RESUMO

Natural gas, like petroleum, is a non-renewable energy resource and has been used commercially for more than a century. Natural gas does not have a unique composition, it is a mixture of light hydrocarbons, mainly methane, and other organic and inorganic substances in smaller quantities, that in some cases need to be removed. With the aid of the HYSYS process simulator and the MINITAB statistical software, it was possible to develop studies for characterization, treatment and optimization of natural gas processes. The characterization consists in determining the properties of both pure components and a natural gas stream, elaborate thermodynamic diagrams and predict if there is hydrate formation or noto For the treatment, first, the acid gases need to be removed in a process known as "sweetening". Next, liquid water, or in the form of steam, has to be removed in a dehydration processo These processes are fundamental for natural gas treatment because, for its commercialization, the gas has to meet rigorous specifications of H2S and water contento Factorial design and Response Surface techniques were used for the optimization of the natural gas treatment processes. These techniques allow one to predict, with a high degree of confidence, the operating regions for each variable, in which the required specifications for the gas
