This disclosure relates to a processing that includes a first shell and a second shell disposed within the first shell. The second shell includes a first end, a second end, and a wall extending between the first end and the second end. The second shell also defines a cavity and a longitudinal axis extending between the first end and the second end. A cross section of the second shell transverse to the longitudinal axis includes a first arcuate inner wall portion having a first radius of curvature and a second arcuate inner wall portion having a second radius of curvature. The first radius of curvature is larger than the second radius of curvature.

An apparatus for enhancing phase contact and chemical reactions is provided. The apparatus comprises at least one high-turbulence mixing stage and at least one high-shear-stress and high-cavitation stage. The stages are adapted to cause an increase in relative sliding speeds of phases involved in a multiphase flow passing through the stages. The high-shear-stress and high-cavitation stage comprises a rotor having radial teeth housed in a cavitation chamber surrounded by a stator having radial teeth. The facing surfaces of the radial teeth have a parabolic profile in circumferential direction. For each tooth, the parabolic profile lies along a curve of a parabola of which a vertex is arranged at a rear edge of the tooth, with respect to a direction of rotation of the rotor, and along a radius extending from the rear edge to a center of the rotor. The focus of the parabola is also located on the radius.
