Abstract
Gas injected into a liquid flowing through a pipeline is sheared to increase the interfacial surface area by a shearing element which consists of an elongate body which can be placed directly inside the conduit, the element having baffles transverse to its center axis, the baffles being apertured with holes less than about 0.5 cm in diameter. In preferred embodiments, the baffles define a series of zig-zag flow paths which promote turbulent flow while also urging the gas bubbles into and through the apertures. The bubbles are thus sheared and agitated at the same time.
