Abstract
Plug flow through a series of tanks in fluid communication is effected by the addition of radial flow impeller means to at least one of the tanks. Plug flow through the tanks allows for sufficient residence time in the series of tanks to effect complete hydration of a hydratable gel for using in well treatment operations such as fracturing, acidizing and gravel packing.
