Estudo da eficiência dos sistemas microemulsionados na recuperação de petróleo, utilizando como matéria prima o oleo de coco saponificado.

Abstract

Oil is undoubtedly the main source of energy. And an oily substance, formed from organic matter as substances coming from the surface of the land, when deposited on the ocean floor, under high pressure thousands of years converting to oil. Currently one of the main problems faced by the oil well drilling industry in terms of respect to the oil recovery processes, consists of the issue of separation of the oil oil and water that is emulsified with the oil, after being extracted from the well. In view of this, the well drilling industries resort to methods of oil recovery. In this work, the systems method was used micro emulsified (SME), classified as a tertiary method. This method uses the surfactants as raw material in the preparation of microemulsions, in which they have the purpose of reducing the interfacial tensions between water and oil, expanding the displacement efficiency. This work aims to study the efficiency of micro emulsified systems in oil recovery. To obtain the points microemulsions, a study was carried out, where these points contain the composition of the following components 1st Point: oily phase (Kerosene-10%), aqueous phase (Water distilled-10%), surfactant (64% isopropyl alcohol), surfactant (OCS-16%; 2 ° Point: oily phase (Kerosene-20%), aqueous phase (distilled water-10%), surfactant (56% isopropyl alcohol), surfactant (OCS-14%); 3rd Point: oily phase (Kerosene 30%), aqueous phase (distilled water-10%), surfactant (48% isopropyl alcohol), surfactant (OCS-12%); 4th Point: oily phase (Kerosene-10%), aqueous phase (Water distilled-20%), surfactant (Isopropyl alcohol 56%), surfactant (OCS-14%).
