ResumoThis paper describes a calculation mechanism obtained from experimental data of ASTM and d20/4 curves to determine the volumetric expansion of naphtha. The study included historical data (experimental) of naphtha from directly distillation samples produced in a Brazilian refinery for a period of one year processing, considering the different loads used for this production. The data selection and calculations were performed at idealized routine in Excel®, with values of process streams. The results were within the ranges indicated by the literature in terms of magnitude, but with deviations of less than 15% of the values listed for consideration in the projects. The adoption of this calculation mechanism is quite simple (as it considers data already available in the refineries’ control systems) and adds a good adjustment for the parameters prediction to be used in design and sizing of safety valves (PSV - Pressure Safety and Relief Valve).
