Tech Brief: Membrane Degassing And Debubbling Of High Viscous Fluids With Liqui-Cel® And SuperPhobic® Membrane Contactors
Increased gas content often leads to problems with bubble formation in highly viscous fluids. Membrane Contactors can provide an in-line and simple solution for improving processes by removing the bubbles from viscous liquids before they create a problem in a process operation. Membrane Contactors provide a very compact and efficient solution to the problems caused by bubbles.
Liquid is introduced to the outside of the hollow fiber membrane while a vacuum is pulled on the inside of the membrane; this facilitates the removal of gasses from the liquids that are in contact with the outside of the hollow fibers.
The hollow fibers are knit into a fabric array which is wrapped around the center tube. A high packing density provides a large membrane area that gives enough contact time to deaerate the liquid to low gas levels.
4x13 and 4x28 Liqui-Cel® or SuperPhobic® Contactors in Stainless Steel housings that utilize our patented Extra-Flow baffle are ideal products for this application. The baffle design forces fluid to travel in a radial flow path that is perpendicular to the hollow fiber membrane. This patented baffle increases contact area and improves degassing efficiency.
