solutes. It generally involves the circulation of the feed solution over a filter surface. This article presents a brief overview of the principles governing TFF, and...

With solid-liquid equilibrium as its foundation, this systematic approach makes it easy to identify operating regions and theoretical yield to maximize the desired product.

Maintaining proper pressure can play a crucial role in the stable operation of a distillation column. Here’s how to select the most appropriate pressure-control scheme.

Previously, simulations based on nonequilibrium, or rate-based, models were considered impractical due to their complexity. However, with ever-increasing computing power, these simulations are not only feasible, but in some circumstances they should...

Use this new correlation based on window liquid velocity to predict baffle tray capacity.

Use phase diagrams to develop reliable crystallization processes quickly and cost effectively.

The flow fields in multiphase separators are often extremely complicated, making it difficult to model such systems. Computational fluid dynamics (CFD) and visual dynamic modeling (VDM) can be used together to overcome some of the challenges.
