| Resumo: | This dissertation aims to assess the representativeness of the manual chilled mirror analyzer
(model II Chanscope 13-1200-CN-2) used for the determination of condensed
hydrocarbons of natural gas compared to the indirect methods, based on thermodynamic
models equation of state. Additionally, it has been implemented in this study a model for
calculating the dew point of natural gas. The proposed model is a modification of the
equation of state of Peng-Robinson admits that the groups contribution as a strategy to
calculate the binary interaction parameters kij (T) temperature dependence. Experimental
data of the work of Brown et al. (2007) were used to compare the responses of the dew
point of natural gas with thermodynamic models contained in the UniSim process simulator
and the methodology implemented in this study. Then two natural gas compositions were
studied, the first being a standard gas mixture gravimetrically synthesized and, second, a
mixture of processed natural gas. These experimental data were also compared with the
results presented by UniSim process simulator and the thermodynamic model implemented.
However, data from the manual analysis results indicated significant differences in
temperature, these differences were attributed to the formation of dew point of water, as we
observed the appearance of moisture on the mirror surface cooling equipment |
