Abstract

DIAZ ALVAREZ, JUAN CARLOS et al. STATISTICAL ANALISYS IN THE PREDICTING OF MIXING VOLUME GENERATED BY BATCHING TRANSPORT OF HIDROCARBONS THROUGH PIPELINES. Rev. ion [online]. 2011, vol.24, n.1, pp.23-33. ISSN 0120-100X.

The purpose of this article is to determinate the mixing volumes in batching transfer of distilled fuel and diesel at different admissible concentrations trough multiproduct pipelines. The methodology employed to realize this work consists on both of an own numerical algorithm, which has been supported on MATLAB, and the introduction of a parameter called axial dispersion coefficient. In order to obtain a better coincidence between experimental data by using this methodology, we employed the empirical equation of Sjenitzer to determine the axial dispersion coefficient. This step allowed finding two mathematical expressions which allow obtain a relation between cut's times and the admissible concentrations; thus generating, a significant contribution to the necessary foundations to automatize the separation process and storage subsequent of the fluids which are part of the system in study. Finally, a change in the pipeline diameter given by a predominance of inertial forces over viscous forces in the Reynolds number, produces a higher effect over the contaminated volume in contrast with a pipeline length change or a flow change. These facts were demonstrated with a statistical analysis.

Keywords : mathematical model; axial dispersion coefficient; cut's times; admissible concentrations.
