Abstract

159,465. Lunt, G. P. Feb. 25, 1920. No Patent granted (Sealing fee not paid). Volatile liquids, recovering.-Relates to a process for removing solvent from nitrocellulose explosives or other colloid substances such as indiarubber by means of an inert gas circulated in a closed circuit, in which the vapour of the solvent is removed from the gas by a spray of the solvent, or one of the constituents thereof, in a liquid form, or of a liquid in which the solvent is soluble, and consists in controlling the amount and proportions of the different constituents of the solvent condensed by regulating the temperature and volume of the condensing-liquids, so that evaporation takes place at a rate equal to that at which the solvent diffuses through the colloid, thus avoiding " blistering." The colloid is placed on sliding shelves b in a chamber a heated by hotwater pipes r, s. Dampers m, n are provided for cutting the chamber out of the circuit while it is being recharged, and an outlet o is provided with a damper p whereby air can be displaced when a heavy gas, such as carbon dioxide or sulphur dioxide, is used in the circuit. The gas is circulated by a pump k and passes through a condenser d, provided with jets e of the condensing liquid, and a baffle g for catching the spray.
