METHOD FOR REDUCING PRESSURE DROP IN THE TRANSPORTATION OF DRAG REDUCER |
| 摘要 |
<p>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.</p> |
