Abstract: To the batch transportation of cool and hot crude oil, the total cost of transporting oil consists of fuel cost of fire furnace and power consumption cost of oil pump. It is very important to make the total consumption minimal under the premise of accomplishing safely transporting task. Taking the minimal of total energy consumption as the objective function, a batch transportation model of cool and hot crude oil pipeline was set up. The batch transportation in the model was divided into four time stages that unsteady stage of the cold oil head heated, quasi-steady-state stage of the cold oil unheated, unsteady stage of the cold oil end heated and quasi-steady-state phase of the hot oil heated. Two-layer nesting method was used to solve the quasi-steady-state stage; both two-layer nesting method and meeting the pitted in-station temperature of oil head (oil end) were used to select the optimization scheme. Combined the engineering practice, the optimization example of the batch transportation of cool and hot crude oil was given, and the research results can provide a decision-making basic for optimizing transmission of the batch transportation of cool and hot crude oil.
