Four Battelle Curtains. Lithium hydroxide (LiOH) canister used in the Lunar Module Environmental Control System. Lithium Hydroxide (LiOH) canisters have long been a staple of CO₂ scrubbing in manned space vehicles. The LiOH canister can only be used once. Also known as a carbon dioxide absorber element, or scrubber. The LM's internal stock of LiOH canisters was not sufficient to support the crew until return, and the remainder was stored in the descent stage, out of reach. The design of the BC incorporates two innovations to reduce dust release: Figure 1. The LM ECS could use the LiOH canisters made for the LM (primary) as well as fitting the LiOH canisters made for the suit backpacks (PLSS) (secondary). The larger Primary canister had a capacity of 41 person-hours while the smaller, Secondary canister, identical to the canisters used in … The RPC strips can be supplied rolled up in a canister, as illustrated in Figure 3, which shows the rolled sheet as used in a diving re-breather set or as preformed sheets. A LiOH canister is, for the most part (a fan is used as a booster), a passive system. LiOH is currently used as the exclusive scrubbing method for Space Shuttle (STS) operations and as a contingency aboard the International Space … hydroxide (LiOH), which is an efficient CO 2 absorbent. The Russian Segment of the ISS includes LiOH (Lithium Hydroxide) canisters in its carbon dioxide removal system. The LiOH is bound in a polymer, which makes up the remaining 3% of the RPC and allows it to be formed into strips. The CM had an adequate supply of canisters, but these were incompatible with the LM. If the command module can be kept at least partially operational than the air filtration system can be kept on, so there is no need to jury-rig the LM system to take CSM LiOH canisters. Each curtain is attached to a conventional canister of LiOH, and the contents of the canister have been poured into the curtain. However, the MetOx canister requires a 14-hour regeneration bake-out cycle with an extensive amount of … The BC utilizes LiOH from the canister currently procured by the Fleet (i.e., manufactured per MIL-L-20213E). The MetOx can be used again. As I understand it, an adapter was made for contingency use on later flights. I don't know if the Apollo 13 crew had already used the PLSS LiOH canisters when the fix was developed. Contains lithium hydroxide to absorb carbon dioxide, and carbon to remove odors from the cabin air (see cutaway view). The canisters each contained beds of lithium hydroxide (LiOH) for carbon dioxide removal and beds of activated charcoal for odor control. The idea was that the redesign used from Apollo 14 onwards would prevent the total loss of CSM oxygen that necessitated the shutdown on Apollo 13.
