Subsurface aeration wells

Migration forms of the same element differ primarily in their attitude to natural solvents. Polar compoxmds well dissolve in water, nonpolar - better in nonpolar solvents, volatile and gas - in the subsurface gas. Preferences of the migration forms towards different subsurface transporters may be evaluated by their distribution in various media imder identical thermodynamic conditions. Let us assume that in close to normal, for instance in the aeration zone, component i has to distribute between sweet-water, underground gas at a pressure 1 bar and nonpolar hydrophobic liquid, which have equal volumes, i.e., in equation (2.336) = 5 = 1.
