Abstract
The goal of this article is to present a proposal to optimize the performance of desalinated and dehydrated crude oil in a Colombian refinery, improving the separation of the present phases and ensuring that the salt and water levels in the outgoing crude remain constant and within specifications. First, a diagnosis of the current state of the process is carried out. Then, to evaluate the impact of relevant variables on desalination efficiency, a mathematical model was developed that allows for the reproduction, with a reasonable level of precision, of the actual process values. Based on this model, the optimal operating conditions were determined. It is concluded that the main limitation of the current desalination process lies in the inadequate characterization of the crude load, the low efficiency of the chemical treatment for breaking emulsions, and the high content of salts and hydrocarbons in the wash water. Therefore, it is recommended to redesign the characterization procedures, chemical treatment injection, and wash water handling to improve emulsion breaking and promote coalescence in desalination plants.
