Oil and gas refineries have a significant impact on the environment. The paper considers the main harmful substances formed as a result of the manufacturing processes occurring at the enterprises of the given industry and having a negative impact on the atmosphere, hydrosphere and lithosphere. The most significant sources of contaminants have been identified. The paper presents the most promising approaches described by both domestic and foreign authors for developing environmentally friendly, low-waste productions through the complex use of all the components of raw materials, energy resources and industrial wastes to ensure the required processing conditions. The authors developed and proposed the scheme of the power plant comprising the integrated waste disposal in oil and gas refineries, aimed at combining the processes of the thermal utilization of industrial wastes (combustible gases, effluents) with the processes of gasification and energy production (electricity, thermal energy, synthesis gas, water supply), reducing the specific consumption of the fuel gas for the energy resources production and waste disposal, improving the environmental safety and reliability of the facility.
