Abstract
14,230. Raschig, F. Oct. 26, 1912, [Convention date]. Progressive evaporators; hydrocarbon oils and tars; distilling. - Tar, mineral oils, and other liquids are continuously distilled by passage through a series of stills I, II, maintained at the same temperature but at successively reduced pressures. The liquid on its way from the still I to the still II passes through a receptacle c, which is of considerable height, and is fitted with an overflow n, so that, in case of a failure of the vacuum in the still II, the still I will continue to work, the undistilled liquid being discharged through the pipe n. The liquid entering through the pipe a is preheated by heat-exchange with the residual liquid leaving the still II by the pipe l. In distilling tar in steam-heated stills maintained at atmospheric pressure and under high vacuum respectively, ammonia, benzene, toluene and water are removed in the first still, and naphthalene, carbolic oil and creosote oil in the second still. When more than two stills are used, reducing- valves are arranged to provide the requisite gradual reduction of pressure between the first and last stills.
