Pyrite-scale removal using glutamic diacetic acid: A theoretical and experimental investigation
(
Society of Petroleum Engineers (SPE)
, 2021 , Article)
Iron sulfide scale causes major losses in both upstream and downstream sectors of the hydrocarbon industry. Pyrite is one of the most-difficult forms of iron sulfide scale from a removal point of view. Inorganic acids such ...
Nickel/Cobalt nanoparticles for electrochemical production of hydrogen
(
Elsevier Ltd
, 2021 , Article)
The electrolytic production of hydrogen (POH) from alkaline water electrolysis is at the forefront of technology for alternative energy sources of the future. The present work evaluates the improvement of electro-catalytic ...
Environmental impacts of solar photovoltaic systems: A critical review of recent progress and future outlook
(
Elsevier B.V.
, 2021 , Article)
Photovoltaic (PV) systems are regarded as clean and sustainable sources of energy. Although the operation of PV systems exhibits minimal pollution during their lifetime, the probable environmental impacts of such systems ...
Physicochemical, structural and combustion analyses to estimate the solid fuel efficacy of hydrochar developed by co-hydrothermal carbonization of food and municipal wastes
(
Springer Nature
, 2022 , Article)
The application of a char derived from fruit peel waste and other municipal wastes as solid fuel depends on its physico-chemical properties. In this work, fruit peel waste (FW) along their mixture with facial tissue waste ...
Density-Functional Theory Investigation of Barite Scale Inhibition Using Phosphonate and Carboxyl-Based Inhibitors
(
American Chemical Society
, 2020 , Article)
Scale deposition is a critical issue in oil and gas exploration and production processes, causing significant blocking in tubing and consequently flow assurance and economic losses. Most studies addressing the scale formation ...
Molecular dynamics of CH4/CO2 on calcite for enhancing gas recovery
(
John Wiley and Sons Inc
, 2022 , Article)
The effect of temperature and pressure on the adsorption of CO2 and CH4 gases on calcite (104) has been studied by means of classical molecular dynamics. The results show that carbon dioxide greatly improves methane ...
Lithium loaded coal fly ash as sustainable and effective catalyst for the synthesis of glycerol carbonate from glycerol
(
Elsevier Ltd
, 2021 , Article)
Coal fly ash (CFA) has been employed as a catalytic support for lithium ions by impregnation. The basicity, basic strength, and stability of the resultant catalyst were further tuned by varying active species concentration ...
Influence of choline chloride based natural deep eutectic solvent on the separation and rheological behavior of stable bentonite suspension
(
Elsevier B.V.
, 2021 , Article)
Colloids in wastewater are considered a serious problem due to their stability and separation difficulty. Coagulation/ flocculation processes are the most common for the separation of colloids because of their high-performance ...
