ABSTRACT:
Apparatus, and method, for controlling the flow of dilute solutions of polymers such as dilute aqueous solutions of partially hydrolyzed polyacrylamides without causing any significant degradation of the polymer comprising the solutions. In one embodiment, the apparatus comprises a needle valve positioned in a conduit for transporting polymer solutions, and across which a fluid pressure differential exists. In another embodiment, the apparatus comprises a self-adjusting flow regulator which incorporates a tapered, or pointed, throttle carried on a reciprocatable piston.
