Oxygen-enhanced combustion (OEC), alternative energy, oxygenseparation processes
This paper presents a thermodynamic analysis of the process known
as oxygen-enhanced combustion (OEC). In order to have a better
evaluation of this process, a simple system was modeled, composed
only of the main components needed to simulate an OEC process.
The concentrated oxidant stream required for the OEC process is
provided by a polymeric membrane set. Results show an increase
of the energetic eﬃciency, from 22% to 58%, compared to regular
atmospheric combustion. The exergetic eﬃciency follows the same
trend, from 18% to 48.5%. A reduction of more than 60% of speciﬁc
pollutants emissions is shown. The assessed technique points out
to be energetically more attractive than cryogenics for small plants,
the size limit depending on operating conditions.
