Abstract: In the process of crude oil storage and transportation, the traditional heating techniques consume large quantities of oil and gas resources, so it is proposed to adopt the solar photothermal technique to heat crude oil. In this paper, a crude oil heating system coupled with electric heating and heat storage functions and its work flow were designed by analyzing the utilization modes of solar photovoltaic and photothermal comprehensively, combined with the characteristics of large-scale crude oil storage and transportation engineering. Then, the thermal load needed for crude oil heating and the matched condensing area of solar collector system were calculated based on the supply-demand balance of heat energy. And accordingly, the thermal load for the required temperature rise of the crude oil with a certain throughput or storage under special solar radiation intensity and its corresponding mirror field area were obtained. It is indicated that thermal load matching process, equivalent heat supply and energy saving analysis method can improve the overall utilization efficiency of solar energy and provide the reference for the application and popularization of solar utilization technique in crude oil storage and transportation engineering.
