Use the Peng-Robinson equation (kij = 0) to determine the phase envelope of ethane n-heptane at compositions of xC7 = [0, 0.1, 0.2, 0.3, 0.5, 0.7, 0.9, 1.0]. Plot P versus T for each composition by performing bubble-pressure calculations to their terminal point and dew-temperature calculations until the temperature begins to decrease significantly and the pressure … Read more
Consider a mixture of nitrogen(1) + n-butane(2) for each of the options: (i) 395 K and 2 MPa; (ii) 460 K and 3.4 MPa; (iii) 360 K and 1 MPa. (a) Calculate the fugacity coefficients for each of the components in the mixture using the virial coefficient correlation. Make a table for your results at … Read more
One of the easiest ways to begin to explore fugacities in nonideal solutions is to model solubilities of crystalline solids dissolved in high pressure gases. In this case, the crystalline solids remain as a pure phase in equilibrium with a vapor mixture, and the fugacity of the “solid” component must be the same in the … Read more
A mixture of methane and ethylene exists as a single gas phase in a spherical tank (10 m3) on the grounds of a refinery. The mixture is at 298 K and 1 MPa. It is a spring day, and the atmospheric temperature is also 298 K. The mole fraction of ethylene is 20 mol%. Your … Read more

Benzaldehyde is known in the flavor industry as bitter almond oil. It has a cherry or almond essence. It may be possible to recover it using CO2 for a portion of the processing. Explore the phase behavior of the CO2(1) + benzaldehyde(2) system, using the Peng-Robinson equation to categorize the system among the types discussed in … Read more
A reaction occurs with all components present in liquid and gas phases. Compositions in both phases are measured and the activities are calculated. The equilibrium constant value calculated using vapor phase activities is different from the equilibrium constant calculated using liquid phase activities. Is something wrong? Q462 Describe the behavior of the … Read more
One suggestion for sequestering CO2 is to synthesize carbonate polymers. Polycarbonate is well known for its strength and transparency. To gauge the feasibility of this approach, consider the synthesis of dimethyl carbonate (DMC) from methanol and CO2 at 350 K. (a) Write a balanced stoichiometric equation for this reaction. Highlight any by-products. (b) Estimate the Ka value for … Read more
