Title: Process for the regeneration of ion exchangers
IPC: B01J49/00
Filed: 1952-10-20
Abstract: In an ion exchange process where during a loading period the reaction B1 I.  E + B2A2 --> B1A2 + B2 I.E takes place and during regeneration B2I.E. + B1A1 --> B2A1 + B1I.E., B1A1 and B2A2 representing soluble salts to be converted to B2A1 and B1A2 and I.E. signifying the ion exchanger, the regeneration of a series of columns of I.E. is effected by dividing the series into two groups, passing excess regenerating agent B1A1 successively through the columns of the first group to obtain a solution of B2A1 + excess B1A1 which is removed by crystallization or other means, and passing the remaining solution (largely B2A1), through the columns of the second group in succession to obtain pure B2A1 solution.  The amount of excess regenerating agent is determined from the equilibrium diagram relating the fraction. <FORM:0740549/III/1> on the exchanger and in solution during regeneration.  An example of such a diagram is provided.  The first column of the first group is completely regenerated and withdrawn, the first column of the second group becomes the last of the first group, and an unregenerated column is added to the end of the second group and the process repeated.  In the drawing Fig. 1 is a flow diagram of regeneration, the series of columns C1-dn being divided into two groups C1-Cm and D1-Dn. Ev and Cr are evaporator and crystallizer respectively.  The columns of both groups are loaded with B2 ions.  Excess regenerating agent B1A1 entering group c leaves as a mixture of B2A1 and excess B1A1, the latter being separated by evaporation and crystallization.  The remaining solution B2A1 by passage through the columns D which contain B2 ions, emerges as pure B2A1.  Column C1 when completely regenerated, is removed; D1 replaces Cm and an unregenerated new column is added at the end of group D. In order to ensure purity of the discharged B2A1 solution it is sometimes necessary to remove not only B1A1, but also a small proportion of B2 ions before passage to the second group.  This may be done by crystallization or by the addition of an ion A3 which gives an insoluble B2A3 compound which is precipitated.  The process is exemplified by the production of potassium chloride and calcium nitrate, the production of sodium nitrate by an analogous process and the production of magnesium chloride and potassium sulphate from magnesium sulphate and potassium chloride.  Specification 421,154 is referred to.
