Description

Tangential flow contactor element Cross-reference to related patent applications This patent application claims the benefit of U.S. provisional patent No. 63/539,358, filed 9/20 of 2023, the entire teachings and disclosure of which are incorporated herein by reference. Technical Field The present invention relates generally to a carbon capture element, and in particular to a laminated carbon capture medium for tangential flow contactor elements. Background For many years, reduction of carbon dioxide emissions has been an important environmental mission. Various promising techniques have been proposed to address the generation of carbon dioxide in various processes, including power generation and production of certain products. One emerging technology is carbon capture. During carbon capture, carbon dioxide is removed from the air stream of ambient air and the air stream having a reduced carbon dioxide concentration is released. The captured carbon dioxide is stored, preventing its release into the atmosphere.
