Reducción del volumen de mezcla generado en el proceso de recepción de interfases de productos limpios diésel-súper y súper-diésel del poliducto Pascuales-Cuenca.

Abstract

This research work aims the integration of sequential control algorithm to the existing control system about the DCS Delta V software, applying the reference method GEMMA and using GRAFCET as process automation tool; the experimental and quantitative method in order to reduce the bulk capacity got by (interphase) product, generated when receiving the diesel-super and super-diesel interphases at reductive station of clean products, Cuenca EP-Petroecuador. The automate process was studied as well as the products characteristics and the obtained facilities; the real time control and supervision of the process trough the SCADA system, allows to analyze the results by means of graphic charts (historic) and letting the operator to interact with the process. The analysis of the obtained data after the integration of a sequential control algorithm, resulted in the decrease of bulk interphase generated in the trust interval of 95% which means TI95%=(40.8;99.1) barrels e TI95%(52.1; 139.8) barrels in diesel-super and super diesel interphases respecively. It was concluded that by integrating the sequential control algorithm with the existing control system, the interphase capacity produced at the reception process in diesel-super and super-diesel interphases of the clean product station, Cuenca EP Petroecuador, has been reduced. As recommendation, the referential API value should be the corrected one at the current temperature of the process in order to be inserted by HMI to the system for stablishing the beginning and end of the interphase.
