This study numerically investigates hollow fiber membrane modules for gas purification. We found smaller fibers enhance purification but reduce overall separation performance, highlighting a critical trade-off.

Area of Science:

  • Chemical Engineering
  • Materials Science

Background:

  • Hollow fiber membrane modules are crucial for gas purification, leveraging selective permeation.
  • Process intensification aims to minimize retentate loss and gas pressure through scale optimization.

Purpose of the Study:

  • To numerically investigate gas separation performance at the fiber bundle scale.
  • To analyze the impact of fiber bundle configuration on overall module performance.

Main Methods:

  • Numerical investigation of gas separation performance.
  • Quantification of flow channeling and anisotropy effects using permeability tensor and Sherwood number.

Main Results:

  • Flow channeling and anisotropy significantly impact mass-transfer coefficients in different flow configurations.

  • A trade-off exists between purification efficiency and recovery rate.
  • Smaller fibers, while increasing surface area for purification, can hinder separation performance due to reduced penetration within bundles.

    • Conclusions:

    • Optimizing hollow fiber membrane modules requires balancing purification and recovery.
    • Understanding bundle-scale effects like flow channeling is key for module performance enhancement.
