CALCULATIONS PREDICT CONDENSATE MOVEMENT AT T JUNCTIONS

A model for the prediction of the route preference of condensate at T junctions in gas-transportation pipelines has been developed. The double-stream model can be applied to sharpedged and radiused, regular, and reduced T and Y junctions. The model permits an understanding of condensate behavior at a junction. From this knowledge, precautions can be taken to install gas-liquid separators at those pipeline sections where condensate accumulates. Such accumulations may cause problems in gas-fired appliances or may damage delicate instruments in gas control and compressor stations.
