An Investigation of the Swelling Kinetics of Bentonite Systems Using Particle Size Analysis
( Taylor and Francis Inc. , 2019 , Article)Particles size distribution (PSD) is introduced as a tool for analysis of bentonite aggregation and swelling kinetics. Raw Ca-bentonite was purified using a combined wet sieving and sedimentation processes, followed by ... -
Effect of pH on acidic and basic chelating agents used in the removal of iron sulfide scales: A computational study
( 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 ... -
Molecular and electronic structure elucidation of Fe2+/Fe3+ complexed chelators used in iron sulphide scale removal in oil and gas wells
( 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 ... -
Upgrading Calcium Bentonite to Sodium Bentonite Using Seawater and Soda Ash
( American Chemical Society , 2019 , Article)In this paper, a new method is introduced to produce sodium bentonite by treating calcium bentonite using seawater to eliminate the use of freshwater and reduces the amount of soda ash required for the treatment, which ...
