Storage of Brine

Tank construction is not complex. The American Petroleum Institute s code API 650 is a commonly used standard, usually without a corrosion allowance. Tank bottoms have very gentle slopes, less than 1%, unless suspended solids are present. In that case, the slope may be greater and directed toward a flush or submerged drain nozzle. Where a heavy accumulation of solids is likely, tanks often have flush-bottom cleanouts. Not all tanks are covered. The likelihood of finding open tanks decreases as purity becomes greater and size of tank smaller. Where a roof exists, it is usually self-supporting. 

Smaller brine tanks usually are made of FRP. At least within the process, a good grade of corrosion barrier, for example a bisphenol-type resin, is recommended. Very small quantities of brine sometimes are stored in polyolefin tanks.

This project is of interest for several reasons, but primarily because the deep fluid is used as a closed loop, avoiding surface storage of brines, and because the seismicity induced by stimulation of the reservoir is continually watched in order to limit the risks. The Soultz-sous-Forets geothermal site could be a... 

Two concentric spheres are arranged to provide storage of brine inside the inner sphere at a temperature of — 10°C. The inner-sphere diameter is 2 m, and the gap spacing is 5 cm. The outer sphere is maintained at 30°C, and the gap space is evacuated to a pressure of 0.0S atm. Estimate the free-convection heat transfer across the gap space.

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. 

This review article summarizes the factors that influence the storage of C02 in deep aquifers. A case study of expected mineral-brine-C02 reactions in the Rose Run Sandstone, a deep aquifer and oil- and gas-containing formation in the Appalachian Basin area of eastern Ohio, USA, is presented. Geochemical reactions between C02, brine, and formation minerals are emphasized in the example because these reactions determine the ultimate fate of C02. 

This project placed encapsulated spent fuel elements from an experimental AEG reactor into storage holes drilled into the floor of the mine located in a salt bed. Valuable experimental information was obtained about the interaction between the waste form and the salt in which the waste was emplaced. It was in fact this experiment, conducted in 1968, which revealed that inclusions of moisture, or brine, in the salt beds have a tendency to migrate up a thermal gradient towards a heat source placed in the salt. Quantities of brine were measured as migrating to the deposited waste canisters and the interaction of this brine with the canis-tered material was observed. 

Any of the products of brine electrolysis, chlorine, sodium hydroxide, and hydrogen can be hazardous if released. When releases do occur, it is usually from process upsets or breakdowns, which may be minimized by the construction of fail-safe plants, proper maintenance, and by safe transport and storage practices. Probably of greater long-term concern is the mercury loss experienced through the process streams of a mercury cell chloralkali operation. These losses can also carry over to the products of the diaphragm cell, even though this does not use mercury, if a common brine well or common salt dissolver is used for both sets of cells. 

The horizontal ice distribution simulated with such a low order ice model resembles the observed distributions of sea ice however, the storage of freshwater in the ice and the formation of a new water mass by freezing with brine release and by melting is neglected. To include these features, the three-level ice model of Winton (2000) is coupled with MOM-3.1 to provide an improved representation of sea ice for long-term simulations. The sea ice is vertically resolved by two ice layers and a snow cover, with different development of thickness and temperature. As shown in Fig. 19.3, this local thermodynamic description yields arealistic simulation of the interannual variation in the thickness and the spatial extent of the ice cover in the Baltic Sea. The transfer of wind momentum to the currents and to surface waves is exponentially damped out if the ice thickness exceeds a critical value, for example, 10 cm, assuming fast ice.

In early 1976, we installed a Hypalon membrane liner for the storage of saturated brine at an Arizona gas terminal. The terminal is located above a salt dome used to store liquified butane and propane during the summer months, which is withdrawn during the peak use of the winter months. The pond measures approximately 405 X 580 X 40 feet deep and holds saturated salt brine to displace the liquified gas for withdrawal. 

The selection of a lining material is most Important. Leaks cause loss of brine, loss of heat, loss of insulation, and are potential environmental pollutants. The well documented history of the use of chlorosulfonated polyethylene for long term outdoor storage of saturated brine solutions makes it an excellent candidate.
