Diseño y simulación de la unidad de hidrodesulfuración de diésel para una nueva refinería

Abstract

ASTM D-86, density, viscosity and sulfur content for diesel standard characterization was used. The input data for the simulation were taken from the mass balance, the same as corroborated by other data streams. It was designed and simulated diesel hydrodesulfurization unit with an initial content of 0.7% by weight of sulfur in the feed, from the atmospheric distillation column. Simulator ASPEN HYSYS V7.3 was used based on the proposed order to obtain the main operating variables, equipment sizing and higher sulfur reduction in the product flow chart for thus reaching the limits set by the INEN 1489. The balance of mass and energy flows in and out in order to size the equipment and get major pollutants and resulting compounds was performed. In addition to the amount of fresh and recycle hydrogen required to achieve process efficiency 94% by obtaining a diesel with a sulfur content of 292 ppm, approaching the standards EURO V. Finally the plant investment was calculated, based on the dimensioning of the equipment.
