Strategies in Petrochemical Processes Part-I: Case of Peruvian Oil Abstract The great importance of oil in today’s world economy is based on their contribution the total energy supply. In 2020, the world consumed 91.3 million barrels of oil per day. Depending on the quality of the crude (chemical and physical properties), the different types of oil are commercialized around the world. For two decades ago, approximately, there are tendencies up to lower or free Sulphur fuels (content under 50 ppm) for vehicles in order to reduce the emissions generated. The sulfur content of crudes is important for the determination of commercial values. Peru exports most of their crude, due to this is too heavy in Sulphur content (2000-5000 ppm) for their refineries. Peru has undergone changes in the last three decades that increased the pressure about environmental issues. The Transport is considered one of the main causes of air pollution in several Peruvian cities. For this reason, it is imperative the development strategies in order to reduce the emissions of Sulphur compounds and/or improve the existent chemical processes of petrochemical industry. We present an alternative process design, corresponding to the Sulphur desorption unit for Peruvian crude oil, in order to minimize their content, previous to the distillation units.
