An improved calculation of the thermodynamically based allocation of cumulative exergy consumption in petroleum distillation process
One of the most common problems arising from the application of exergy analysis is the allocation of cumulative exergy consumption (CExC) in the petroleum distillation process yielding several useful products. Based on the concept of exergy, an improved calculation of the minimum separation power (MSP) of the product stream in the petroleum distillation process is provided in this article. This method in this paper is an extension of the thermodynamically based allocation of cumulative exergy consumption in the multiple product separation processes where the specific compositions in each of the streams must be known. However, there exist unknown compositions in the petroleum distillation process. The MSP can be derived from the concept of exergy. The related mathematical models are established. Finally, application of this method to a case study is given, and the results are compared with the ones using mass as allocation parameter.
