Apparatus and method for the determination of phase behavior in pressure systems.

摘要

Apparatus and method for the determination of phase behavior in systems under pressure is described an apparatus (100) for the determination of phase behavior in systems under pressure, including oil and its fractions, the apparatus comprising a cell (13) of equilibrium with The internal piston (140 and display system through windows of sapphire (13b), (13C).An NIR probe (11) for making the spectra in the region of the near infrared being coupled to said cell (13), and a NIR spectrophotometer (18), and a personal computer (19) for the treatment of spectra and storage of images collected from the system. The method of determining the behavior of phases in these systems with the aid of said apparatus is also described.
