Brine storage

Brine-Compensated Storage As the stored product is pumped into the cavern, brine is displaced into an aboveground brine storage reservoir. To withdraw the product from the cavern, brine is pumped back into the cavern, displacing the stored hquid. This method of product transfer is termed hrine-compensated, and caverns that operate in this fashion remain hquid-filled at all times. Figure 10-191 illustrates brine-compensated storage operations.

Brine from the top of the clarifier overflows by gravity to the clarifier pump tank. A turbidity meter in this line can monitor the solids content and provide an alarm in case of an upset in the clarifier operation. Again, operation and control are similar to those discussed in connection with brine saturation. The top of the tank should be at least as high as the top of the clarifier overflow system. This provides more brine storage capacity as well as time to correct a pump failure or other simple operating problems. The normal level in the pump tank is about 50%. Level control options are as in Fig. 11.3 ... 

C. Pure Brine Storage. The pure brine tank (Fig. 11.9) is a large vessel intended for the storage of brine to be fed to the cells. It can also be used to flush the cells upon failure of the rectifiers if there is no separate head tank for that purpose. This feature does not appear in the drawing. 

Orange, lemon, grapefruit, and citron peel is improved in quality if it is stored prior to candying in a salt solution containing added SO2. Uniformity and translucency of color and texture is markedly improved by sulfite-brine storage in comparison with fermentation in a dilute brine. This was found particularly true of citron (Cruess and Glickson, 1932 Fellers and Smith, 1937).

Most commonly, diaphragm cells are supplied with well brine on a once-through basis. The treated well brine flows to the treated brine storage tanks, which usually have 12-h capacity. From there the brine is fed to the cell room. The flow to each individual electrolyzer is controlled by a rotameter. If the flow of brine to the cells is suddenly disrupted by failure of the brine feed pump, the rectifiers automatically shut down since an inadequate supply of brine to the cells is potentially unsafe. The specifications for brine for diaphragm cells are given in Table 13.
