Abstract
Method for analyzing the alkalinity conditions in aqueous liquids, comprising: sampling a known amount of the aqueous liquid and placing it in a container of known volume, measuring pH in the sampled liquid and pressure in the container, adding a known amount of CO2 to the sampled liquid, and measuring pH in the sampled liquid and the pressure in the container, and finally calculating the total alkalinity based on the values from the performed measurements. An apparatus for conducting the method is also described as well as a method for controlling chemistry of a glycol containing liquid in a system for recovery of glycol.
