Models mixing during precipitation

Recent work identifies mixing during precipitant addition as a determinant of aggregate physical properties such effects are described with a floc-strength model. 

Al-Rashed etal. (1996) and Al-Rashed and Jones (1999a,b) presented a CFD-based model to predict the effects of mixing during batch-wise gas-liquid reactive precipitation in the flat interface cell used by Wachi and Jones, 1991b. A 2D flow simulation was developed for the chemical reaction with... 

Fig. 30.1. Volumes of minerals precipitated during a reaction model simulating the mixing at reservoir temperature of seawater into formation fluids from the Miller, Forties, and Amethyst oil fields in the North Sea. The reservoir temperatures and compositions of the formation fluids are given in Table 30.1. The initial extent of the system in each case is 1 kg of solvent water. Not shown for the Amethyst results are small volumes of strontianite, barite, and dolomite that form during mixing.
