摘要

The theoretical background for the design concept phase of the investigation of oil-liquefied natural gas slurry pipeline operation is presented. Because the pipeline is to be a cryogenic system,the heat transfer from the surroundings,from pumping inefficiencies,etc. to the flowing liquid is very important. In addition to heat transfer,pressure drop and pumping requirements are crucial to pipeline design. For slurry flow,there exists an increased pressure drop due to the presence of the solid in the liquid. Prediction and modeling of this pressure head loss phenomenon as a function of flow,solid particle and pipe characteristics and concentration is largely heuristic and heavily dependent on experimental verification. The problems that arise with respect to the flow in pipelines of homogeneous or of heterogeneous (two phase) mixtures of solids and conveying liquids are addressed. These problems must be solved in order to determine pipe diameter,transport velocity,solids concentration and head losses,and hence power requirements. The partially separable problem of heat gain and cooling requirements is also addressed for this particular cryogenic oil-liquefied natural gas application.
