Mixers for immiscible fluids

A mixer far mixing immiscible fluids comprising:

• a) a mixer housing defining a flow passage therethrough from a first fluid inlet to an outlet thereof, an upstream portion of the flow passage defining a main longitudinal axis;
• b) a second fluid inlet defined in the mixer housing downstream of the first fluid inlet in fluid communication with the upstream portion of the flow passage;
• and
• c) a mixer section including a pair of flow constrictions defined in a downstream portion of the flow passage each having a flow area smaller than that of the upstream portion of the flow passage for enhancing turbulent mixing of fluids introduced at the first and second fluid inlets, wherein each flow constriction defines a centerline axis that is offset with respect to the centerline axis of the other flow constriction.

A mixer for mixing immiscible fluids comprising:

• a) a mixer housing defining a flow passage therethrough from a first fluid inlet to an outlet thereof, the flow passage defining a main longitudinal axis;
• b) a second fluid inlet defined in the mixer housing downstream of the first fluid inlet in fluid communication with the flow passage and oriented at an angle with respect to the main longitudinal axis, wherein the second fluid inlet includes a swirl inducer for inducing swirl on fluids flowing through the flow passage;
• and
• c) a flow constriction defined in the flow passage downstream of the second fluid inlet having a flow area smaller than that of the flow passage upstream thereof for accelerating a swirling flow of fluids flowing through the flow passage to enhance turbulent mixing of fluids introduced at the first and second fluid inlets.
