Abstract: The present invention relates to a method for detecting the presence of gas hydrates and/or ice in a medium. The method comprises at least the following steps:measuring at least at one measurement point in said medium two characteristic values of Raman spectra corresponding to two distinct vibration modes of the OH bonds of water, and determining the ratio π of said two characteristic values,determining the temperature T in said medium at said measurement point of said spectra,comparing ratio π with a value T0 corresponding to a predetermined threshold of formation of said crystals for said temperature T, anddetermining the presence or not of hydrate and/or ice crystals from said comparison.

Abstract: A method for measuring the concentrations of species present at at least one point of a separation unit operating in simulated moving bed (SMB) mode, or a hybrid separation unit employing a step for simulated moving bed (SMB) separation and a step for crystallization, by calibration by inline acquisition of Raman spectra for different mixtures; analysis by inline signal processing of the Raman spectrum.
