Model studies thermal effects of liquid pipeline colocation

05/14/2007
Changes in the vertical relative position of two liquids pipelines laid in the same trench (one crude, one products) produce only small changes in the temperature of the crude oil, allowing this approach to be used as a viable alternative to dual trenching. Small buried delocalization is acceptable and the relative position of the two pipelines can be determined by the small thermal change which occurs.This article uses a numeric model based on China’s West Pipeline to demonstrate the viability of pipeline colocation.West PipelineChina saved money and minimized environmental damage during the 2005 construction of the West Pipeline by laying several hundred kilometers of crude and pr...
