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 ...
Benchmarking the Self-Assembly of Surfactin Biosurfactant at the Liquid–Air Interface to those of Synthetic Surfactants
(
Springer-Verlag
, 2016 , Article)
The adsorption of surfactin, a lipopeptide biosurfactant, at the liquid–air interface has been investigated in this work. The maximum adsorption density and the nature and the extent of lateral interaction between the ...
Effect of charge type and density of polyacrylamide on the electrokinetics behavior of flocculated bentonite suspensions
(
AIChE
, 2016 , Conference Paper)
The study of electrokinetics behavior of clay suspensions is of fundamental importance in many industrial applications. This paper addresses the electrokinetics behavior of polyacrylamide (PAM)- bentonite suspensions. The ...
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 ...
Investigation of thin-film composite hollow fiber forward osmosis membrane for osmotic concentration: A pilot-scale study
(
Springer
, 2022 , Article)
The current study applied the forward osmosis (FO) based osmotic concentration (OC) process at the pilot-scale for concentrating synthetic feed solution (FS). The process water (PW) salinity represents effluents from the ...
Settling behavior of fine cuttings in fiber-containing polyanionic fluids for drilling and hole cleaning application
(
Elsevier B.V.
, 2021 , Article)
For efficient drilling operations, cuttings transport within the oil and gas wellbore is fundamental. Inadequate hole cleaning results in many problems including reduced rate of penetration, increased torque, bit wearing, ...
