The subject of this article is a study of the use of an oil separation unit based on a combined-engine separator, a comparative economic calculation of the energy efficiency of a separator engine versus a classical design separator at oil and gas facilities.
The article describes in detail the method of oil separation based on the use of a combined design according to the engine-separator scheme, as well as the design of the engine-separator and the principle of its operation. In the separator motor the separator drum performs two functions: a device where the process of oil separation fr om third-party products takes place and the rotor of an induction motor. In the proposed design, the losses in the rotor-separator drum are used as heating losses to heat the product of separation in the separator drum, and the energy losses released by the core and the stator winding of the separator motor are used to preheat the separation product. The calculations are made in relation to the three types of separators and oilfield capacity, wh ere the separation needs to be done.
The calculations described in this paper demonstrate that due to the use of a separator of a combined design according to the engine-separator scheme, it is possible to obtain energy savings of up to 5% if the separation product is preheated.
The results of the research can be applied to the calculation and design of power supply systems, including for remote oil and gas facilities.
