Caracterização do petróleo no software HYSYS

Abstract

The oil was characterized in the software, where the input data are volume of liquid x boiling temperature, volume of liquid x specific density and amount of light (methane, ethane, propane, butane, etc.), in which has a distillation curve and make the cuts under the track temperature. Each oil has its distillation curve. There are several methodologies for construction of the distillation curves, such as ASTM D-86, ASTM D-1160, ASTM D-2887, and they differ as pressure and temperature used, product and type of apparatus. The "Oil Environment” (HYSYS) provides the introduction of input data where the characteristics of the oil can be represented by using hypothetical components. The method of characterization in HYSYS converts its analysis of crude oil in a series of hypothetical components. The program produces a full group of physical and critical properties for hypothetical components with a minimum of information. From the curve with the input data, the software generates the other curves (ASTM) by correlations. This also generates a graph of the distribution of volume fractions as a function of temperature of each fraction.
