Designing hollow‐fiber contactors

Abstract

Abstract Hollow‐fiber contactors can provide fast mass transfer without flooding or loading. They are a promising alternative to packed towers for gas treating, and to centrifugal extractors for liquid‐liquid extraction. Hollow‐fiber contractors can be designed effectively using the mass transfer correlations reported in this paper. The correlations, based on aqueous deaeration and carbon dioxide absorption, are similar to earlier heat and mass transfer correlations, but can be complicated by diffusion across the fiber wall and by alterations in fiber geometry.
