摘要

A method to reduce the Fall of pressure associated with the Turbulent Flow of a Fluid of low molecular weight through a Pipe.Comprising: introducing a Polymer Drag reducer in the Fluid of low molecular weight to form a mixture comprising a fluid and a low molecular weight Polymer Drag Reducer; steaming the mixture Fluid comprising a low molecular weight Polymer and a Reduct Or drag it into a bowl of steaming.Where the container contains Liquid Vaporization of high molecular weight Soluble in the mixture and comes into contact with the mixtureIn such a way that the Fluid enters a low molecular weight liquid gas phase and that of high molecular weight remains in a Liquid Phase; to isolate the polymer Drag Reducer is in the liquid of high molecular weight of the mixture comprising a Fluid of low weight Molecular and Polymer Drag Reducer to form (i) a liquid with high molecular weightThe Drag Reducer and (ii) a Steam of low molecular weight substantially free of Drag Reducer; and the low molecular weight regain Steam Vaporized substantially free of Drag Reducer.Also described is a method for Separating a Polymer Drag Reducer of a Fluid of low molecular weight, comprising: introducing a mixture comprising a fluid and a low molecular weight Polymer Drag reducer in a bowl of steaming.Where the container contains Liquid Vaporization of high molecular weight Soluble in the mixture and contact the mixtureSo the Fluid of low molecular weight between a gas phase and the liquid of high molecular weight remains in a Liquid Phase; steaming the mixture to spray the Fluid of low molecular weight in the container of Vaporization; Said Polymer Reducer to isolate Rrastre Said Fluid of low molecular weight (i) to form a Fluid of low molecular weight substitutionIalmente free Drag Reducer and (ii) a Liquid comprising a high molecular weight Polymer Drag Reducer; Steam and recover the low molecular weight substantially free of Drag Reducer.
