Determination Of VLE Data For System Containing CPME

Abstract

Conventional solvents used in industries create so many problems like environmental, health and safety. Green solvents provide an attractive alternate to the conventional solvents. Cyclopentyl methyl ether is one of the green solvents. Temperature dependent physical properties like vapor pressure, heat of vaporization, heat capacity is not available in the literature for CPME. These properties play an important role in designing the processes involving CPME. One of the routes to produce CPME is the cyclopentanol. In this present work purpose for CPME, Cyclopentanol and Dimethyl sulphate and their binary mixtures is proposed. In first phase pure component properties are determined. Vapor pressure is an important property for many reasons. It provides the idea about handling and storage of the chemicals as well as it can be used for predicting other thermo-physical properties. The report lists the experimentally measured vapor pressure data of CPME. The experiments were carried out using Ebuilliometer.

The experimental vapor pressure data was fitted to Antoine equation, Prediction of vapor pressure of CPME, Cyclopentanol were also done using CEOS. The development of an accurate theory for associating fluids has been a challenin field of research in Thermodynamics. Phase Equilibrium study is the key job to be carried out in any equipment design. Here Phase Equilibrium study has been carried out using Activity co-efficient Models. Experimental phase equilibrium experiments was carried out for binary system using differential Ebulliometer. Vapor pressure of pure component and mixtures were obtained experimentally. Vapor-Liquid Equilibrium(VLE) data are essential to design a seperation process of liquid mixtures of distillation. With this purpose and due to the absence of literature data, Isobaric VLE data for the binary mixture of Cyclopentyl methyl ether and cyclopentanol have been enerated. The experimental data were corelated by GEbased models(Margules 2-suffix, Margules 3-suffix, Van-Laar, Wilson, NRTL).

In the present work Activity coefficient model parameters were regressed using experimental P-T-x data. Experimental P-T-x data were modeled to find vapor phase composition using GE based models with regressed parameters(Binary interaction parameters).
