Extracted quartz as efficient natural demulsifier for crude oil-water emulsions: Effect of monovalent/divalent salts, pH and modeling study

Smooth running of upstream and downstream operations is very key for the successful hydrocarbon production and delivery to the end users. Investigated in this study is the application of quartz particles as naturally occurring demulsifiers for demulsification activity in the petroleum industry. Effect of monovalent (NaCl and KCl) and divalent (MgSO4.7H2O, CaCO3, CaCl2 and MgCl2.6H2O) salts on the effectiveness of quartz (3 wt%) to displace the...
