To intensify heat transfer in reboiler, spinning disc technology is recommended.
It is currently well established that Lagrangian chaos intensifies heat transfer significantly [J. Fluid Mech. 209 (1989) 335].
In such extreme conditions, the generation of spatial chaos by geometrical perturbation in the heat exchanger is a relevant way to intensify heat transfer.
It is supplemented with the search of economically viable options of desorption column parameters by computer modelling and the use of compact PHEs (plate heat exchangers) with intensified heat transfer.
In the retrofitted HENs, several conventional intensified heat transfer techniques are available, including tube-side intensification (twisted-tape inserts, coiled-wire inserts and internal fins), and shell-side intensification (external fins and helical baffles).
In this paper, an optimisation method has been developed for dealing with the retrofit of large scale HENs in which the location of intensified heat transfer within the network and its degree of intensification are systematically identified, given the objective function and design constraints, including topological limitation in the existing heat recovery systems.
Intensified heat transfer (IHT) techniques have recently been used for retrofit in the process industry, leading to significant energy saving in heat exchanger network (HEN) by facilitating heat transfer intensification without network topology modification.
They cracked like coriander, releasing a billowing aroma, and then a slowly intensifying heat, like pepper.
Two-phase monolith-type reactors allow intensified heat and mass transfer rates, but often suffer from fluid maldistribution and undesired flow regimes in channels.
The use of rotation to intensify heat and mass transfer has become one of the most spectacular tools in the armory of the plant engineer in several unit operations, ranging from reactors to separators.
