Carbon dioxide underground containment

A few years later carbon dioxide was injected into an underground tank containing Jet fuel as a tryout of a fire-fighting system. The tank blew up, killing 18 people who were standing on top of the tank. In this case the discharge may have occurred from the cloud of carbon dioxide particles. 

Some chemical reactions proceed very slowly, others with explosive speed, and still others somewhere in between. The dissolving of underground limestone deposits by water containing carbon dioxide to form caverns is an example of a slow reaction it can take centuries. The explosion of TNT is an example of a very rapid reaction. 

The effect of gas solubility on the rate of foam destruction is of major practical importance. For example, in the production of firefighting foams for underground use in coal mines, it is advisable to use exhaust gases as a disperse phase. However, they contain a considerable amount of carbon dioxide and water vapour that sharply decrease the expansion ratio and stability of the foam produced. 

This process and its reverse account for the formation of limestone caves and the stalactites and stalagmites found there. The acidic water (containing carbon dioxide) dissolves the underground limestone deposits, thereby forming a cavern. As the water drips from the ceiling of the cave, the carbon dioxide if ->st... 

There are numerous natural underground cavities, such as caves in limestone formations, which might conceivably be used for the containment of carbon dioxide, although there is always the risk that pressurized gas will leak out... 

Many of the chemical reactions that take place within us and around us involve substances dissolved in water. Nutrients dissolved in blood are carried to our cells, where they enter into reactions that help keep us alive. Automobile parts rust when they come into frequent contact with aqueous solutions that contain various dissolved substances. Spectacular limestone caves (Figure 4.1 ) are formed by the dissolving action of underground water containing carbon dioxide, C02(aq) ...
