Effect of binary mixture of waste plastics on the thermal behavior of pyrolysis process
( John Wiley and Sons Inc , 2015 , Article)Waste plastic is non-biodegradable material that does not decompose naturally for a long time. The pyrolysis process is a reliable method to decompose plastic wastes, which involves breaking of the heavy carbon chains and ... -
CO<inf>2</inf> solubility in aqueous potassium lysinate solutions at absorber conditions
( Academic Press , 2017 , Article)In this work, CO2 solubility in aqueous potassium lysinate solutions has been measured for the concentrations of (1.25–3.28) mol·kg−1 and at temperatures of (313–343) K. The vapour-liquid equilibrium data were correlated ... -
Evaluating greywater and A/C condensate daily volume and water quality in urban settings
( American Society of Agricultural and Biological Engineers , 2011 , Conference Paper)Due to increasing water demand as a result of population growth and improvement in living standards, many countries with arid climate are already facing water shortages that are being met by expensive desalination projects. ... -
A/C condensate for water reuse: An approach towards environmental sustainability in Doha
( American Society of Agricultural and Biological Engineers , 2012 , Conference Paper)A/C Condensate is a relatively untapped alternative source of water that might be readily available especially in hot arid climates. The objective of this study is to establish the feasibility of the A/C condensate as the ... -
Numerical simulation of thermal buoyant wall jets
(2013 , Conference Paper)The main focus of this study is on the near field flow and mixing characteristics of the thermal wall jets. A numerical study of the buoyant wall jets discharged from submerged outfalls from cooling systems of power ... -
An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference Paper)In this study, a new finite volume method is developed for shallow water equations on a rotating frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or numerical damping for ... -
Electronic waste considerations in the Middle East and North African (MENA) region: A review
( Elsevier , 2023 , Article Review)Waste Electrical and Electronic Equipment or e-waste is a waste stream that has multiplied profoundly in recent years. Currently, many researchers focused on the study of e-waste. The Middle East & North Africa (MENA) is ... -
Electrochemical reduction of carbon dioxide to hydrocarbons
( Elsevier , 2022 , Book chapter)Global accumulation of CO2 in the atmosphere has become a significant environmental challenge in the past twodecades. Global warming and climate change resulting from increasing concentrations of CO2 are of utmost concern ... -
A Mechanistic Model for Wellbore Cleanout in Horizontal and Inclined Wells
( Society of Petroleum Engineers (SPE) , 2021 , Conference Paper)The accumulation of rock cuttings, proppant, and other solid debris in the wellbore caused by inadequate cleanout remarkably impedes field operations. The cuttings removal process becomes a more challenging task as the ... -
Rapid Curing Environmentally Degradable Polymeric Pill for Loss Circulation Treatment
( Society of Petroleum Engineers (SPE) , 2022 , Conference Paper)Loss circulation is frequent while drilling in naturally fractured or depleted reservoirs, which is usually associated with high non-productive time (NPT). Moreover, naturally pre-existing fractures may propagate when fluid ... -
Effects of Pipe Rotation on the Performance of Fibrous Fluids in Horizontal Well Cleanout
( Society of Petroleum Engineers (SPE) , 2022 , Conference Paper)The deposition of rock cuttings is a problem commonly faced during drilling, completion, and intervention operations. Using polymer-based fluids is a common technique to improve horizontal downhole cleaning. However, these ... -
Investigation of Matrix Damage and Remediation Methods of Preformed Particle Gel Conformance Control Treatments in Carbonate Reservoirs
( Society of Petroleum Engineers (SPE) , 2022 , Conference Paper)Preformed Particle Gels (PPGs) have been widely applied to control excessive water production in mature oil fields with fractures or fracture-like features, especially in sandstones, but with limited attention to carbonates. ... -
Machine Learning for Capillary Pressure Estimation
( Society of Petroleum Engineers (SPE) , 2022 , Article)Capillary pressure plays an essential role in controlling multiphase flow in porous media and is often difficult to be estimated at subsurface conditions. The Leverett capillary pressure function J provides a convenient ... -
Chitosan/Polyacrylamide Green Gels for Water Control in High-Temperature Reservoirs
( American Chemical Society , 2022 , Article)The rheology of a gel system composed of polyacrylamide (PAM) and chitosan is studied under typical reservoir conditions. The impacts of the degree of chitosan deacetylation, temperature, and salinity on the gelation ... -
Effect of Fluid Rheology on the Performance of Fibrous Fluid in Horizontal Well Cleanout
( Society of Petroleum Engineers (SPE) , 2022 , Conference Paper)The deposition of solids in the wellbore is a widely known problem encountered during drilling, completion, and intervention operations. Innovative cleanout fluids alleviate problems associated with inefficient hole cleaning. ... -
An Eco-Friendly Quaternary Ammonium Salt as a Corrosion Inhibitor for Carbon Steel in 5 M HCl Solution: Theoretical and Experimental Investigation
( MDPI , 2022 , Article)The corrosion of industrial material is a costly problem associated with global economic losses reaching trillions of US dollars in the repair of failures. Injecting corrosion inhibitors is the most practically promising ... -
