Determination of the Dependence of Power Consumption of the Main Pumping Unit on the Volume of Technological Mixture of Petroleum Products During Their Transportation by the Method of Sequential Pumping With Direct Contact

The article is devoted to identifying the relationship between power consumption and the amount of process mixture formed at the points of contact of different types of petroleum products during transportation through a main petroleum product pipeline using the method of sequential pumping with the fluid speed as an intermediate parameter. At the first stage, it is necessary to determine the dependence of the volume of the process mixture on the speed of movement of the petroleum product, which allows assessing the possibility of distributing the process mixture into tanks at the final point in accordance with the volume of the tank farm. At the second stage, the dependence of power consumption on the speed of movement of the petroleum product is determined, which creates conditions for estimating the energy costs of transporting petroleum products. At the third stage, the dependence of power consumption on the volume of the process mixture is determined, which informatively helps in choosing the optimal balance between the volume of the mixture and power consumption with the possibility of reducing the pumping speed below the normatively recommended values. The proposed approach for determining the dependence of power consumption on the amount of process mixture is a convenient tool for simultaneous assessment of two parameters and finding the optimal pumping mode.
