And Storage

The contamination of water and soil by petroleum hydrocarbons is reported quite frequently, mainly due to accidents involving transport and storage of fuels. Among the most toxic compounds the most volatile benzene, toluene, ethylbenzene and xylene (BTEX). Residues of these compounds can cause serious environmental and public health troubles. Thus, more sensitive, selective and low-cost techniques, focused on the analysis and monitoring of these contaminants are being developed in order to establish operational control and to comply with local laws, but the intellectual property of such technologies is still unknown. The present study shows the panorama about patents, thesis and dissertations which have been already published on this theme. Together, the United States and China hold the largest number of patents, and most of thesis/dissertations describe methodologies for BTEX detection in water, although numerous environmental problems caused by oils in the soil had been reported. Also, the methods based on chromatographic techniques stand out in relation to the other techniques. It was possible to verify important advances in the field of sensors, especially the electrochemical ones, in order to solve the analytical gaps.

Clear Solution

Direct analysis of oily water effluents was investigated as a method for the determination of petroleum hydrocarbons in the discharge from primary oil production facilities. A co-solvent, isopropanol (2-propanol), was chosen that produced a clear, homogeneous solution when added to oil-in-water effluent. The clear solution was then analyzed directly for aromatic hydrocarbon content by using ultraviolet spectroscopy. The concentration of oil in the sample was calculated from a Lambert–Beer plot at 226 nm. The standard used was a sample of oil that best represented the oil that had contacted the water, i.e., current production crude oil.
