Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments
(
Elsevier Ltd
, 2020 , Article)
Large amounts of agricultural solid wastes (ASWs) and animal dung are produced annually causing serious environmental problem that requires proper treatment. The present study proposes a strategy for optimizing the anaerobic ...
Prediction of biogas production from chemically treated co-digested agricultural waste using artificial neural network
(
Elsevier Ltd
, 2020 , Article)
The present study evaluates the effect of co-digestion of agricultural solid wastes (ASWs), cow manure (CM), and the application of chemical pre-treatment with NaHCO3 on the performance of anaerobic digestion (AD) process. ...
Solar oxidation of toluene over Co doped nano-catalyst
(
Elsevier Ltd
, 2020 , Article)
Cobalt (Co) co-doped TiO2 photo-catalysis were synthesized, characterized and tested toward solar photocatalytic oxidation of toluene (TOL). A multi-technique approach was used to characterize and relate the photo-catalytic ...

Ab Initio molecular dynamics of the dissolution of oilfield pyrite scale using borax
(
Elsevier B.V.
, 2020 , Article)
Iron sulfide scales, particularly pyrite, form in oil and gas underground tubing and surface equipment thus blocking the flow of fluids and halting production. Therefore, the development of physicochemical processes for ...
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 ...
Concurrent adsorption of cationic and anionic dyes from environmental water on amine functionalized carbon
(
IWA Publishing
, 2020 , Article)
Amine functionalized carbon (AFC) was synthesized from raw oil fly ash and later utilized it for simultaneous removal of methyl orange (MO) and rhodamine 6G (Rh6G) pollutant dyes from aqueous medium. AFC was analyzed through ...
Characterization of polysulfone/diisopropylamine 1-alkyl-3-methylimidazolium ionic liquid membranes: high pressure gas separation applications
(
Blackwell Publishing Ltd
, 2020 , Article)
Membrane separation is gaining great attention in many applications, especially in gas separation. Polysulfone (PSF) is the most widely studied polymeric membrane material for CO2 in its pure or modified state. Ionic liquids ...
Key applications and potential limitations of ionic liquid membranes in the gas separation process of CO2, CH4, N2, H2 or mixtures of these gases from various gas streams
(
MDPI AG
, 2020 , Article Review)
Heightened levels of carbon dioxide (CO2) and other greenhouse gases (GHGs) have prompted research into techniques for their capture and separation, including membrane separation, chemical looping, and cryogenic distillation. ...
