摘要：

In this paper, the rationality of energy use is evaluated from the perspective of energy quality for the heating and temperature maintenance process of large floating roof crude oil storage tanks. The multi-link correlation analysis model of heating and temperature maintenance process of storage tank is constructed, and the variation law of phenomenological characteristic index group of exergy transfer is analysed. Three evaluation indexes of exergy resistance rate, exergy loss rate and sensitivity factor were determined and evaluated by TOPSIS method. The results show that the energy consumption from coil to oil is the weakest.
