Resumen
Oil is a complex mixture having predominantly paraffinic hydrocarbons, naphthenic and
aromatic (Freitas and Costa, 1969) and other constituents (sulfur, nitrogen and oxygen)
that normally occur in the form of organic compounds. The CO2, for example, be
present in over 25% of the oil extracted from the pre-salt layer of the Campos and
Santos basins. Estimates suggest that only in two areas with defined reserves - the Tupi
and Iara, where there is an accumulation of up to 12 billion barrels of oil and gas - there
are 3.1 billion tons of CO2, one of the gases that contribute to warming. Because of this
large amount of contaminants (CO2, N, S, etc.) present in the mixture of hydrocarbons
extracted these basins, it must find new ways of separation of this contaminant. For
such development of new practices is important a constant study of the thermodynamic
equilibrium between oil constituents and their contaminants. Thus the goal is to build a
device that generates enough conditions to check phase behavior of various oil
industry's interest systems with their most common contaminants, eg CO2 at high
pressure using prior knowledge of Guerra-Neto, 2010, which must operate at
temperatures and pressures up to 300 bar and temperatures up to 100 degrees Celsius.
Some systems of interest are: CO2 and alcanoaminas (monoetanolamine, dietanolamine,
trietanolamine). Lauryl alcohol ethoxylate and water and CO2 and alkanes with mild
contamination of water.
