Abstract
5552. Rosenblum, J. A., Rosenblum, G., Rosenblum, A., and Gottman, G. de, [trading as Rosenblum, D., (Firm of)], Brech, L., and Tyborovvski, E. March 6. Pulp, preparation of.-In a process for the manufacture of cellulose from green pine wood, fir, poplar, aspen, and other woods,straw, hemp, grasses,&c., advantage is taken of the fact that the use of solutions containing free ammonia enable a high pressure to be obtained at a comparatively low temperature. Ammonia is added to ordinary lye, or to calcium bisulphite lye in which case calcium monosulphite is precipitated and removed leaving ammonium sulphite and excess of ammonia. Ammonium salts and lime to free the ammonia may be used. Lyes containing little or no sulphurous acid may be regenerated by introducing sulphurous acid until slightly acid, and may be again used with ammonia, and after this second use may be further utilized for the treatment of straw before the ammonia and other valuable substances are recovered. In carrying out the process, the boiler K<1> is filled with wood and soda lye containing ammonia, and the pressure raised to 10-12 atmospheres, the cocks 3, 1, and 8 being closed. When the heating is completed, the free ammonia is driven off through the cooler C and absorbed in the tank A containing preferably cold water. The lye is then driven through the pipe b into the regenerator R’ with the aid of a pump if necessary. Aqueous or gaseous sulphurous acid is introduced through the pipe c and the precipitates collect at the bottom. The clear solution from the vessel R<1> and the absorbed ammonia from the tank A are run into the boiler K<2>, and a second lot of wood is treated therein. After heating, the ammonia is driven off and absorbed in the tank A, and the lye is pumped into the regenerator R<2>, where the combined ammonia is liberated with lime and the freed ammonia driven off by steam from a pipe g through a cooler C and the absorption tank A. The ammonia can be conducted from the tank A to the boiler K’ through the pipe i. Specification 2574/65 is referred to.
