Abstract
Un procedimiento para la fabricación de cristales substancialmente secos de sales de adición ácidas inorgánicas de urea, que comprende introducir en un tambor una solución o derretido de urea concentrada a una temperatura de entre aproximadamente 110s C y 132s C y un ácido inorgánico concentrado, usándose la urea y el ácido en cantidades substancialmente equimoleculares, y haciéndose que el tambor se agite e impulse la mezcla y la resultante sal de adición ácida inorgánica de urea hacia el punto de salida del producto, mientras que simultáneamente se pasa n gas caliente a través del tambor.A process for the manufacture of substantially dry crystals of inorganic acid addition salts of urea, which comprises introducing into a drum a solution or melt of concentrated urea at a temperature of between about 110s C and 132s C and a concentrated inorganic acid, using the urea and acid in substantially equimolar amounts, and causing the drum to agitate and propel the mixture and the resulting inorganic acid addition salt of urea toward the product exit point, while simultaneously passing hot gas through the drum .
