Abstract
This paper presents a study on the heating system of asphalt storage tanks at an oil refinery. The study evaluates the efficiency in three thermally insulated tanks and with a steam coil heating system that are running poorly. Heat transfer studies to determine the thermal load as a function of external and storage temperatures were correlated with the energy supplied by the steam heating system. The results show that the current system cannot maintain the temperature in the initially designed conditions and an energy cost analysis shows that the asphalt must be stored at the highest possible temperature and use an auxiliary heat exchanger to reach the ideal pumping temperature. The design of the auxiliary heating system determined a thermal capacity of 631 kW with a thermal exchange area of 83 m2.
