Polymeric Surfactants and Emerging Alternatives used in the Demulsification of Produced Water: A Review
(
Taylor and Francis Inc.
, 2018 , Article Review)
Stable emulsions are frequently encountered in oil production and cause a series of environmental and operational issues. Chemical demulsification is widely used for the separation of oil from water or removal of water ...
Thermal degradation of aqueous amine/amino acid solutions in the presence and absence of CO 2
(
Institute of Physics Publishing
, 2018 , Conference Paper)
The stability to thermal degradation of aqueous solutions of methyldiethanolamine (MDEA) and their mixtures with glycine (Gly), in the absence and the presence of CO 2 , was investigated by Gas chromatography-flame ionization ...
Aqueous dispersions of carbon black and its hybrid with carbon nanofibers
(
Royal Society of Chemistry
, 2018 , Article)
The aqueous dispersions of a special type of carbon black (CB) in 1 M lithium bis(trifluoromethanesulfonimide) electrolyte is mainly controlled by the affinity of the aqueous electrolyte towards the CB particles rather ...
Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
(
American Chemical Society
, 2019 , Article)
Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength ...
Carbamate Formation and Amine Protonation Constants in 2-Amino-1-Butanol–CO2–H2O System and Their Temperature Dependences
(
Springer New York LLC
, 2018 , Article)
The apparent protonation constant of an amino butanol (AB) and its carbamate formation constant in the CO2–H2O–AB system were determined at T = 298.15–328.15 K, and at various ionic strengths up to 0.2 mol·L−1 by potentiometric ...
Reaction Kinetics of Carbon Dioxide with 2-Amino-1-butanol in Aqueous Solutions Using a Stopped-Flow Technique
(
American Chemical Society
, 2018 , Article)
Carbon capture and management plays an important role in the development of new technologies to mitigate anthropogenic global warming. In this work, for the first time, the kinetics of CO2 with aminobutanol (AB) using a ...
Influence of polyelectrolyte architecture on the electrokinetics and dewaterability of industrial membrane bioreactor activated sludge
(
Academic Press
, 2019 , Article)
Improvement of sludge dewaterability is greatly hindered by the presence of large amounts of interstitial water molecules trapped in the sludge as a result of strong hydrophilic characteristics. This study has investigated ...
Influence of modified clay on the structure and performance of polysulfocomposite membrane
(
Desalination Publications
, 2018 , Article)
Highly porous modified clay material with large surface area known as ?Filtralite? was used as a filler for the preparation of polysulfone (PSf) composite membranes. Filtralite concentration in the membrane composition was ...
A comprehensive rheological study for a flowing polymer-based drilling fluid used for wellbore strengthening
(
Society of Petroleum Engineers (SPE)
, 2020 , Conference Paper)
Loss circulation encountered in highly fractured formations, depleted reservoir, or HP/HT intervals is the root cause of many problems plaguing the oil and gas sector for many years. High pore pressure narrows the window ...
Rheology of Triamine Functionalized Silica Reinforced Polymeric Gels Developed for Conformance Control Applications
(
American Chemical Society
, 2020 , Article)
Recently, cross-linked polymers such as polyacrylamide (PAM)/polyethylenimine (PEI) have been used in conformance control applications to replace conventional lost circulation materials (LCMs). The objective of this work ...
