In this paper, the chemical exergy in waxy crude oil pipeline transportation process was mainly calculated and studied. On the one hand, the specific chemical reaction exergy of waxy crude oil in oilfield was derived according to the common calculation method for fuel chemical reaction exergy, and the calculation results in this paper was proved to be practically available through comparing the results with fuel oil chemical reaction exergy which was calculated by predecessors. On the other hand, the equation of waxy crude oil diffusion exergy was derived according to the common calculation method of chemical diffusion exergy and the mechanism of waxy crude oil diffusion and deposition, the change situation of oil flow diffusion exergy in pipeline transportation process was then studied. The research on this issue aimed at providing a theoretical basis for further study on the analysis of crude oil transportation system exergy. 2017, Science Press. All right reserved.
