“…Using the osmotic coefficient, activity coefficient and the solubility products of the equilibrium solid phases allowed us to identify the coexisting solid phases and their compositions at equilibrium. On Pitzer ion-interaction model and its extended HW model, a numbers of papers were successfully utilized to predict the solubility behaviors of natural water systems, salt-water systems, and even geological fluids (Felmy & Weare, 1986;Kim & Frederich, 1988a, 1988bFang et al, 1993;Song, 1998;Song & Yao, 2001Yang, 1988Yang, , 1989Yang, , 1992Yang, , 2005.…”

He obtained his B.Sc in physical chemistry from Bar-Ilan University in 1989 and received his PhD from the Weizmann Institute of Science with Prof. Gary Hodes on nanomaterials synthesis (1999). He then went to the Max Planck institute of colloids and interfaces for 3 years, as postdoctoral fellow to work with Prof. M. Antonietti and Prof. H Cölfen on biomimetic chemistry and chiral polymers. In 2003 joined the staff of the chemistry department at Bar-Ilan University, where he is currently a Professor at the institute of nanotechnology at Bar-Ilan University leading the nano chirality laboratory. Prof. Mastai's earlier interests included nanomaterials synthesis and characterization. His current research is focused on the synthesis and analysis of chiral nanosurfaces, chiral self-assembled monolayers and polymeric chiral nanoparticles. Mastai has published more than 100 scientific articles and book chapters on various aspects of nanomaterials and chirality at the nanoscale.XIV Contents I wish to thank all the authors for their contributions for this book and it is my pleasure to acknowledge the assistance of Ms Vana Persen for her assistance during the write-up of this book and is preparation in final format.Finally I would like to acknowledge my family who has supported me through all the years of doing science. To my wife Dina von Schwarze and to our children Michael, Reut and Noa for their patience and support.

“…The thermodynamics, kinetics, and machenisms of scale formation in brine and organic co-solvent solutions have been extensively investigated both experimentally and theoretically [3][4][5][6][7][8][9][10] . However, despite the importance of MEG as an effective gas hydrate inhibitor, there is little research focused on the solubility of mineral scles in salt and MEG solutions.…”

Monoethylene Glycol (MEG), HOCH 2 CH 2 OH, is an important raw material with numerous industry applications, which include polyester synthesis, automobile antifreeze, coolant, and aircraft anti-icer. In oil and gas industry, MEG is commonly used as a gas hydrate inhibitor, which can prevent the formation of gas hydrate during the production of oil and gas in oil wells. However, MEG has the adverse effects on the solubility of minerals. The lowering solubility of minerals will result in the precipitation of mineral scales, which is another serious problem in the production of oil and gas and also causes scaling problems during glycol regeneration.Despite the importance of scale problems with MEG in oil production, there are few investigations on the solubility of mineral salt in the co-solvent of MEG and brine solutions due to the complexities of this mixed-solvent system. In this research, experiments have been conducted on the carbonate equilibrium and the solubility of calcite at 2 o C-70°C, 0-6.5 m ionic strengths, and 0-100% MEG. MEG activity coefficients with respect to dissolved CO 2 , bicarbonate, carbonate, and calcium are determined as a function of temperature, ionic strength, and mole fraction MEG in mixed solvent.A self-consistent activity model is proposed based on the data obtained from this study. Pitzer theory was used to calculate the effect of salt and a Born type equation was applied to analyze the effects of MEG. This model can predict mineral scales solubility in the presence of MEG and brine solutions, provide a better understand of effects of MEG on solubility of scales, and gain an insight into the scale inhibitor studies.
