Title: Process for the treatment of glauber's salt
Inventor: GRAFTON RAYMOND WILLIAM
IPC: B01J47/10
Filed: 1956-01-25
Abstract: <PICT:0801527/III/1> <PICT:0801527/III/2> Sodium sulphate, particularly that obtained as a bye-product in the viscose rayon industry, is dissolved in water and the solution treated with an ion-exchange resin to form sulphuric acid and a sodium resin salt, and the latter is regenerated with nitric acid to form sodium nitrate solution.  The cyclic process of the invention may be effected in a number of reactors arranged on a turntable which moves the reactors successively through a zone for effecting the first reaction, a washing zone, a regenerating zone with nitric acid, and a further washing zone.  Alternatively the cyclic process may be effected by providing a single rotary valve which connects various reactors to the correct liquor feed and withdrawal points at the appropriate stages of a cyclic process.  The first method is shown in Figs. 3 and 4.  Thus in Fig. 3 a series of fifteen reactors are arranged on a turntable which rotates in an anticlockwise direction.  As shown in Fig. 4, each reactor 1 mounted on the turntable 16 is provided with a lower inlet 20 from a gutter 18 fed by line 17 and an upper outlet 21 which passes into gutter 22.  The lower gutter 18 is formed into sections and the liquor flows from one section of gutter 18 through the reactor into the upper gutter 22 and from there to the next succeeding section of the lower gutter 18.  As shown in Fig. 3, four treatment zones are provided: in zone A the sodium sulphate solution passes successively through reactors 8, 7 and 6 and the resulting sulphuric acid solution is withdrawn between reactors 5 and 6.  As the reactors move anticlockwise and the liquor circulates clockwise the sulphuric acid displaces water in reactors 5 and 4 which had been fed to these reactors when they were in positions 2 and 3.  The water fed to reactor 2 displaces the nitric acid present therein and the dilute nitric acid so obtained may be recovered.  In zone C, nitric acid solution is fed successively through reactors 1, 15, 14 and 13 and the resulting sodium nitrate solution is withdrawn between reactors 13 and 12.  In zone D the water in the anticlockwise circulating reactors 11 and 12 is displaced by the sodium nitrate solution whilst washing water is fed to reactors 10 and 9, the effluent from the latter being dilute sodium sulphate solution.  A specific example is provided.  In the alternative embodiment with a fixed set of reactors and a rotary valve, a stator is provided with concentric spaced positions which make connection with the inlet and outlet of the individual reactors and to the supply and withdrawal pipes for the reactants, products and washing solutions.  The rotor, in spring-loaded connection with the stator, is provided with channels so that on the intermittent rotation of the rotor the various reactant feed pipes are connected to the appropriate points of the reactors in the cycle. In order to prevent crystallization of sodium sulphate, the free face of the rotor may be heated, for example by steam.
