• Abstract:

  Brazilian offshore production is greater than onshore production and therefore deserves to be highlighted in its analysis. In recent years, offshore oil exploration in the Brazilian pre-salt has gained prominence due to its volume and social contribution to the country. As it is a complex process, it is important to simulate and model the conditions imposed on the equipment as accurately as possible. The exchangers of FPSOs in platform processes are mostly of the shell and tube type and therefore deserve attention. It was in this scenario that models and simulations were developed to control shell and tube heat exchangers in order to evaluate optimization conditions and possible process stability scenarios. The scheme proposed by Garcia's work was used as a basis and simulated in the Matlab® Simulink® environment in order to validate the models with real data from the studied platform. The results were satisfactory, with deviations of less than 10% for the variables analyzed and it was possible to validate the Gracia model by comparing it with the theoretical and real data available.
