Abstract
Despite the great concern about the environment and a growing search for sources of clean and renewable energy and raw materials, there is a great and increasing demand for the use of crude oil and it’s derivatives. Water and oil are in contact in various industrial processes, whether directly connected to the extraction and refining of crude oil or not. Even with all care in the separation between water and oil, spills may occur and there is a need for research to contain or clean up polluted ecosystems. Even though oil is immiscible with water, in practice it is very common to find it in the form of emulsion what has been considered a complicating factor both technically and financially to various industries in various sectors. Effluents must be discarded according to the legislation. The aim of this work is to create a simple, fast and efficient method of cleaning oily water. Oil and used mineral insulating oil were tested in dry sorption system (water-free) and in stirred aqueous systems with natural woven fibers used as sorbent materials and compared to a commercial product of polypropylene in the form of mats. Two types of fibers were tested, vegetable (chorisia speciosa) and animal (white poodle fur and a mixture of dog fur from different dog breeds), waste of establishments that provide care to animals. The mixture of dog fur was statistically representative of the samples obtained in pet shops.
