Dear Dr. ………….,
This experiment aims at determining carbon (IV) dioxide bubble and dew points as a single component by the use of PVT stimulator at four distinctive temperatures. Besides, it determines the increasing of pressure effect on the carbon (IV) dioxide two-phase envelope. The starting pressure was set at two thousand psi with a (±0.1 psi precision. The beginning volume for carbon (IV) dioxide gas was set at zero while the liquid carbon (IV) dioxide at 14.7 cc with a (±0.001) cc precision. On the other hand, four temperatures were set at 79.7℉, 72.5℉, 77.0℉ and 75.2℉ with a (±0.1)℉ precision. All four temperatures were kept constant throughout the experiment period.
It was observed that at 75.2℉ the volume …show more content…
Engineers may be working with PVT data, but sometimes they are unaware of experimental procedure follow to get these data. Individuals dealing with PVT data need to comprehend how the PVT experiments are conducted and its limitations. The behavior of phase experiments can be done by the use of physical or real PVT apparatus/ PVT stimulator. PVT stimulator is a user-friendly computer program which triggers the real world situation. PVT stimulator is applied when one wants to observe fluids’ behavior under temperature, pressure and volume changes. A computer program was used in this experiment to imitate the real world state. The phase behavior was calculated using the Peng-Robinson Equation of the state which is used by PVT simulator as shown …show more content…
The visual cell has a capacity of 100cc. The chamber is described as visual cell because it has a window that one can use to investigate phases or fluids. Furthermore, the visual cell has a gas or fluid of interest. The visual cell is designed in a way that it withstands high experimental temperatures and pressures. Usually, a component is transferred from charging container into the cell by hand pump. Hand pump first creates space in the cell, followed by pushing the fluid of interest from charging vessel into the cell (Figure c). Mercury is applied in the system to displace fluids; it functions like a solid piston which has been triggered by hand pump. Hence, mercury does not interact with the fluid. When a component (single or mixture) is introduced into the cell, component volumetric characteristics are investigated by withdrawing or injecting from the
