摘要： Method for preventing hydrocarbon based deposition in a multiphase fluid mixture flowing in a pipe section, said mixture being susceptible to the formation of hydrate and wax under given thermodynamic conditions, comprising:
- flowing the multiphase fluid mixture (13) in a pipe section (21) having a measurement section (22);
- irradiating the multiphase fluid mixture (13) flowing into the measurement section (22) with a radiation having a spectrum comprising at least three distinct energy levels;
- measuring (S11) the attenuation of the radiation transmitted through the measurement section (22) of the multiphase fluid mixture (13);
- estimating a solution triangle and an operating point (OP) based on said attenuation measurements, said solution triangle comprising an oil apex (AP O ) and a water apex (AP W );
- measuring a differential pressure of the multiphase fluid mixture in the measurement section (22);
- repeating over time the attenuation and pressure measurement steps, and solution triangle and operating point estimation step;

wherein the method for preventing hydrocarbon based deposition further comprises:
- detecting over time a shift of the operating point towards said oil or water apex in dependence on the hydrocarbon based deposition;
- detecting over time whether a variation of the differential pressure is outside a differential pressure range, respectively; and
- initiating at least one prevention measure (S13, S16) when detecting a correlation between said shift of the operating point (OP) towards oil or water apex and the differential pressure being outside the differential pressure range (S12, S14, S17).
