Abstract
This invention comprises a device and method for producing and conveying a diphasic fluid. The method comprises mixing the gas with a liquid to produce a diphasic fluid which is forced into a pipe by diphasic fluid pumping means, the amount of the added liquid depending on the maximum value of the gas-to-liquid volumetric ratio of the diphasic fluid which can be processed by the pumping means. A further refinement is achieved by separating a portion of the liquid phase from the pressurized diphasic fluid and recycling it to the mixing stage. The device comprises means for mixing the substantially gaseous fluid with sufficient liquid to form a diphasic fluid having the predetermined gas-to-liquid for the pump. The means for mixing also includes means for equalizing the pressures of the gas and liquid prior to mixing and conveying through the pipe.
