METHOD FOR DIMENSIONING INDUSTRIAL PLANTS OR GAS-LIQUID DIPHASIC MIXTURE FLOWS IN INTERMITTENT REGIME

摘要

- Method for dimensioning industrial installations where a two-phase gas-liquid mixture flows intermittently. - The flow of each phase is modeled in a gas pocket and a liquid cap using models. physical. The flow of gas entrained behind a gas pocket is also modeled using a physical model. For this model, it is considered that the pressure variation between the back of a gas bag and a liquid plug behind this pocket is responsible for the drive, and a critical condition for forming the flow of the fuel is taken into account. entrained gas. The pressure losses within the pipe are then determined using an iterative method in which this entrained gas flow thus modeled is adjusted, with an average gas flow obtained by an intermittent flow conservation equation. established. We deduce the dimensions of the industrial installations which minimize the losses of loads. - Application to the transport of petroleum fluids and particularly to the dimensioning of the production lines, risers ...
