“…The authors reported that the flexibility of the process was increased as well as energy recovery; the primary energy consumption was reduced by 25 %. There are some applications of MP for simultaneous design of HEN and distillation columns with improved heat integration [125]. Later the authors proposed a method for the synthesis of an economically optimal HEN [126].…”

Due to the rapid growth in the world population, there has been an increase in energy consumption globally. The problem of efficient energy use becomes more relevant and stimulates research and development of new energy and resource-saving technologies. This task is becoming more complicated when the other factors are accounted for, resulting in multiple-factor trade-offs, such as the water-energy-food nexus. This paper highlights the main points for the development of Process Integration in the Commonwealth of Independent States (CIS) countries. It shows the main achievements in the field to date and demonstrates the scientific schools that are working on these problems. A comprehensive review of modern approaches and methods, which are now being developed or have been recently developed, was done. It shows a research gap in Process Integration in CIS and other leading countries. It demonstrates the significant research potential as well as practical applications. The main challenges in process systems engineering and for the sustainable development of industrial energy systems are also discussed. Industry digital transformation, energy transition, circular economy, and stronger energy and water integration are pointed out as priorities in analysis, design, and retrofit of society in the future. A state-of-the-art review in the area of integration of continuous and batch processes, mass integration technologies, and process intensification is presented to show the variety of existing approaches. The necessity of Process Integration development in the CIS is shown to be a necessary condition for building a more sustainable society and a resource-efficient economy.

“…An important factor influencing the synthesis of the system is the heat exchange kinetics—the dependence of the heat flow on the temperatures of the contacting flows. Finally, restrictions can be imposed on the temperatures of incoming and outgoing flows because the heat exchange system is integrated with the technological process 1 . Thus, during the multi‐column distillation, the technological requirements dictate certain temperatures and heat capacities of the flows, and the heat exchange system may include the heat exchange column units (a cube and a reflux condenser).…”

The paper considers the synthesis of heat exchange systems according to the criteria of minimum irreversibility and minimum contact surface. It considers the cases of variable heat capacity of streams, changes in their phase state, and different hydrodynamics. The work takes into account the temperature limits for all or part of the flows at the inlet and outlet of the heat exchange system. To synthesize, it is required to choose the contact structure, free flow parameters, distribution of contact surfaces, and thermal loads between double-flow heat exchangers.

“…Many technology processes in the chemical, food, and metallurgy industries are characterized by significant flows of released and consumed energy that can be used both in the process itself for the heating or cooling of the incoming flows and for other purposes. Heat-exchange systems integrated with the technology process [1][2][3][4], etc., are used for the utilization of this energy.…”

“…Technical, economic, and process criteria are used as the efficiency index. In the first case, the criterion takes into account the cost of creation and operation of the heat-exchange system [3,4], and in the second, parameters such as energy losses due to the irreversibility of heat exchange under the limitation for the total heat transfer coefficient [5,6]. The losses of operable energy are also used in the exergy assessment of thermodynamic systems (see [7,8], etc.…”

An algorithm of the synthesis of systems integrated with a technology process is proposed when the temperatures and heat capacities of all or some flows are fixed, and it is necessary to construct a heat recovery system with the minimum total heat transfer coefficient (contact area). The algorithm is based on the construction of a two-flow calculated heat exchanger that is thermodynamically equivalent to a multiflow system. It is shown that the proposed algorithm is true for any form of heat exchange kinetics, which can be presented as a product of the heat transfer coefficient by a factor that depends on the temperature of the contacting flows.
