The static jar test was also used to provide information on the induction time for bulk precipitation which is important for identifying if the nucleation process for the surface deposition test in the bead pack is controlled by homogenous nucleation and growth in the bulk solution, heterogeneous...

.... Gypsum formation was inhibited for at least 6 hours and gypsum particles remained in a size of smaller than 200 nm for 12 hours in the combination of CMC and HDTPM. For calcite, measured induction time was 134 minutes and calcite particles were dispersed for at least 15 hours with its average particle...

.... Series of experiments were conducted in both batch reactor and flowing tube to investigate the range of supersaturation index (SI) where barite forms. In the batch experiments, a green laser apparatus was used to determine the induction time, which is defined as the time elapsed between the creation...

... of deposited barite is micrometer sized crystals. The highest deposition rate happens at the beginning of the tubing even before the expected induction time of bariums sulfate. The results indicated that the deposition happens even before the mixed solution is expected to form particles, which suggest...

...PTFE Tubing The induction time, or the time in which calcium carbonate deposition becomes detectable, was approximately 30 minutes ( Fig. 2a ). The time it took for steady state deposition to occur in the system shortened as the experiment progressed. At an initial flow rate of 150 mL/h...

... relationship between concentration of scale inhibitor and the logarithm of the induction time in the presence and absence of inhibitior is described in a previous paper ( Liu, Kan et al. 2014 ). A set of experiments was conducted to test the effect of Fe(III) on scale inhibitors at various experimental...

... is then measured via the method of standard additions, assuming a linear relationship between the scale inhibitor concentration and the logarithm of barite induction time. Seven different scale inhibitors, including phosphonates, carboxylates and sulfonates, were detected in two typical synthetic brines at low...

... surface. The data from the surface is presented in conjunction with the findings from bulk phase experiments. A small bore flow rig and a quartz crystal microbalance were used for monitoring the induction time and the real time deposition of CaCO 3 . Calcium carbonate deposition was examined at a range...
