ABSTRACT: The technique of modeling operating temperature variations of shell-and-tubeheat exchanger 10-E-01 of kerosene-crude oil streams of Port Harcourt refinery crude distillation unit is presented in this research. Appropriate first-ordermodel equations were developed applying principles of energy balance. The differential equations developed for the process streams which exchangedheat was evaluated numerically to predict the temperature variations as a functionof time. The relevant parameters associated with typical heat exchanger works were calculated using plant data of 10-E-02. The model strives to predict the final kerosene temperature from 488 to 353.6K. While the crude oil streams temperature rose from 313 to 353.6 K. The developed model enables the operator to predict the final temperature at the kerosene hydro-treatingunit and thereby prevent regular emergency shutdowns due to excessivetemperature rise.
