Abstract:

Drag reduction degradation characteristics of Separan AP30 are reported. A recycle tube flow experiment was used to investigate this property of drag reducing polymer solutions. Experimental pressure gradient and flow rate measurements were made as a function of time. From this data, friction factor- time plots on log-log coordinates were constructed, all of which exhibited three distinct regions which are discussed. Correlations are presented relating the process time in which maximum drag reduction exists, and the process time in which significant drag reduction exists, to the polymeric and system flow variables.
