Artigo:

Processium (French company newly implemented in Brazil) and the Centre Thermodynamic of Processes present a new apparatus based on a ―static-analytic‖ method, capable of measuring P-T-x-y data in the [0.05 - 10] bar and [-30 - 200] °C ranges. This is possible due to a new in-situ sampling mechanism allowing for operations at both vacuum and pressurized conditions without breaks, or losses in accuracy. The equipment was tested against other classical low pressure VLE techniques on the binary systems n-butane + ethanol and n-pentane + 1-butanol. The new developed technique is shown to offer comparable, if not superior, performances to existing methods, while being able to cover a pressure range previously not possible using a single technique.
