Aplicacion del proceso Merox Caustico al GLP para eliminar los mercaptanos previo a su comercializacion en refineria La Libertad.
The purpose of this research work is to carry out the compilation of all the basic information necessary to analyze the application of the Merox Process. This process is used to convert mercaptans that are distributed in distilled to disulfides by oxidation, using the merox catalyst to accelerate the reaction. This work focuses specifically on the LPG produced at La Libertad Refinery. The system is made up of two parts from which all the data is collected to carry out the design of the plant. The organic part is the distillate containing the low molecular weight mercaptan to be treated and the aqueous part is the caustic soda solution necessary to carry out the extraction. It is necessary to eliminate mercaptans because they are corrosive to metals, they can cause oxidative deterioration and their odor is very strong. To this end, extractive sweetening processes are applied. In this way, the national and international quality standards and the INEN 675 standards are met. The information available on the Merox Process Caustic applied to the LPG was reviewed and fieldwork was carried out by visiting the La Libertad Refinery plants to collect the data needed for the design.In addition, the basic specifications of the Merox Process Caustic applied to LPG were formulated. The PFD and P ID of the plant were developed, so that technicians, engineers, and specialized operators understand the process better. Key words: Application Merox process Mercaptans
