CARBON DIOXIDE REMOVAL BY IONIC LIQUID SYSTEM FOR MOBILITY

1.0 GENERAL

1.1 PURPOSE

This statement of work (SOW) defines the tasks and deliverables associated with the initial feasibility for application of the Carbon Dioxide Removal by Ionic Liquid System (CDRILS) to a space suit life support system with the permutation referred to as Carbon Dioxide Removal by Ionic Liquid System for Mobility (CDRILS-M).

1.2 BACKGROUND

Carbon dioxide (CO2) and humidity control are essential features of the Extravehicular Mobility Unit (EMU) Portable Life Support Subsystem (PLSS). The PLSS for past EMUs such as the Shuttle and International Space Station (ISS) EMUs as well as the Exploration EMUs (xEMUs) have used solid adsorbents for CO2 and humidity control.

Carbon Dioxide Removal by Ionic Liquid System (CDRILS) utilizes a continuously recirculated ionic liquid sorbent and hollow fiber membrane contactors for CO2 removal from spacecraft cabin air. For the vehicle Environmental Control and Life Support System (ECLSS) application, CDRILS is undergoing development for a flight demonstration on the International Space Station (ISS) in 2028. As an extension of the approach used for CDRILS in the ECLSS application, Honeywell and the NASA Space Suit & Crew Survival Systems Branch are exploring a variation of CDRILS as the CO2 and humidity removal technology for the NASA Mars Exploration EMU (mxEMU) concept referred to as Carbon Dioxide Removal by Ionic Liquid System for Mobility (CDRILS-M). The continuous removal, liquid based CO2 and humidity control approach for a Mars Exploration application such as the Mars Exploration Extravehicular Mobility Unit (mxEMU) include:

Non-venting EVA capability in which H2O and CO2 captured in the sorbent are not vented into the environment during EVA o This enables recovery of these constituents back into the cabin ECLSS processing loop.

o The environment being explored by EVA capability receives reduced contamination loading

Inclusion of trace contaminant removal in the sorbent without need for a separate consumable component to perform that function

Improved long duration mission serviceability o Liquid sorbent can be changed out or replaced as part of maintenance without the overhead that would be present for replacing an existing state of the art scrubber such as the Metal Oxide canister (~32 lbs) or Rapid Cycle Amine (~16 lbs) using smaller or more discrete components.
