Device that can be used in an enhanced oil recovery method by injection of a solution of water soluble polymer and brine having a viscosity below 1000 cps that includes a mixer, and preferably a static mixer, capable of homogenizing the solution on-line; a device capable of measuring the viscosity of the homogenized solution, continuously, downstream of the solution injection pump, at a pressure below or equal to 250 bars, and preferably between 50 and 250 bars, and at a temperature below or equal to 120&#xb0; C., and preferably between 40 and 120&#xb0; C., by measuring a pressure drop in a calibrated tube, at a constant rate of flow.

Device for measuring and controlling on-line viscosity at high pressure

This invention involves a process for reducing friction in ethanol during its transport through pipelines. This process involves combining ethanol with a polymer-based composition, characterized in that the polymer is obtained from at least 50 mol % of at least one monomer selected from the group comprising N-substituted acrylamides, N-substituted methacrylamides, N,N-substituted acrylamides, N,N-substituted methacrylamides, substituted acrylates and substituted methacrylates.
