Abstract
Description
FIELD OF THE INVENTION
[0001] This invention relates to a hollow fiber membrane contactor for phase contact applications. The contactor is made from perfluorinated alkoxy polymeric materials, has a high packing density providing high useful contacting area, and the ability to operate with liquids of low surface tension. BACKGROUND OF THE INVENTION
[0002] Liquid-gas contactors are used to transfer one or more soluble substances from one phase to another. Examples of conventional contactors are packed towers, plate columns and wetted wall columns. In these systems, gas absorption of one or more components from a gas stream is accomplished by dispersing the gas as bubbles in packed towers and plate columns in a countercurrent flow to a liquid stream. Absorption efficiency is controlled apart from solubility considerations by the relative rate of the flows and the effective surface area of the gas flow bubbles. In wetted wall contactors the gas stream flows past a downward flow of liqui...
