8 Challenges Facing Bio-oxycombustion Technology
The implementation of bio-oxycombustion technology is a cost-effective means of
BCCU, which could significantly reduce emissions from various industrial manufacturing sectors. R&D needs regarding fundamentals and performance of the
oxycombustion system, scale-up of photobioreactors, and the integration and
optimization of processes are identified in Table 5, for that the integrated
bio-oxycombustion system can be fully scalable in the future.
9 Final Considerations
The growing development of oxycombustion systems has proven to be a viable
strategy to mitigate CO 2 and increase the thermal efficiency of industrial processes.
The integration of this technology with microalgae-based processes is considered an
important engineering approach to promote sustainable development. Therefore, the
full use of the photobioreactors exhaust gases could provide overall improvements
in the thermal performance of integrated bio-oxycombustion systems. However, the
CO 2 industrial biotransformation into O 2 and VOCs is very limited due to lack of an
ideal photobioreactor design. Conversely, considering that combustion systems
have extensive infrastructure, it would be necessary to design a photobioreactor that
would operate at large volumes for the production of these substances in a mature
industrial process. In this sense, for that bio-oxycombustion technology to present
viability, efficiency, and productivity, operational problems must be solved in order
to meet industrial demand for photobioreactors with applicability in full scale at
field conditions.
