“…Streams appear at the borders of the subsystem interaction, and the irreversibility increases [10][11][12][13][14][15]. In thermodynamics, this means that the entropy in the whole system increases; in economics, the welfare function of each of the contacting subsystems increases instead [16][17][18][19][20][21].…”

This work states the typical problems in thermodynamic optimization. The authors present an overview of the results of studies focused on the ultimate capabilities of macrosystems in thermodynamics and microeconomics, taking into account the irreversibility of the processes occurring in them. The research methodology is based on adding an entropy balance to energy and matter balances. This allows for the refining of reversible indicators, such as the reversible efficiency coefficient, by accounting for kinetic factors, such as transfer coefficients, which indirectly reflect the size of devices, kinetic equation forms, and others. For processes that use heat energy, the set of feasible solutions within the ‘target flow intensity–energy expenses’ plane is convex upwards and limited. This paper also provides conditions for the minimum dissipation of processes at a given intensity. These conditions define the boundary of the feasibility set. Finally, this paper compares and lists the similarities between thermodynamic and microeconomic systems and demonstrates the ultimate capabilities of an intermediary in microeconomic systems and the optimal parameters of a working medium in thermodynamic systems. These are divided into active and passive subsystems. The latter, in turn, can have finite and infinite capacity (reservoirs).

The bond graph methodology for modelling an integrated energy distillation column is applied in this paper. The distillation column is built by five trays for a binary mixture. However, due to its modular construction in a bond graph, the number of trays can be increased. In order to link the analysis tools of systems modeled in the bond graph to the mathematical model given to a distillation column, a junction structure of the proposed bond graph is presented. Hence, this junction structure is a way to obtain the state space representation of the modeled column in bond graphs. Likewise, it is well known that distillation columns determine a class of nonlinear systems, so throughout this paper, these systems in a bond graph approach can be analyzed. In order to learn the behavior of the distillation column in the physical domain, simulation results using 20-Sim software are shown. In addition, with the simulation of two case studies consisting of two mixtures with different relative volatilities, the versatility of the column model in a bond graph is presented. In both cases, the increase in the feed flow, the mole fraction of the light component in the feed or the distillate reflux that enriches the concentration of light in the column determine an increase in the mole fraction of light in the distillate and in the bottom reflow. Further, the control design for a distillation column in the physical domain can be extended.
