Naval Sea Systems Command Issues Submarines Life-Saving Lithium Hydroxide Curtains Developed by Battelle.Business Editors
WASHINGTON--(BUSINESS WIRE)--April 6, 2004
The Naval Sea Systems Command The Naval Sea Systems Command (NAVSEA) is the largest of the U.S. Navy's five "systems commands," or materiel organizations. NAVSEA consists of four shipyards, eight "warfare centers" (two undersea and six surface), four major shipbuilding locations and the NAVSEA headquarters, (NAVSEA NAVSEA Naval Sea Systems Command

It is a white hygroscopic crystalline material. It is soluble in water, and slightly soluble in ethanol. It is available commercially in anhydrous form, or as the monohydrate. curtains for the U.S. submarine force. By late 2004, every submarine in the fleet is expected to be outfitted with 400 of the new life-saving curtains. Developed and produced by Battelle, the lithium hydroxide curtain removes hazardous carbon dioxide carbon dioxide, chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. that can accumulate in the atmosphere of a disabled submarine, improving the crewmembers' ability to survive while awaiting rescue.
The curtain is a breakthrough, cost-effective solution that employs Commercial-off-the-Shelf (COTS) technology to enhance the reaction rate of lithium hydroxide, the carbon dioxide absorbing chemical already in use by the Navy's submarine force. First used by submarine sailors prior to World War II, lithium hydroxide crystals react with and absorb carbon dioxide that builds up in an enclosed environment. Stored in canisters on board all submarines, the crystals are used in hopper fans if power is available or spread out on bunks or the deck in the event of an emergency or power failure. Due to a caustic dust produced by spreading the lithium hydroxide crystals, this method is only employed as a last resort.
In late 2000, experts at Battelle, a global leader in science and technology, began searching for a more effective solution. The new Battelle curtain eliminates this concern and provides a safer means for carbon dioxide absorption using the current equipment.
"Following the sinking of the Russian submarine Kursk, a number of Battelle researchers - many former submariners themselves - recognized a critical need," recalled James Worthington, a Project Manager in Battelle's Equipment Development group and one of the four inventors of the lithium hydroxide curtain. "We were looking to develop a device that could use the existing supply of lithium hydroxide crystals to absorb carbon dioxide, while operating with little or no power to better protect sailors from the harmful dust."
Drawing from their own experience, the Battelle team developed the concept for the curtain, designed a prototype and submitted a proposal to the Navy to fabricate and test various prototype curtains. Following Battelle's initial tests, the curtains were tested by the Naval Submarine Medical Research Laboratory The Naval Submarine Medical Research Laboratory (NSMRL) is located on the New London Submarine Base in Groton, Connecticut. The laboratory's mission is to protect the health and enhance the performance of our War Fighters through focused submarine, diving, and surface (NSMRL NSMRL Naval Submarine Medical Research Laboratory (US Navy; Groton CT, USA) ) in Groton, Connecticut
"We were very supportive when Battelle came to us with the initial design for the lithium hydroxide curtain," said Michael Holmes Michael Holmes may refer to:
In March 2004, Battelle researchers - Cliff Dodson, Rod Jenkins, Mark Koenig Mark Koenig (July 19, 1904 - April 22, 1993) is a former shortstop in Major League Baseball. He played for 12 seasons from 1925-1936. He was the starting shortstop for the New York Yankees 1927 Murderers' Row team, and was the last survivng member of that legendary team. and Jim Worthington - received a patent for their resourceful design that uses a polypropylene-fabric to contain lithium hydroxide crystals. Resembling an air mattress, the curtain is made of five sealed channels that enable passive absorption of carbon dioxide while preventing lithium hydroxide dust from escaping and irritating the submariners' lungs and skin. Unlike previous methods of dispersing the substance, each 7.5-foot long curtain is lightweight, easily stored in the limited space of a submarine, and most importantly Adv. 1. most importantly - above and beyond all other consideration; "above all, you must be independent"
above all, most especially requires no electrical power to operate. In addition, this safety enhancing solution is inexpensive, costing only $19 per curtain.
There is also another significant, rather surprising, advantage to the curtain. With temperatures at the bottom of the world's oceans hovering just above freezing, hypothermia hypothermia

The heat produced by the chemical reaction of lithium hydroxide crystals absorbing carbon dioxide, can rise upwards of 140 degrees Fahrenheit, and be harnessed by the curtain. By lacing several curtains together using grommets along the edges of the fabric, sailors can create an enclosure which can provide a heat source.
The lithium hydroxide curtain will be on display from April 6th - 8th during the Navy League's Sea-Air-Space 2004 Conference and Exhibition at the Marriott Wardman Park Hotel in Hall A at booth #1800. For additional information, contact Katy Delaney at (614) 424-5544 or email@example.com.
