Currently, the issues of energy saving and environmental safety at fuel and energy facilities are becoming urgent. The article presents a new installation designed for oil waste processing and water-oil emulsion production. The resulting emulsion can be disposed of by combustion. At the same time, oil waste storage areas and emissions from waste storage to the environment are significantly reduced. Also the combustion of water-oil mixture reduces emissions to the atmosphere compared to the incineration of waste, without water. Oil-water emulsion is a mixture of oil waste and water in certain proportions. The article presents the design and principal scheme of the plant for obtaining oil-water emulsion. Operation modes of the developed installation are studied. The results of the water content evaluation in the mixture are given. Experiments were performed on a model of fluid with a viscosity of mazout. This installation has three circulation loops. Each loop has a device for mixing and producing a homogeneous mixture. The loop can operate independently from each other or together. According to the obtained results, the most effective circulation scheme is a scheme that includes all the devices of the installation. The results of the experiments revealed that the stability of the mixture requires water content within 20–25 %. At concentrations more than 25 % a speed of steady-state achievement is lowered. At concentrations less than 20 % this speed is high, but emulsion rapidly decompose into components. Also the article describes the concept of a mobile installation for oil waste disposal. The scheme of stand is considered, the offered arrangement of the equipment is given. This installation will allow to collect local oil spills and oil waste, process and transport it to the place of their burning with the least expenses.
