I'm replicating the process from an HYSYS process in which the distillation column, which uses Peng-Robinson for the thermodynamics, works just fine. Any advice on how to address this issues? Web(close enough to a single-phase condition), HYSYS Dynamics will provide good enough accuracy. 2. Incompressible flow: in the case of single-phase fluids, HYSYS uses the Darcy equation for pressure drop calculations. For gas flow at high velocities, compressibility effects become significant causing a deviation from the Darcy equation.

WebFeb 3, 2024 · For gas flow at high velocities, compressibility effects become significant causing a deviation from the Darcy equation. A well-known rule of thumb suggests that if the density (inlet vs. outlet) changes by less than 5%, the gas can be considered an incompressible flow. In those cases, HYSYS dynamics will be a suitable tool. WebMar 5, 2024 · Some experimental values for critical compressibility ( Z c) factors are shown below: CO 2 = 0.2744. CH 4 = 0.2862. C 2 H 6 = 0.2793. nC 5 = 0.2693. nC 6 = 0.2659. The values of critical compressibility factors shown here are relatively close to each other, but, in actuality, they are different. They are, in fact, substance-dependent.
