Hybrid coagulation-NF membrane processes for brackish water treatment: Effect of pH and salt/calcium concentration
( Elsevier B.V. , 2016 , Article)In order to reduce membrane fouling propensity, membrane technologies in water treatment and desalination processes have been coupled with coagulation process. However, the fouling issues still persisted. It is believed ... -
Iron Sulfide Scale Inhibition in Carbonate Reservoirs
( American Chemical Society , 2022 , Article)Hydrocarbon production operations include water injection, varying stimulation approaches, and enhanced oil recovery techniques. These treatments often affect reservoir formation, production, and injection facilities. Such ... -
Phosphonated Lower-Molecular-Weight Polyethyleneimines as Oilfield Scale Inhibitors: An Experimental and Theoretical Study
( American Chemical Society , 2022 , Article)For many years, amino methylenephosphonate (-CH2-N-PO3H2)-based scale inhibitors (SIs) have been deployed for preventing various scales in the oil and gas industry, particularly for squeeze treatment applications. However, ... -
Synthesis and evaluation of a novel polyacrylamide functionalized nano-silica as a calcium carbonate inhibitor in upstream applications
( Elsevier B.V. , 2022 , Article)Calcium carbonate scale forms in production and injection wells, precipitating upon pressure and temperature changes, incompatible water mixing, and dehydration. Production shutdown is one of the most dramatic consequences ...
