At higher temperatures, the solubilities of the minerals were lower, but now the reactions rates were higher, so similar effluent concentrations could be achieved. However, at higher flow rates, characterized by a lower...

Previous studies reported that polymer retention increases with increased injection rate ( Maerker 1973 ; Dominguez and Willhite 1976; Aubert and Tirrell 1980 ; Zaitoun and Kohler 1987 ; Huh et al 1990 ). However, in the literature, hydrodynamic retention has not been quantified for different flow rates...
