Abstract
Systems and methods of the present disclosure relate to a method for online monitoring, without the need for sampling and in real time, the precipitation of inorganic salts in aqueous streams related to the petroleum industry. A set of collected NIR spectra is correlated with data provided by FBRM through a mathematical (chemometric) treatment and mathematical models based on artificial neural networks combined with principal component analysis were employed to estimate the quantity and size distribution of particles precipitated over time. The application of these process analyzers helps to understand the formation and growth of inorganic salt particles from the produced water (rich in carbonates and sulfates), which can precipitate at different stages in oil production and transportation facilities.
