Abstract
Abstract An inlet piece for a pipeline for the transport of a viscous liquid surrounded by an annular layer of a liquid with a lower viscosity, which liquids are entirely or substantially insoluble with respect to each other, composed of a first chamber, provided with at least one inlet and with an exit for the viscous liquid, a second chamber, provided with at least one inlet for the liquid with a lower viscosity and with an annular outlet for that liquid which is so positioned as to surround the exit for the viscous liquid, and a rotation-symmetrical connecting piece for the connection to the pipeline; and a process for the transport of those liquids through a pipeline.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
141 words
Apparatus for transporting a viscous oil through a pipeline by the introduction of a surrounding annular layer of water about the oil without the occurrence of oil drop formation within the water layer, comprising, a first chamber bounded by two flat walls and a curved wall having two opposed oil inlets, one of the flat walls having a circular exit for the oil with a perforated plate located therein, a second chamber next to the first chamber which is bounded on one side by the flat wall in which there is the oil exit and on the other side another wall, the second chamber being provided with a water inlet and having an annular water outlet which surrounds the circular oil exit, and a cylindrical connecting piece attached to the water outlet of the second chamber and connected to the pipeline.
