Process Plant Simulations Using MATLAB
Abstract: This paper explains the systematic procedure to perform steady state process simulations of process plants using MATLAB. This procedure is illustrated with ethylacetate production process. Sequential modular approach is used to solve the material and enthalpy balance calculations in the flowsheet. Phase equilibrium behaviour plots and sensitivity analysis plots are drawn using MATLAB. Results obtained are compared with the ASPEN PLUS V8.8 simulation results.

Reactive Distillation Design and Control
Abstract: This study deals with the design and control strategies of reactive distillation process. Steady state design including phase equilibrium and chemical equilibrium were studied. Dynamic simulations were conducted by designing control structure. The developed control structure contains level controller, pressure controller, temperature controller. The developed control structure has shown good performance in withstanding the various process disturbances

Distinctive Approaches for Improving the Aqueous Solubility of BCS Class II Drugs
Abstract: The most difficult feature of many novel chemical entities is their solubility behaviour, as 60 percent of new promising products suffer solubility limitations. This is the most common reason for novel medicine compounds failing to reach the market or performing to their full potential. The proportion of the aqueous phase when the solution is in equilibrium with the pure substance in its normal phase is referred to as aqueous solubility. …

Numerical Simulation of Transient Free Convection in a Rectangular Cavity Filled with Porous Material Using Finite Element Formulations
Abstract: In this study, the finite element method is used to quantitatively explore transient free convection in porous cavities in order to understand the flow characteristics and heat conduction processes in the square cavities. In comparison to an uniform temperature gradient, the left wall is swiftly heated and the right wall is allowed to cool to a specific temperature. The horizontal walls are insulated on both sides. Dimensionless representations of the …

Esterification in Reactive Distillation Column Using Software Packages: A Review
Abstract: Abstract: Reactive distillation is the combination of reaction and separation in a same column. This represents an exciting alternative to traditional liquid phase chemical reaction processing. In reactive distillation, separation of products from unconverted reactants allows for better conversion, because produce elimination put out of place equilibrium and forces the reaction towards completion. The energy requirement of the conventional column is very and requires large recycling costs. Reactive Distillation is …

The Effect of Dynamics and Mass Transfer Limitation on the Kinetic Growth Rate of Methane Gas Hydrates
Abstract: Hydrate management aims to prevent impediments to fluid flow in pipes caused by hydrate deposition. To achieve this goal effectively, a comprehensive understanding of the thermodynamics and kinetics of hydrate formation is essential for predicting their equilibrium conditions, quantifying the amount of deposition, and estimating the associated risk. Hydrate growth studies are a relatively new field, and independent laboratory experiments have shown that hydrate growth is controlled by heat transfer, …

Potential of the Biokinetic Integrity of Chromolaena Odorata leaf as Bio-stimulant for Petroleum Hydrocarbon Remediation in Soil
Abstract: The biokenitic parameters of each TPH degradation in the various reactors set-up was determined in terms specific rate of TPH degradation, maximum specific rate of TPH degradation and the equilibrium or dissociation constants as well as the rate of TPH degradation (-kd) or the decay rate of TPH. The value of -kd is within the range of -0.0551 to -0.0151 for room dried and -0.0447 to 0.0118 for sundried whereas …

An Appraisal on Concept of Ama with Special Reference to Xenobiotics
Abstract: Concept of ama is a unique entity in Ayurveda. The term ama denotes several meanings such as unprocessed food, partially digested food, the food which needs further transformation etc. It is the first stage of vranashotha and has main role in vyadhi utpatthi hence vyadhi also carries synonym as amaya. Impaired agni is the prime cause for ama utpatthi and it has the capacity to vitiate dosha, thereby disturbing the …

Hexavalent Chromium Resistance Test of Saccharomyces Cerevisiae and Modeling of its Bioaccumulation Process
Abstract: Now a day, the release of high chromium containing tannery waste water from tanning industries to the environment is the life threatening action of human activities and bioaccumulation becomes a better alternative in treating heavy metals(such as Cr(VI) )due to its cost effective, relatively high heavy metal removal capacity and recovery property. Cell suspensions of S.cerevisiae at its exponential growth phase were added to 250 ml plastic flasks of containing …

Comprehensive study of Entanglement Entropy in Quantum Field Theory: Analysis of Conformal Field Theory to Massive Field Extensions and Holographic Entanglement
Abstract: This paper provides an in-depth analysis of entanglement entropy (EE) in quantum field theory (QFT), with a particular focus on its computation using the replica trick and its applications to both conformal and non-conformal systems. Beginning with an introduction to the basics of QFT, the study explains how entanglement entropy quantifies the quantum correlations between subsystems in a pure state, represented by the von Neumann entropy of the reduced density …
