On the phase transition of light oil products in pipelines
Thread Content
I am currently interested in analyzing the two-phase flow and phase changes within light oil pipelines after applying steam tracing, and I was wondering if there are any relevant materials available ?
As long as the pressure inside the tube is greater than the saturated vapor pressure, no phase change will occur. Each light hydrocarbon has its own saturation pressure-temperature chart. By knowing the composition of the light hydrocarbons in the pipeline and the maximum heating temperature, one can use this chart or graph to determine the saturation pressure of that hydrocarbon at that temperature. Ensuring that the pressure inside the pipeline is higher than this determined pressure will suffice
As long as the pressure is kept below the saturated vapor pressure of that oil, phase change will not occur
It is sufficient to ensure that the pressure is higher than the saturated vapor pressure of that oil; in that case, no phase change will occur. This situation should be avoided
