“…These correlations can also be used for modelling heat transfer in single-phase flows in commercially produced PHEs by accounting for pressure losses in ports and distribution zones on commercial plates, as discussed in the paper [39]. These correlations were employed in the mathematical modelling of steam condensation from steam-air mixture in three models of the PHE main corrugated field, with the same corrugation angle to the main flow direction 60 • and different corrugations heights 5.0, 7.5 and 10.0 mm [40]. The mathematical model is presented by the system of ordinary differential equations, which is solved by dividing the PHE channel into small-sized segments along its length.…”

Increasing energy usage efficiency requires enhanced heat energy recuperation between process streams in the industry and civic sector with waste heat utilization. The condensation of different vapours is the process encountered in many industrial applications. Increasing the heat recuperation in this process is possible with efficient heat transfer equipment, among which a Plate Heat Exchanger (PHE) is at the leading position. A number of research works have been conducted in recent years concerning construction development and heat transfer enhancement in conditions of limited pressure drop to increase PHE performance in condensation processes. The results of studies on heat transfer and pressure drop in the two-phase condensing flow inside channels of PHE with different geometries of corrugations are discussed. In many implementations, the total pressure drop allowable for gaseous streams in heat exchangers is relatively small. The structure of two-phase flow in PHE channels of complex geometry is very different than in tubes and flat wall channels. The relative differences in approaches to enhance PHE performance in condensation processes based on its modelling, optimisation and design are analyzed. The directions and prospects for future developments are formulated, and potential savings for the economy and the environmental footprint is presented.

“…It allows having a bigger cross-section area of channels to decrease pressure drop of heat exchanging stream, that is important for gaseous streams and condensing duty applications. The calculations of steam-air condensation in this PHE were made using the mathematical model presented in paper by Kapustenko et al (2020) with heat and mass transfer coefficients determined according to Arsenyeva et al (2014). The results are presented in Table 2 with the purchasing price in € estimated by Equation (Arsenyeva et al 2016):…”

“…PHEs have low fouling tendencies (Crittenden et al 2015). Some PHE types can be used as surface condensers of pure vapour (Arsenyeva et al 2011), of multicomponent vapours mixtures (Tovazhnyansky et al 2004) and of vapour from its mixture with non-condensing gas (Kapustenko et al 2020). This paper is implementing the Process Integration method (Klemeš et al 2018) to find an efficient solution for utilisation of waste sensible and latent heat from exhaust gases with the use of recuperative heat exchangers.…”

In the paper is presented the way of Process Integration application for waste heat utilisation from exhaust gases streams with partial condensation. It is based on the construction of Hot Composite Curve representing the gaseous mixture cooling with accounting for the gas-liquid equilibrium of condensable vapour part. With Cold Composite Curve for streams requiring heating, the Pinch Point is determined. Then the structure of Heat Exchanger Network (HEN) for utilised Heat Integration into the energy system of the factory is developed accounting for the possible splitting of two-phase flow on gas and liquid streams and selection of plate heat exchanger (PHE) types for specific positions in HEN. The method is illustrated by a case study of heat utilisation from exhaust gases after superheated steam tobacco drying and flue gases from natural gas-fired boiler. The heat transfer areas of PHEs in HEN are optimised with the total annualised cost as an objective function. The payback period of the received solution is less than four months with a substantial saving of energy, reduction of greenhouse gases and other harmful emissions of combustion processes.
