1977 Screening Survey for Measurement of Organic Priority Pollutants in Petroleum Refinery Wastewaters

Abstract USS 5, Type 501, and 5S, Type 502, contain approximately 5% chromium and 0.50% molybdenum. They resist corrosion and oxidation at elevated temperatures and are particularly adaptable to applications in the petroleum refinery industry. Type 502 contains slightly lower carbon and is used for applications where better weldability is required. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-22. Producer or source: United States Steel Corporation.

Data of the Federal Information Fund for Social Hygiene Monitoring conducted on the basis of the Federal Center for Hygiene and Epidemiology of Rospotrebnadzor have been analyzed to assess environmental risks, as well as to develop environmental safety system as a factor for sustainable development of the territory in the regions of the Russian Federation. Atmospheric air pollution in Russian regions was evaluated by content of priority pollutants. Ranking of Russian regions according to the quality of drinking water supply was carried out. The possibility of using Federal Information Fund for Social Hygiene Monitoring as an integral part of the model for optimizing the social and environmental conditions of populated areas is estimated.

Abstract Based on discussions in workshop sessions, several recurring themes became evident with respect to the optimization and control of petroleum refinery wastewater treatment systems to achieve effective removal of toxic contaminants. It was apparent that statistical process control (SPC) techniques are finding more widespread use and have been found to be effective. However, the implementation of real-time process control strategies in petroleum refinery wastewater treatment systems is in its infancy. Considerable effort will need to be expended to demonstrate the practicality of on-line sensors, and the utility of automated process control in petroleum refinery wastewater treatment systems. This paper provides a summary of the discussions held at the workshop.

Aerobic Sludge

Abstract Aerobic sludge from a municipal activated sludge treatment plant, sludge from a conventional municipal anaerobic digester, aerobic sludge from an activated sludge process of a petroleum refinery, and granular sludge from an upflow sludge blanket reactor (USBR) were tested in the deemulsification of a water-in-oil emulsion. All sludges except the last one, showed a good deemulsification capability and could he used for a partial deemulsification of such emulsions. The rate and degree of the deemulsifications increased with an increase in sludge concentrations. The deemulsifications were faster at 85°C and required smaller amounts of sludge than in the case of the deemulsifications at room temperature. An extended stirring (up to a certain limit) in the course of the dispersion of sludge emulsion helped the deemulsification. Too vigorous agitation had an adverse effect. The deemulsification effect of sludge became less visible with an increase in the dilution of emulsion which caused an increase in its spontaneous deemulsification.
