    Análisis de las simulaciones del proceso de deshidratación del gas natural con Aspen Hysys y Aspen Plus
    (Universidad de Cuenca, 2015-09) Benitez, Leonel Alberto; Gutiérrez, Juan Pablo; Ale Ruiz, Liliana; Erdmann, Eleonora; Tarifa, Enrique
    Natural gas has taken an important strategic role in world energy supply as a result of the growing global energy demand. Water is probably the most undesirable component found in raw natural gas because its presence can produce hydrate formation, and it can also lead to corrosion or erosion problems. Due to these often expensive consequences natural gas should be subjected to conditioning processes in order to achieve strict specifications for sales, transportation and final uses. In recent years, process simulation is playing an important role in the oil and gas industry as an appropriate and powerful tool for the design, characterization, optimization, and monitoring of industrial processes performance. In this paper the development of two steady state simulations of natural gas dehydration by absorption with triethylene glycol (TEG) is described, using commercial process simulators such as Aspen HYSYS V8.3 and Aspen PLUS V8.2. Natural gas composition, plant configuration and operating conditions adopted for designs and simulation are those generally used in the area in conditioning plants of natural gas in the province of Salta (Argentina).

    Diseño del proceso de una torre de vacío. Ventajas de la simulación
    (Universidad de Cuenca, 2015-09) Vega, Macarena; Ale Ruiz, Liliana; Martínez, Julieta; Erdmann, Eleonora
    Heavy hydrocarbons are the greatest oil resource in the world, however in the past had been put aside as an energy resource due to the difficulties and costs associated with production, [1]. Nowdays, the industry is financing this research because of the importance of production and the characterization. To analyse the vacuum tower, we need ASTMD1160 temperature at 10 mmHg and oil density, thereafter it can be obtained the curve of TBP760 (True Boiling Point). To correlate different boiling points with vaporized percentages for each change of pressure on the products, is necesary to build up a phase diagram with the EFV760 (Equilibrium Flash Vaporization) and EFV10 temperature. The simulator through internal calculations resolves the phase diagram, compared with the difficulty posed by manual calculations. In this paper a vacuum tower simulator is developed by Aspen HYSYS V8.3, and using the heavy oil as input data. The major advantage of the theoretical designed simulation process is the time resolution
