Review on the Use of Ionic Liquids (ILs) as Alternative Fluids for CO2 Capture and Natural Gas Sweetening
( American Chemical Society , 2010 , Article)The capture of CO2 from flue gases derived from fossil-fueled power plants and the absorption of CO2/H2S for natural gas sweetening purposes are two relevant industrial problems closely related to very important environmental, ... -
Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
( AIChE , 2015 , Conference Paper)Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ... -
Rheological, Thermodynamic, and Gas Solubility Properties of Phenylacetic Acid-Based Deep Eutectic Solvents
( Wiley-VCH Verlag , 2017 , Article)Choline chloride + phenylacetic acid-based deep eutectic solvents are studied. Their most relevant experimental physicochemical properties at different mixing ratios together with the CO2 solubility data obtained in wide ... -
Rheology of organoclay assisted extrusion of HDPE using Particle Image Velocimetry
( Institution of Chemical Engineers , 2015 , Article)Wall slip is often seen as a source of flow enhancement and can play a significant role during certain melt instabilities in polymer processing. In the present investigation, the effect of organoclay on the wall slip of ... -
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 ... -
Rheology of upstream complex fluids
( Elsevier , 2023 , Book chapter)Rheology is an important characterizing technique as it affects all types of fluids. While oil and gas recovery is an operation that depends mainly on the interaction between different fluids, it is therefore important to ... -
Roadmap toward energy-positive upfront nitrogen removal process in baseload LNG plant
( John Wiley and Sons Ltd , 2022 , Article)The use of liquefied natural gas (LNG) has grown over the last decade owing to an increase in the global energy demand. This work presents a pioneering approach for rigorous simulation of an actual cold section of an LNG ... -
Role of catalyst type in the selective separation of olefinic and paraffinic hydrocarbons using xerogel-based adsorbents
( Elsevier , 2008 , Article)Resorcinol-Formaldehyde (RF)-based activated carbon xerogels are typically synthesized using a homogeneous, sodium-based, catalyst solution. In this work, the synthesis of RF-based carbon xerogels using other, non-typical, ... -
