Abstract :
Exergy analysis incorporates the precepts of both quantity of energy and quality of energy, so it´s a powerful tool used for analyzing and improving the efficiency of chemical and thermal processes. The network algebra of input-output analysis provides a rigorous way of analyzing the industrial sector quantitatively. This paper uses a thermodynamic input-output model of the 2007 Hubei province economy that accounts for the flow of cumulative exergy in the 42-sector benchmark economic input-output model. We find that the energy supply sector, petrochemical sector and utility sector have the highest cumulative exergy. Coal is the primary energy in consumption, we should raise the efficiency of the coal combustion to reduce the total energy use.
