Process simulation is a critical step in the identification of areas of energy inefficiencies in industrial facilities. The result of simulation if properly carried out should aid in identifying points of intolerable energy losses in the system. This paper investigated the heat losses through computer simulations. Strategic plans for energy systems efficiency improvement were presented and opportunities for energy savings were also identified. The exact value of heat losses for the heat exchanger is 2720000Kj/h. The adiabatic and polytropic efficiencies of the heat exchanger were found to be 0.86% and 0.79%. A computer software package in Hysys version 3.1 was used for the simulation. From the simulation carried out, it was discovered that the simulation model developed satisfied all the conditions of the empirical model.
