Conceptual Design and Model Approach of an Amine Based on CO 2 Capture

By Victor Chukwuemeka Ukpaka, Abraham Peter Ukpaka, and C. P. Ukpaka

Abstract: The research work on the conceptual design and model approach of an amine base CO 2 capture, Fluegases are conveyed through the absorber, where carbon dioxide is chemically absorbed using anaqueous monoethanolamine (MEA) solution that is delivered to the column at its top. Due to theincreased contact area between the phases, both phases travel through…

Integrated Process Design and Simulation of Amine-Based CO₂ Capture: A Path to Emission Control

By Abraham Peter Ukpaka, Victor Chukwuemeka Ukpaka, Joy Chukwuemeka Peter Ukpaka, and C. P. Ukpaka

Abstract: The flow sheet must represent the complete process in detail taking care of all process equipment. ASPEN HYSYS simulation software was used to simulate the process, the models of the process was simulated using MATLAB. The concentration of the atmospheric CO 2 was found to having been increasing steadily and has risen up to 35%…

Investigation of Thermo-Acoustic Properties of Ethanol-Cyclohexane Binary Mixture

By Dr. Ashish Wakulkar, Priyanka bhukya, Lanjewar M. R, and Shah S. A.

Abstract: The density, viscosity, and speed of sound for ethanol-cyclohexane binary mixtures were determined across mole fractions ranging from 0.1 to 0.9 using an Anton Paar DSA 5000 M within the temperature span of 288.15–318.15 K. From these experimental measurements, several thermodynamic and acoustic properties, such as isentropic compressibility, relative association, free volume, relaxation time, Gibbs…

Non-Equilibrium Entropy Pathways in Complex Fluids: A New Framework for Thermodynamic Irreversibility

By Pankaj Kumar

Abstract: When a system is driven, sheared, stretched, heated, or pressurized under varying thermodynamic gradients and kept away from equilibrium, ultra-microscopic rearrangements begin to occur, indicating continuous energy dissipation. Along these energy pathways, the microstructures of complex fluids undergo multiple stages of reforming and rearrangement. In complex fluids composed of identical compounds (chemically identical species), these…

Thermo-Acoustic Investigation of Molecular Interactions in Aqueous Solutions of L-Histidine at Different Temperatures

By Priyanka bhukya, Dr. Ashish Wakulkar, and Prof. Shaukat Shah

Abstract: The present study investigates the acoustic and thermodynamic behavior of aqueous solutions of L-Histidine across a concentration range of 0.01 m to 0.1 m and temperatures varying from 293.15 K to 318.15 K in 5 K intervals. Ultrasonic velocity (μ), density (ρ), and viscosity (η) measurements wereconducted with high precision to understand the solution behavior…

Thermoacoustic Properties of Ethanol-n-Hexane and 1-Propanol-n-Hexane Binary Mixtures: A Comparative Study at 298.15 K

By Dr. Ashish Wakulkar, Shah S. A., Priyanka bhukya, and Ban P. W.

Abstract: Using an Anton Paar DSA 5000 M instrument, measurements of density, sound velocity, and viscosity were carried out for ethanol–n-hexane and 1-propanol–n-hexane binary mixtures across mole fractions ranging from 0.1 to 0.9 at a constant temperature of 298.15 K. These binary mixtures were specifically selected to investigate the behavior of polar–nonpolar molecular interactions and how…
