MONOETHANOLAMINE KEEPS THEM BREATHING PURE AIR The U. S. Navy is using monoethanolamine in atomic submarines to remove carbon dioxide from the air supply. There is about 5-6 vol. % C0 2 exhaled by humans, and monoethanol­ amine must keep the C0 2 level at less than 1% for a full crew of 100 men. This is accomplished with a scrubbing system in which the carbon dioxide is absorbed on contact with an ethanolamine solution. The acid gas is subsequently stripped from the solution for disposal at leisure. This carbon dioxide problem is unique with atomic submarines because of their ability to stay submerged for long periods of time, and apparently does not exist with con­ ventional subs that stay below for relatively short periods. There would appear to be similar applications in Civil Defense bomb shelters, and eventually in manned satellites. Jefferson technologists are particularly com­ petent in the science of gas treating. We have supplied ethanolamines and glycols, as well as technical services in depth, to major gas and refinery stream processors for many years. But, perhaps you are more interested in making a good shampoo, or one of the hun­ dreds of other applications for mono-, di- or triethanolamine, rather than purifying the air in an atomic submarine. Whatever your application, you'll find high specification products and helpful technical services at Jefferson. Try us . . . Jefferson Chemical Company, Inc., P. O. Box 53300, Houston, Texas 77052.
