An Eco-Friendly Quaternary Ammonium Salt as a Corrosion Inhibitor for Carbon Steel in 5 M HCl Solution: Theoretical and Experimental Investigation
Jalab, Rem; Saad, Mohammed A.; Sliem, Mostafa H.; Abdullah, Aboubakr M.; Hussein, Ibnelwaleed A. ( 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 ... -
An Experimental and Kinetic Study of the Sorption of Carbon Dioxide onto Amine-Treated Oil Fly Ash
Saad, Mohammed A.; Al-Marri, Mohammed J.; Yaumi, Ali L.; Hussein, Ibnelwaleed A.; Shawabkeh, Reyad ( Hindawi Publishing Corporation , 2016 , Article)A new CO2 adsorbent is produced from waste oil fly ash (OFA). Ammonium hydroxide solution is used to convert OFA to activated carbon. Then, the product is used for the adsorption of CO2 from a nitrogen/carbon dioxide ... -
DFT-MD dissolution of oilfield pyrite scale using borax
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Ahmed, Musa E.M.; Saad, Mohammed A.; Aparicio, Santiago ( Qatar University Press , 2020 , Poster)Introduction: Oilfield scales including pyrite form in oil and gas pipelines, underground tubing, and surface equipment thus blocking the flow of fluids and hindering production. Hence, the need for the development of ... -
Effect of pH on acidic and basic chelating agents used in the removal of iron sulfide scales: A computational study
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Saad, Mohammed A.; Mahmoud, Mohamed; Ahmed, Musa E.M.; Nimir, Hassan I.... more authors ... less authors ( Elsevier B.V. , 2019 , Article)Iron sulfide scale is a major challenge in the upstream section of the oil and gas industry. It is responsible for precipitate formation in tubulars, and it damages equipment. This leads to a loss in production. Mechanical ... -

Nasser, Mustafa S.; Al-Marri, Mohammed J.; Benamor, Abdelbaki; Onaizi, Sagheer A.; Khraisheh, Majeda; Saad, Mohammed A.... more authors ... less authors ( Springer New York LLC , 2016 , Article)The effects of the surface charge type and density C496, C492 and A130LMW polyacrylamides (PAMs) on the rheological behavior of real industrial papermaking suspensions were quantitatively related to the degree of flocculation ... -
Molecular and electronic structure elucidation of Fe2+/Fe3+ complexed chelators used in iron sulphide scale removal in oil and gas wells
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Sultan, Abdullah; Abdel-Azeim, Safwat; Mahmoud, Mohamed; Saad, Mohammed A.... more authors ... less authors ( Wiley-Liss Inc. , 2019 , Article)Quantum chemical calculations based on DFT are employed to study the electronic structure and binding affinity of chelators used in the removal of iron sulphide scales. Three chelating agents, EDTA, HEDTA, and DTPA, are ... -
Synthesis and performance evaluation of poly (acrylamide-co-malonic acid) as FeS scale inhibitor: experimental and theoretical investigations
Ismail, Nadhem; Alshami, Ali; Jalab, Rem; Saad, Mohammed A.; Hussein, Ibnelwaleed A. ( Institute for Ionics , 2023 , Article)This article reports on poly (acrylamide-co-malonic acid) and poly(AM-co-MAc) copolymers that inhibit the iron sulfide scale. The iron sulfide scale is considered as one of the most challenging oilfield scales to dissolve ... -
Theoretical Studies of a Silica Functionalized Acrylamide for Calcium Scale Inhibition
Onawole, Abdulmujeeb T.; Hussein, Ibnelwaleed A.; Saad, Mohammed A.; Ismail, Nadhem; Alshami, Ali; Nasser, Mustafa S.... more authors ... less authors ( MDPI , 2022 , Article)The calcium carbonate (CaCO3 ) scale is one of the most common oilfield scales and oil and gas production bane. CaCO3 scale can lead to a sudden halt in production or, worst-case scenario, accidents; therefore, CaCO3 scale ...
