RESUMO:

The petroleum industry has an indisputable importance in the contemporary scenario, mainly due to the fact that petroleum is an indispensable input for several industrial sectors such as textiles, automobile, chemical, agricultural, etc., if a raw material of difficult replacement, in the short term, in the energy matrix of any country. However, besides generating derivatives of primary importance, activities such as drilling, production, transportation, processing and distribution generate solid and liquid waste in the form of sludge, lees, liquid and gaseous effluents, among others. In this context, it is essential to reduce, apply, use, treat and appropriately dispose of such waste in accordance with environmental legislation. One such effluent is produced water or production water (PW), which is present in the oil and natural gas reservoirs and is brought to the surface along with the oil. This water, which is found in Petroleum Effluent Treatment Stations, has in its composition important levels of harmful substances, thus preventing waste, reuse and injection without proper pretreatment. The chemical composition of the AP varies over a wide range and depends mainly on the attributes of the reservoir geology. This composition may also change slightly over the life of the reservoir production. AP treatment is technically feasible and economically reasonable. However, there is still no complete treatment for it, because of its large volume and cost, since numerous separation processes are required for effective treatment. Approximately ninety percent of PA during hydrocarbon production is either injected into the well or discarded in the ocean, but due to shipping and disposal costs, deep injection is extremely expensive. In the last decades, great importance has been given to the study of surfactants and microemulsion systems (MES) in the treatment of PW, because they have a high solubilizing power of both polar and nonpolar substances, high interfacial areas and stability. In this context, the present work aims to contribute to the development of methodologies for the treatment of oily produced water (OPW) using microemulsified systems.
