Opis:
Purpose: To improve the technologies of different oil types of sequential pumping through the pipeline by establishing the laws of changing the throughput and energy efficiency of the oil pipeline operator in the process of pumping and displacing oil batches. The identified regularities would contribute to more effective management of the mixture realisation process at the end of the oil pipeline and reliable forecasting of the results of the different oil types of mixture formation. Design/methodology/approach: Carrying out theoretical studies and applying mathematical modelling methods in order to establish the regularities of hy-drodynamic processes during the injection into the oil pipeline and the displacement of oil different grades from it. Findings: The regularities of changes in oil pipeline capacity and specific electricity costs for transportation as a function of the coordinates of different oil types of batches contacts and the time of sequential pumping cycle implementation they have been established. Research limitations/implications: The next stage of the research is to establish the influence of the hydrodynamic processes features on the intensity of the oil different grades mixture formation in the process of their successive pumping in the oil pipeline. Practical implications: A method and software have been developed that make it possible to predict the throughput and energy efficiency of oil pipeline operation for each moment of the sequential pumping cycle of small batches of different grade oil. The application of the method for the conditions of an operating oil pipeline proved that during the cycle of four types of sequential oil pumping, the change in throughput exceeds 20%, and the change in energy consumption exceeds 10%. Originality/value: The originality of the method consists in taking into account the regularities of the hydrodynamic process of the movement of several batches of oil of different grades in the pipeline, the features of the profile of the pipeline route and the physical properties of the liquid that fills the cavity of the pumps.

Opis:
Purpose: Improving the technology of cleaning the inner surface of the main oil pipelines from paraffin deposition by specifying the hydrodynamic parameters of the movement of the cleaning device in the cavity of the pipeline, by more accurate prediction of the time of its approach to the final point of purification. Design/methodology/approach: Performing theoretical researches and application of mathematical modelling methods in order to establish the regularities of the cleaning device movement in the oil pipeline. Findings: Regularities of changes in the capacity of the pipeline, the speed of the cleaning process, the specific energy consumption for oil transportation as a function of the linear coordinates of the place and time of the cleaning device movement in the pipeline were established. Research limitations/implications: The next stage of research is to establish the influence of the characteristics of the viscoplastic fluid of the paraffin plug on the additional resistance and the mode of the cleaning device movement in the pipeline. Practical implications: It was developed the method that allows predicting the capacity and energy efficiency of the pipeline operation for each point in time of the process of cleaning from paraffin deposition. Originality/value: The originality of the method is the taking into account the additional hydraulic resistance of the paraffin plug and the available energy resources of oil pumping stations on the hydrodynamic process of moving the cleaning device in the oil pipeline.
