Petroleum is an indispensable resource in development, and its main component is a mixture of various alkanes, naphthenes, and aromatic hydrocarbons. Oil is a non-renewable resource. Oilfields produce a large amount of sludge during the process of extraction, storage, gathering, transportation, and processing. These sludges have high water content and large volume. They contain not only petroleum resources but also a large amount of radioactive elements. Causes severe impacts and threats to the environment. Therefore, from the perspective of economic and environmental protection, the reduction, harmlessness, and resource treatment of sludge will become an inevitable trend, which is conducive to promoting the sustainable development of a circular economy and society.
According to the formation of oil sludge, it can be divided into ground oil spill, floor oil sludge, tank bottom oil sludge, and oily sludge in refineries. Due to the diverse nature and complex types of sludge, most sludge is a mixture of water, mud, oil, and other impurities, which is difficult to handle. At present, the sludge treatment methods mainly include coking technology, pyrolysis treatment technology, solvent extraction technology, dewatering technology of sludge quenching and tempering machinery, ultrasonic deoiling technology, profile control technology, and hot water washing treatment technology.
China, as the world ’s largest developing country and a large energy consumer, has learned from foreign advanced levels in recent years, developed independent products, and made great progress in sludge treatment. It is hoped that through continuous development and progress, sludge will be more appropriately treated.
According to the characteristics of oil sludge and the technological requirements of oil fields, our company has successfully applied the oil sludge processing equipment to Daqing oil field and Shengli oil field with high technology maturity.
