BUBBLE-POINT PRESSURES OF SOME SELECTED METHANE PLUS SYNTHETIC C6+ MIXTURES

In this work, a series of bubble-point measurements were carried out o n some synthetic C6+ mixtures in the presence of methane. These synthe tic mixtures included alkanes, cycloalkanes, and aromatics. The experi ments were carried out using the Cailletet apparatus, and bubble-point pressures were measured in a temperature range of 311-470 K. The corr esponding pressures were predicted using the Peng-Robinson equation of state, and the relative errors were estimated. It is shown that such synthetic C6+ mixtures can be simulated reasonably well by this equati on of state.
