COMBINATION OF POLYMER SLURRY TYPES FOR OPTIMUM PIPELINE DRAG REDUCTION |
摘要 |
<p>A method of extending or broadening the effective time of drag reduction for a drag reducing agent in a pipeline may be custom-designed by combining two drag reducing slurries or other drag reducing products made by different or alternative techniques. For instance a precipitation polymer slurry derived from polymer precipitation where the polymer dissolves relatively quickly can be combined with a ground polymer slurry derived by grinding bulk polymer (ground at either cryogenic or non-cryogenic temperatures), or by using other size reduction techniques, where the latter polymer dissolves relatively slowly. In one non-limiting embodiment of the invention, bulk polymer may be ground directly into a precipitation polymer slurry to make the ground polymer slurry and blend the slurries simultaneously, where the precipitation polymer slurry serves as an anti- agglomeration agent.</p> |
