Abstract
The invention relates to a method and to apparatus for thermodynamic analysis of a mixture of fluids, in which the volume of a sample of a given quantity of said mixture is caused to vary step by step and in monotonic manner, and the pressure of the sample is read at each step, the sample being stirred at each step so as to hasten the mixture reaching thermodynamic equilibrium. According to the invention, the sample is stirred by applying ultrasound to said sample by means of transducer ( ). The sample can be contained in a bag ( ) of flexible material immersed together with the transducer in a control fluid inside a rigid container ( ). The invention can be used to determine the bubble point of a mixture of hydrocarbons.
