Exergy in technological separation processes
Original language description
The exergy concept applied to technological separation processes has been presented and discussed in detail. Especially the building of thermodynamic effectivity quotients has been emphasized. Two main separation processes have been analyzed in detail. They are the rectification process and the extraction. The last one is not that important for the power engineering, but while analyzing it a special behavior of the exergy can be discussed. It depends not only on one parameter (temperature, pressure or concentration), but on two parameters (amount of the substance and its concentration). Thus, the special procedure of partition exergy changes into vanishing and created exergies (i.e. thermodynamic expenditures and advantages in a process) could be presented. Two numerical examples for the rectification have been calculated and one such an example for the one?stage and two?stage extraction process.
