Recalculation of Carbon Dioxide Scrubbing Capacity of Battelle Curtains: Implications for Disabled Submarine Survivability Lithium Hydroxide Load Out Requirements. And Addendum to NSMRL Technical Reports No. 1228 of 27 August 2003 No. TR-2009-1270 of 12 August 2009

Abstract

This document is a response to Naval Surface Warfare Center Philadelphia Detachment (NSWCPD) Code 416 Comments on Naval Sea Systems Command (PMS-390) Proposed Alteration and Improvement (A and I), Partial Replacement of Granular lithium hydroxide (LiOH) Canisters and LiOH Curtain Kits with ExtendAir Canisters and ExtendAir Deployment Kits in the Forward Compartment of SSN 688 Class Submarines. This document is also intended to serve as an addendum to Naval Submarine Medical Research Laboratory (NSMRL) technical reports TR1228 and TR--2009-1270. The A and I is proposed to correct the inconsistency in the published carbon dioxide (CO2) absorption effectiveness of granular LiOH as used in Battelle Curtains. For only the forward compartment of the Los Angeles Class the value used was 0.85 lbs. of CO2 absorbed per 1.0 lb. of LiOH. For all other classes of submarines and all other compartments the value used was 0.75 lbs. of CO2 absorbed per 1.0 lb. of LiOH. This report reviews the methodologies and calculations used to derive the effectiveness of granular LiOH in order to elucidate the source of the inconsistent published values. The original 0.75 lbs. of CO2 absorbed per 1.0 lb. of LiOH capacity calculations in the NSMRL Technical Reports was found to be correct; however, additional data analysis steps were required to complete the analysis and reach values that are consistent with the 0.85 lbs. of CO2 absorbed per 1.0 lb. of LiOH reported by NSWCPD and used in the original determination of LiOH required for the Los Angeles Class. Based upon our reanalysis, NSMRL believes the subject A and I is not necessary for Los Angeles Class Submarines to meet the seven-day passive survivability.
