Dynamic wetting head

Abstract

A dynamic wetting head with which polymers are prewetted and mixed. The prewetted and mixed polymers are typically used in the process of polymer flooding during chemical enhanced oil recovery. The dynamic wetting head comprises a prewetting unit and a mixing unit. The prewetting unit has a feed spigot provided in communication with a source of powder and projecting at least partially into a wetting chamber of the prewetting unit. The feed spigot feeds polymer powder into the wetting chamber. Furthermore, at least a first spray nozzle sprays water into the wetting chamber. The mixing unit comprises a mixing chamber with an inlet provided in communication with the wetting chamber outlet, a feed water inlet, and an outlet. A mixer is furthermore arranged within the mixing chamber.
