Abstract |
Supercritical fluid has excellent dissolving power for various materials based
on low viscosity and high diffusion coefficient and is used as solvents in various
chemical processes. However, its industrial application can be very tricky because the
design, especially the size of the supercritical apparatus, should be carefully chosen to
optimize the cost and the production of supercritical fluidic state. And the first step of
the supercritical fluid apparatus design is to choose the appropriate size of the reactor
vessel to produce supercritical fluid above its critical pressure and temperature.
Therefore, this study aims to analyze thermodynamic behaviors of dichloromethane
based on ideal gas, van der Waals, Redlich-Kwong, Soave-Redlich-Kwong, and
Peng-Robinson equations of state. The correlation between the volume and pressure of
dichloromethane at 200¡É was revealed and it can be used to design the optimized
size of the supercritical apparatus for industrial production. |
