  • Method for reducing pressure drop in the transportation of drag reducer
    Patent number: 4881566
    Abstract: Method for reducing pressure drop in a conduit carrying a viscous drag reducing material by injecting a lower viscosity liquid which is immiscible with the drag reducing material at the periphery of the conduit to form a flowing annular layer of such lower viscosity liquid thereby reducing the pressure drop in the conduit.

  • Method for improving the performance of highly viscous concentrates of high molecular weight drag reducing polymers
    Patent number: 4771799
    Abstract: High molecular weight viscoelastic polymers are dissolved by passing the polymer solution through a die which "beads" the polymer allowing the formation of very fine filaments which are drawn into the flow. The beading and flow rate are balanced to maintain constant fine filament formation.
