Membrane Contactor based CO2 Absorbing Module (MC-CAM)

In order to meet Navy’s need, ChromoLogic LLC (CL) proposes to develop a Membrane Contactor based CO2 Absorbing Module (MC-CAM) to timely remove CO2 maintain CO2 concentration of CCR in a safe range (<0.2%). It’s anticipated that MC-CAM system will be smoothly integrated to the current military SCUBA rebreathers providing endurance for over 10 hours. The end product will become standard CO2 scrubbing solution for all underwater operations. The high ratio of surface area to package volume, innovative microstructure, and application of novel catalyst enable the entire design to be compacted at least to 60% of the commercial canisters. Mainly based on physical absorption, the ruggedized MC-CAM is reusable and is supposed to protect divers from hypercapnia without any prevention maintenance. In Phase I, CL will fabricate a small prototype for the proof of concept. In Phase II, a high fidelity full size prototype will be prepared and demonstrated at Navy facilities.
