Process Intensification in Gas–Liquid Mass Transfer by Modification of Reactor Design: A Review

Process intensification is one way of developing new efficient production pathways for the chemical industry to overcome the increasing global energy demand and solve global energy and environmental problems. Process intensification plays an important role in the gas–liquid mass transfer processes. Herein, an overview of the development in gas–liquid mass transfer enhancement is provided. Classical mass transfer models such as two‐film theory, penetration theory, and surface renewal theory are analyzed. Major enhancement methods, namely, mechanical modification of reactor, are summarized and discussed here. The most recent accomplishments in gas–liquid mass transfer engineering are also provided. This review is expected to inspire new research on gas–liquid mass transfer engineering to enhance the future development and potential applications of gas–liquid mass transfer in scientific and industrial fields. Suggestions for the enhancement of gas–liquid mass transfer are also provided.
