Main source: Separations Process Engineering, 4th Ed., by Phillip C.Bubble Point Curve-the curve that separates the pure liquid (oil) phase from the two-phase (natural gas and oil) region. Third: to answer your question about condensation and performance, it is not necessarily a good idea to run a vapor-liquid mixture through compressors although it certainly can be done. As my senior design professor would say, 'Compressors will eat your lunch.' Second: Compressors are expensive both in terms of capital and operation.

You could try figuring the software out yourself, but you are better off asking one of you ChE friends for help.ДЄs for compression, keep a few things in mind:ДЇirst: that adiabatic compression a gas will cause heating meaning that a compressed gas will only condense if you cool it down Aspen is a simulation software that may be available on the computers in your universities ChE department.

Read values of K from where the ruler intersects with component line.ДЄlternatively, you might find Aspen Plus helpful. On using the Depriester chart: set ruler so that one end lines up with the appropriate T and the other end lines up with the appropriate P. Since you are solving for T which is not explicitly defined in this equation, you will need to either use trial, error, and the DePriester chart to find T or find the DePriester chart in equation form and solve that set of equations (Wolfram or Excel Goalseek). Use the respective mole fractions for the y's. To be clear, the parentheses indicate that K is a function of T and P, not any arithmetic. To finding the dewpoint solve the following equation: The DePriester chart does not include nitrogen, but it is probably safe to assume its K is effectively infinity for the conditions you are using since its boiling point is much lower than the other components. Where y and x are the mole fractions of that component in vapor and liquid respectively. Section 5 has information on dispelling some of the assumptions I mentioned above.ДЇor methane and ethane, you can use a DePriester Chart to determine the vapor/liquid equilibrium ratio of each component for any temperature and pressure. This problem can be as involved as you want it to be.Д®dit: Here is a nice little summary for the uninitiated. There are more corrections to be had if you want to eliminate some assumptions. This is, in my view, a thermo for Chem E's probablem. You want a lowish pressure (which you have) and really similar components (methane & ethane) to be more confident in this assumption, but my intuition says that nitrogen will probably play well with them. You can probably get away with assuming ideal gas/liquids and using raoult's law. There might be something available since these are all pretty standard chemicals, but I'll leave that to you. You can google around, but as systems grow more complex it gets exponentially more unlikely to be able to find nice experimental data to make your life easy. No, you can't simply consider how the substances behave in isolation and choose the highest dewpoint.
