Abstract
The present invention is directed to a polymer dissolution system comprising a mix tank, a strainer, and a pump. The mix tank is configured to receive polymers, water, and an inlet stream, to form a polymer solution including swollen polymers, and to discharge the polymer solution. The strainer is configured to receive the polymer solution, and to withdraw at least a portion of the swollen polymers therethrough substantially without shear degradation, thereby forming a resultant solution, wherein the swollen polymers are dissolved at least in part. The pump is configured to receive the resultant solution, and to return the resultant solution to the inlet stream. In some embodiments, the strainer and the pump cooperate together to maintain a viscosity of the resultant solution substantially within a predetermined range.
