Abstract: There are optimization calculation results of technological parameters of the high pour point and high-viscosity oil mixtures batching on the Uzen Atyrau section of the Uzen Atyrau Samara trunk pipeline, considering heating, boosting and suction. An optimization criterion is total cost minimum of pumping units and preheaters power consumption. The total cost is calculated according to the tariffs for electricity and heating fuel in the Uzen Atyrau pipeline section. Mangyshlak oil mixture is high pour point oil having a pour point temperature of 27C on the way out of the Uzen main pump station. Pour point temperature of Buzachi oil is 12C. In the thermal regime of high pour point oil pumping the oil temperature in the pipe should be 5C above the oil pour point. This condition determines the lower limit of the search interval for the oil mixture optimal heating temperature equaling to 32C.
The upper limit of the heating temperature at the stations is found by fulfilling the optimization criterion so that the total cost of heating and pumping consumed energy is minimal. The calculation of the batching was obtained under operating conditions of pumping units and preheaters as well as in energy-saving modes of pumping units and preheaters. The results of the calculations show that the effectiveness of energy-saving modes of a batching in the Uzen Atyrau pipeline section ranges from 30.14 % to 32.53 % compared to usual process conditions.

Keywords: trunk pipeline, batching, energy-saving mode, optimization criterion.
