Improving the efficiency of water recycling systems at oil refineries and petrochemical enterprises (part 1)

Summary

Petrochemical enterprises produce a significant impact on the environment; therefore, they are obliged to develop and implement programs to improve the environmental sustainability; the programs have to reflect the compliance of the technological processes, equipment, technical methods, methods used at the enterprise with the best available technologies. Accordingly, the growing demand for practices of improving the effectiveness of environmental protection measures in the operation of specific economic entities stimulates the search and development of new methods as well as particular and integral indicators of the effectiveness of environmental investment projects at various levels. This study presents the results of applying proactive measures related to the implementation of an investment, environmentally oriented project for the reconstruction of water supply and wastewater disposal systems of the enterprise, development of technical measures aimed at improving the efficiency of water recycling systems, reducing the volume of effluents discharged by the plant and reducing the abstraction of raw water from the surface water source.

Improving the efficiency of water recycling systems at oil refineries and petrochemical enterprises (part 2)

Summary

Comprehensive studies were carried out to improve the efficiency of water and wastewater treatment facilities at one of the oil refineries in the Southern Federal District by adding one or more stages of tertiary treatment; by improving the design of the existing facilities; and replacing the technological process of one of the treatment stages for a more efficient one. Research objectives: 1) analysis of the operation of the water recycling systems (units), existing wastewater disposal and treatment facilities; 2) development of the optimal solutions and schemes for upgrading the recycling water supply of the enterprise; 3) development of technical measures aimed at increasing the efficiency of the water recycling system, reducing the volume of wastewater discharged by the plant and reducing the amount of raw water abstraction by arranging the makeup of the existing water recycling units with effluent. The previous article on this topic presented the research materials on the first two tasks.
