Once you have a solution to the exercises you will submit your answers as a PDF by uploading your file to be graded. Initial bubble point temperature of the mixture is 64C (the calculations are not shown here. The rest should be type-written for ease of reading when grading. Take the K-values from the DePriester chart, Figure 7.8(b). DePriester charts in other temperature and pressure units are given by. The scanned pages should relate to using the graphs for solving the problem. Examples of the use of these membrane separation methods are purification of. Important Note: You may submit scanned images or clear handwritten pages as a PDF that is less than 2 MB in size for this exercise.

Examples include bubble point and dew point. Equilibrium constants were taken from the Depriester charts (Figure 8.3, pp. Would the summer, or winter asphalt product be “heavier”? Explain why. An extensive tutorial demonstrates the use of Antoines equation for vapor-liquid equilibrium calculations. calculations to be done using hand calculators, or graphically. Explain which of the following switches will take place in the refinery in about a month, and why? 40 ptsĪ) Switch the deasphalting solvent from propane to pentane.ī) Switch the deasphalting solvent from pentane to propane. In late fall this refinery switches operations to produce more fuel oil from VDR for the coming winter months, producing still some asphalt, but in lower quantity. A refinery in Northwest Pennsylvania produces asphalt as an important product that brings revenue, particularly during the summer months.
