Features

Pushing the Boundaries of Process Intensification

In this special section, we continue last year’s theme to present new applications of modular chemical process intensification beyond its traditional area.

Ultrasonic Separation in Bioethanol Refining

Ultrasonic separation opens new possibilities for liquid-liquid separation due to its high energy efficiency and lack of phase equilibrium constraints.

Membrane Solvent Extraction to Recover Rare Earth Elements

Membrane solvent extraction provides an energy-efficient and environmentally friendly process to recover rare earth elements from electronic waste.

Process Intensification in the Pulp and Paper Industry

Process intensification techniques can improve the yield and overall efficiency of the kraft chemical pulping process.

Additive Manufacturing to Improve Cryogenic Air Separation

Additive manufacturing enables the construction of internal structures that can intensify and improve processes such as cryogenic distillation.

Special Section: Process Intensification

The articles within this special section cover topics as diverse as bioethanol purification, recovery of critical materials, pulp and paper processing, and air separation.

Inferential Models Using Vapor-Liquid Equilibrium Equations of State

Vapor-liquid equilibrium properties, such as dew point and enthalpy, can be more indicative of plant performance issues than raw online measurements.

Site Selection and Buffer Zone Maintenance

Establishing and maintaining buffer zones as additional space between the community and hazardous operations is essential for risk management.
