Previous issue date: 2016-02-19 / O petr?leo ? uma mistura complexa, havendo predomin?ncia de hidrocarbonetos paraf?nicos, naft?nicos e arom?ticos (Freitas e Costa, 1969) al?m de outros constituintes (sulfurados, nitrogenados e oxigenados) que ocorrem normalmente na forma de compostos org?nicos. O CO2, por exemplo, estar presente em mais de 25% do ?leo extra?do da camada do pr?-sal entre as bacias de Campos e Santos. Estimativas apontam que somente nas duas ?reas com reservas delimitadas - os campos de Tupi e Iara, onde h? um ac?mulo de at? 12 bilh?es de barris de ?leo e g?s - existam 3,1 bilh?es de toneladas de CO2, um dos gases que contribuem para o aquecimento do planeta. Devido a essa grande quantidade de contaminantes (CO2, N, S, etc.) presente na mistura de hidrocarbonetos extra?da dessas bacias, ? preciso buscar novas pr?ticas de separa??o deste contaminante. Para tal desenvolvimento de novas pr?ticas ? importante um estudo constante sobre o equil?brio termodin?mico entre os constituintes do petr?leo e seus contaminantes. Com isso o objetivo ? construir um equipamento que gere condi??es suficientes para poder verificar o comportamento de fase de v?rios sistemas de interesse da ind?stria do petr?leo com seus contaminantes mais comuns, por exemplo: CO2 a alta press?o utilizando o conhecimento pr?vio do grupo Neto, 2010 de pesquisa, que deve operar em press?es e temperaturas de at? 300 bar e temperatura at? 100 graus Celsius. Alguns sistemas de interesse s?o: CO2 e alcanoaminas (monoetanolamina, dietanolamina, trietanolamina). ?gua e ?lcool laur?lico etoxilado e CO2 e alcanos com leve contamina??o de ?gua. / 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.
