Method for measuring the mineralization of aqueous solutions in pipeline flows

Abstract

A description of the hardware–software complex designed and manufactured for the operational assessment of the concentration of a dissolved substance in a water stream on the lower surface of metal pipes in various technological lines without sampling is presented. At the Trofimuk Institute of Petroleum Geology and Geophysics SB RAS the dependences of the electrical conductivity of aqueous solutions on temperature were studied under specific conditions – in an electrically conductive cell. Physical experiments were performed using solutions of different mineralization (from 0.5 to 300 g/L), in a measuring cell made of steel of small volume (8.14 cm3). Mathematical modeling of solution mineralization assessment has been performed.
