Prospects for the effective use of fly ash in the technological processes of oil and gas production

Abstract

The problem of efficient use of coal fly ash (CFA) is a global environmental problem that requires urgent attention and immediate action to address it. Research shows that huge amounts of CFA are generated every year, but only 25% of the waste is recycled. To overcome this alarming situation, there is a need to focus on increasing the use of coal ash in various industries. The promising uses of coal ash in construction, electronics, resource recycling, wastewater treatment, agriculture and other industries require further research. Of particular interest is the use of coal ash in industrial processes for the extraction of hydrocarbons. The physical, chemical and mineralogical properties of ash, such as its morphology, surface area, porosity and chemical composition, make it an ideal material for various field processes. Increasing the use of coal ash in various industries and its use in industrial processes for the extraction of hydrocarbon raw materials will significantly increase the level of utilization and reduce the negative impact on the environment.
