Abstract
IN the manufacture of cordite, which, is the propellant used in practically all arfns in warfare, a mixture of nitrocellulose and nitroglycerin is incorporated with a “solvent,” consisting of ether and alcohol, and the doughy mass is extruded through dies to form the cordite strands. These are dried on trays in closed recovery stoves, where the solvent is evaporated in a current of warm air until only a small amount of volatile matter remains, which is finally expelled in drying stoves. The solvent-laden air may be treated in absorbers for the recovery of the solvents. The present report deals with the use of sulphuric acid, water, and cresol as absorbents, the last being found most satisfactory. The air and absorbent were brought together in a Whessoe scrubber, such as is used in gas works, and the solvent then expelled by distillation. Calculations dealing with the operation of the plant are given.
