Talara refinery has a heat exchanger networks in its different units that allows it to take advantage of the heat of its currents to a certain point; however, the scope of the present investigation is the streams and exchangers of the Primary and Vacuum Distillation Unit. Talara refinery does not have a study that let it optimize as maximum as possible the hot streams of its units, so a study of this type this would contribute to have an efficient energy matrix, reduce the energy consumption, reduce the carbon footprint and generate higher profits. For the development of the thesis the Pinch Analysis was used, following the guide proposed by Ian C. Kemp [10] in his book “Pinch analysis and process integration - User's guide on the integration of processes for the efficient use of the energy “- 2nd edition, 2007 The preliminary analysis, doing a mass and energy balance, shows that 21.9 MMBTU/h of the hot streams are lost in the Primary Distillation Unit, and 8.5 MMBTU/h in the Vacuum Distillation Unit. After performing the Pinch Analysis, it was determined that with the optimum ΔTmin, for each unit and its respective applicable streams, the hot streams would be taken full advantage, so the use of chillers is relegated. The results of the proposed retrofit for each unit show that, for the Primary Distillation Unit, energy consumption would be reduced by 27.4 MMBTU/h in the worst scenario and 58.6 MMBTU/h in the optimum scenario, which would generate an economic saving of 1.63 MMUS$/year in the worst scenario and 3.38 MMUS$/year in the optimum scenario, and for the Vacuum Distillation Unit it would save 10.6 MMBTU/h in the worst scenario and 20.9 MMBTU/h in the optimum scenario, which would generate an economic saving of 346.9 MUS$/year in the worst scenario and 683.9 MUS$/year in the optimum scenario.
