摘要： A process treats production water resulting from enhanced oil recovery, the production water comprising an aqueous phase and an organic phase dispersed in the aqueous phase, and at least one polymer in the aqueous phase. The process includes:



a step of bringing said production water into contact with an additive comprising at least one tetrakis(hydroxymethyl)phosphonium salt (THMP salt),
a step of separating the aqueous phase and the organic phase of said production water comprising said additive, by means of a hydrocyclone.

An enhanced recovery process uses a step of treating the production water according to the invention.

摘要： 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 τ of said two characteristic values, determining the temperature T in said medium at said measurement point of said spectra, comparing ratio τ with a value τ0 corresponding to a predetermined threshold of formation of said crystals for said temperature T, and determining the presence or not of hydrate and/or ice crystals from said comparison.
