摘要： A method for generating and characterizing an emulsion. The method provides a Couette device having first and second cylindrical members that define an annulus between them. The second cylindrical member is rotatably driven with respect to the first cylindrical member. Two or more substances each in a non-emulsified state are injected into the annulus. The Couette device is operated in a first mode to generate an emulsion from the two or more substances. The Couette device is also operated in a second mode to measure various attributes of the emulsion.

摘要： A method for determining the concentration of asphaltenes in a solution is described. A model is first established for estimating the concentration of asphaltenes in a solution based on multiple samples of solutions of asphaltenes in the solvent in which the concentrations are known. The multiple samples have varying concentrations of asphaltenes. The diffusivity and relaxation time are measured for each sample using two-dimensional NMR. The ratio of diffusivity to relaxation time for each sample is then calculated. A linear equation is determined to fit the relationship between the ratio of diffusivity to relaxation time and the asphaltene concentration by weight for the multiple samples, thus creating the model. For a given solution sample for which the concentration of asphaltenes is desired to be determined, diffusivity and relaxation time are determined using two-dimensional NMR, and the ratio of diffusivity to relaxation time is calculated. This ratio is then used with the model, so that the linear equation can be solved for the asphaltene concentration in the given solution sample.
