Abstract

A method of delivering transport fluid from an open port interface to an outlet via a transfer conduit includes delivering, to the open port interface, a transport liquid at a first flow rate. The open port interface is disposed in a pressure environment having a first pressure. A second pres-sure is applied at the outlet, wherein the second pressure is less than the first pressure. The pressure applied at the outlet generates a motive flow on the transport liquid, thereby drawing into the transfer conduit (a) the transport fluid, wherein the transport fluid is in contact with a wall of the transport conduit, and (b) a gas present in the pressure environment. The gas forms an air core within the drawn transport fluid. The air core extends substantially an entire length of the transfer conduit.
