Special Issue Information

Dear Colleagues,

Three-dimensional printing is an additive manufacturing process able to create three-dimensional objects from digital files. The objects may have shapes of different complexities, and their physical form is produced by adding layer after layer of a particular material.

The market of 3D printing has been experiencing an impressive growth with application in areas such as the automotive, aerospace, medical, and food industries. Today, several techniques are available—stereolithography (SLA), selective laser sintering (SLS), and fused deposition modeling (FDM) are typical examples—and different types of materials can be used, namely polymers, metals, glass, ceramics or even sugar and chocolate. Three-dimensional printing has crucial benefits over conventional manufacturing processes, such as highly efficient use of energy and resources with almost zero solid residual waste and a much larger freedom to design objects tailored to specific needs and goals.

Separation and reaction units are at the core of many industries, and their performance/enhancement are crucial to achieve more economic sustainable and environmental-friendly processes. In this context, the combination of proper modeling approaches with the flexibility of 3D printing can have an important and disruptive role on how these units are designed.

This Special Issue on “3D Printing in Separation and Reaction Processes” aims to address the recent developments and progresses achieved by the application of 3D printing to separation and reaction units/systems (from micro to macroscales). We welcome review articles and original research papers of a fundamental, numerical, or experimental nature. Topics include but are not limited to:

  • Membrane separation modules
  • Adsorption processes
  • Chromatography
  • Crystallization
  • Extraction processes
  • Multiphase catalytic reactors
  • 3D printing of structures for catalysis and adsorption
  • Reactor intensification
  • Flow hydrodynamics in process units
  • Scale-up strategies
  • Bubble removal
  • Rheology in 3D printing
  • Microstructured reactors
  • Microfluidic devices
  • 3D printing and organs on chip
  • New emulsification devices
  • Cell enrichment

The geometrical parameters of annular centrifugal contactors (ACCs) have an important influence on the extraction efficiency. The present work used a home-made 25 mm ACC constructed by 3D printing to investigate the effect of five geometrical parameters on the extraction efficiency. These parameters are annular width (d), clearance height (Hc), rotor inlet diameter (Din), bottom vane number (N), and the bottom vane’s bending direction (S). Central composite design was employed to design the experiment, and the response surface methodology was used to analyze the data. The results show that Hc and Din were positive for efficiency, while d and N were negative. When the bottom vane’s bending direction was the same as the liquid helical flow direction, the efficiency improved compared to the straight vane. It is found that 3 mm d, 5 mm Hc, 6 mm Din, and four clockwise covered vanes are the parameters where the efficiency reached the highest point of 94.5%. We analyzed the interactions between the parameters based on the coefficients of the quadratic equation, and the interactions were not considered in previous studies. This work surprisingly reveals that the effects of the parameters on the extraction efficiency were not independent, and there were interactions between the parameters. The interaction between the rotor inlet diameter and annular width was significant and could not be ignored. These results could serve as a reference for optimizing extraction processes and the design of ACCs. Full article
