PROPOSAL OF SOLUTIONS FOR DIELECTRIC OIL PRODUCTION RESIDUAL IN SERGIO SOTO REFINERY

Abstract

In this research possible variants of separation were identified and tested such as evaporation, centrifugation and precipitation for the treatment of waste water resulting from dielectric oil production in Sergio Soto refinery of Cabaiguán, Sancti Spíritus. This waste water with intense dark color and strong smell of hydrocarbon is released into water courses and in this way, deteriorating their quality and preventing the oxygen dissolution and its decreasing due to oxidation of organic matter. It seriously disrupts the development of aquatic life and water use for domestic purposes. Precipitation variant is proposed, using ethanol as a solution for separating the residual in two phases (liquid and solid). A theoretical explanation is giving to understand this separation. Both phases were characterized. Treatments for liquid phase are proposed and the fuel-oil with solid mixture is tested to be reused following Cleaner Production.
