Prediction of sand kinematic pressure and fluid-particle Interaction Coefficient as means of preventing sand-induced corrosion in crude oil pipelines
Ain Shams Engineering Journal, 2019Co-Authors: Samuel Eshorame Sanni, Sam Sunday Adefila, Ambrose Nwora AnozieAbstract:Sand-induced corrosion and scaling of petroleum pipes is a serious situation that barely knows any solution by conventional or new methods of corrosion control. This is because, the mechanism behind sand corrosion and scaling of petroleum pipes is yet to be unravelled. Rather than avoid the situation, the integration of sand filters in petroleum lines also contribute to the problem. In this work, a three phase model was used to simulate upstream flow conditions where sand is produced alongside water and crude oil. The effects of fluid-particle Interaction Coefficient/forces and sand kinematic pressure, in relation to conditions that favour sand deposition, corrosion and scaling of petroleum pipes were determined. Based on the results, on a 2–3 h basis, periodic checks need be conducted at the 12–18 m points where sand kinematic pressures and Interaction Coefficients of the components require flow adjustments in order to avoid situations leading to pipeline wea

The Journal of Chemical Thermodynamics, 2020Co-Authors: Harsh Kumar, Vaneet Kumar, Seema Sharma, Arjuna Katal, Asma A AlothmanAbstract:Abstract The physicochemical properties of amino acids like L-Leucine and L-Serine in aqueous solution of ammonium dihydrogen Phosphate (ADP) at different temperature analysed by volumetric and acoustic methods. By using density data, apparent molar volume Vϕ ,partial molar volume V ϕ 0 and standard partial molar volume of transfer Δ V ϕ 0 have been evaluated. From speed of sound data, apparent molar isentropic compression K ϕ , s apparent partial molar isentropic compression K ϕ , s 0 and partial molar isentropic compression of transfer Δ K ϕ , s o have been calculated. The pair and triplet Interaction Coefficient have also been calculated. The results have been interpreted in terms of solute – solute and solvent-solvent Interactions.

The Journal of Chemical Thermodynamics, 2018Co-Authors: Nabaparna Chakraborty, Harsh Kumar, Kirandeep Kaur, K C JuglanAbstract:Abstract The Interaction of EG, DEG and TEG with biologically active D-Panthenol, as the function of temperature has been investigated by the combination of acoustic and volumetric methods. Speeds of sound and densities of EG, DEG and TEG in (0.05, 0.10 and 0.15) mol·kg−1 in aqueous solutions of D-Panthenol have been measured at T = (293.15, 298.15, 303.15 and 308.15) K. From the density data, the apparent molar volume ( V ϕ 0 ) and standard partial molar volume of transfer Δ V ϕ 0 for EG, DEG and TEG in aqueous D-Panthenol solutions have been determined. From the speed of sound data, the partial molar isentropic compression K ϕ , s and the partial molar isentropic compression of transfer Δ K ϕ , s 0 , have been determined.

modeling grain boundary segregation by prediction of all the necessary parameters
Acta Materialia, 2019Co-Authors: Pavel Lejček, Siegfried HofmannAbstract:Abstract A thermodynamic model of equilibrium grain boundary segregation in real binary systems is proposed which is based on the prediction of all the necessary parameters. These parameters are (i) the standard enthalpy and (ii) the standard entropy of grain boundary segregation, both related to ideal behavior, as well as (iii) the Fowler binary Interaction Coefficient describing the real contribution. Application of the model is shown in detail for the example of iron-based binary systems and predictions are compared to data published in the literature.
