Computation Of Fifteen Thermodynamic Properties Along Arbitrary Paths From Fundamental Equations Of State Correlations, Prashanth Krishnamoorthy
Computation Of Fifteen Thermodynamic Properties Along Arbitrary Paths From Fundamental Equations Of State Correlations, Prashanth Krishnamoorthy

In this work, a set of fifteen thermodynamic properties for thirty pure compounds has been estimated using fundamental equations of state (FEOS). A computer program was written which allows to input any two of four fundamental thermodynamic properties entropy, pressure, temperature and density to fix a state point and then use the FEOS to generate any other property at that given state. The program further applies the FEOS to trace thermodynamic processes like isochoric, isobaric, isenthalpic, isothermal and isentropic state changes to find the final state of the compound. The program subsequently displays the initial, final and intermediate state points …

Oxygen is used in a variety of chemical processes and for medical purposes throughout the world. Pressure swing adsorption (PSA) has become a viable alternative to cryogenic distillation for the separation of oxygen from air with the development of advanced adsorbents like zeolites. PSA processes are inherently complex because it is a dynamic process. Efficient operation of a PSA process is necessary in order to utilize the capacity of the adsorbent as much as possible and reduce the power requirements of the process.In this thesis, a novel zeolite adsorbent was utilized in a PSA process for oxygen generation with the …

Accurate values for thermodynamic properties throughout the fluid phase are a requirement for the design of separation processes. To date, very few pure substances have been completely characterized because of time and monetary constraints. Low cost computing power now permits complete determination of the thermodynamic properties of pure substances via molecular simulation. Molecular simulation is computational statistical mechanics. Benzene is an important industrial chemical and pharmaceutical precursor. It is the prototypical, symmetric, hexagonal molecule and is an ideal candidate for molecular simulation. The molecular models of three researchers in the field are submitted for Monte Carlo simulation in the virtual …
