Thermodynamics and kinetics of CH4/CO2 binary mixture separation by metal-organic frameworks from isotope exchange and adsorption break-through
(
Elsevier B.V.
, 2018 , Article)
We combine the isotope exchange technique (IET) with the conventional Sieverts method, microcalorimetry, breakthrough experiments and multi-scale modelling to comprehensively and quantitatively investigate the thermodynamics ...
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 ...
Impact of Surfactant on the Retention of CO2 and Methane in Carbonate Reservoirs
(
American Chemical Society
, 2018 , Article)
Enhanced gas recovery methods such as foamed CO2 are recommended for depleted gas reservoirs. Viscoelastic surfactant (VES) is a form of a surfactant used for forming CO2 foam. In this study, the impact of VES on CH4 and ...
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 ...
Development of efficient formulation for the removal of iron sulphide scale in sour production wells
(
Wiley-Liss Inc.
, 2018 , Article)
Iron sulphide scale, which exists in different forms, is common in sour oil and gas production wells. Iron sulphide hard scales are difficult to remove with acids, requiring mechanical intervention or the replacement of ...
Molecular Modeling Study toward Development of H2S-Free Removal of Iron Sulfide Scale from Oil and Gas Wells
(
American Chemical Society
, 2018 , Article)
A common problem that faces the oil and gas industry is the formation of iron sulfide scale in various stages of production. Recently an effective chemical formulation was proposed to remove all types of iron sulfide scales ...
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 ...
Bioremediation and nutrient removal from wastewater by Chlorella vulgaris
(
Elsevier B.V.
, 2018 , Article)
The capability of the microalgae Chlorella vulgaris (Cv) for biomass production and nutrients removal under different wastewater quality has been studied. Cv was cultivated in a standard medium (Marine labs American society ...
Hydrothermally grown ZnO electrodes for improved organic photovoltaic devices
(
Elsevier B.V.
, 2018 , Article)
Here we report a simple, solution based processing route for the formation of large surface area electrodes resulting in improved organic photovoltaic devices when compared with conventional planar electrodes. The ...
Gas solubility and rheological behavior study of betaine and alanine based natural deep eutectic solvents (NADES)
(
Elsevier B.V.
, 2018 , Article)
Natural deep eutectic solvent (NADES) produced herein this work by mixing betaine and alanine with lactic acid and malic acid with 1:1 M mixing ratios. Thermophysical properties including water content, thermal stability, ...
