چکیده مقاله:
It is of the great importance to find the mechanisms through which scale inhibitors (SIs) could mitigate mineral precipitation. Accordingly, the current work puts the brine-brine interactions in the absence and presence of a commercial phosphonate-based SI under examination. To achieve this goal, the ۷-day static tests were carried out at ۳۶۳ K and ۱ atmosphere. Moreover, the extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory was utilized to explore the interactions between gypsum particles immersed in the brines of ۳۰۰۰ mg/L and ۶۰۰۰ mg/L of [Ca۲+] while the gypsum-brine surface energy properties play a crucial role. The findings revealed that the SI markedly mitigates the precipitation propensity.
