A novel apparatus is disclosed which comprises: (a) pumping means for injecting a fluid through a conduit means into an inlet pipe of a fluid mixing tank, (b) said fluid mixing tank comprising a plurality of compartments connected in series and in fluid communication with adjacent compartments in the series, and designed to provide for a horizontal flow of fluids from the first compartment to the last compartment in the series, (c) at least one compartment being equipped with one or more radial-flow impellers connected to a vertical shaft, and means for rotating such impellers at a rate designed to stir the contents of the compartment radially with high shear and prevent fluid stagnation, (d) at least one compartment being equipped with one or more axial flow impellers connected to a vertical shaft, and means for rotating such impellers at a rate designed to circulate the contents of the compartment vertically, (e) the inlet pipe being designed to introduce fluids into the first compartment, and (f) a means for withdrawing fluid from the apparatus through a discharge opening in the last compartment in the series. The new apparatus is particularly useful as a horizontal flow hydration tank to prepare aqueous viscous fluids for use as well treatment fluids. Hydratable polymers can be hydrated rapidly and consistently in real time. The apparatus is less complex mechanically and operationally than the compartmentalized vertical-flow tanks of the prior art, and it can be constructed as a mobile unit. |
