O₂, N₂, CO, CO₂ capture technologies in the post-combustion operation of the waste stream (A review)

Malek Hassanpour

The presence of post-combustion main gaseous products dissipated into the environment participated in emerging serious damages in the atmosphere. The combustion operation as one of the prominent technologies posed in the disposal of waste stream emits huge quantities of valuable gaseous products as well as its emission of various industrial and non-industrial resources that can be an appropriate feedstock for many industrial units. The objective of the present review conducted towards technologies that came into view in handling and separating gaseous products of O₂, N₂, CO, CO₂ in the post-combustion operation. Therefore, the concepts and implications picked up from scientific references to demystify the overwhelming technologies that emerged in this regard. The findings attract the interests of the researchers by defining the framework of a matrix of criteria and alternatives for the experts' opinion and making the decision for the best alternative possible. Also, the important industrial plants implemented in Iran were explained with the best technologies selected for the gas capturing operation. According to available technologies, it was found the sorbents and molecular sieves as best choices that have been detected by the Iranian assessment team in Environmental Impact Assessment (EIA) plan. The conclusion of the review can be allocated to offering further options in alternative energies based on the new technologies asserted and environmental challenges raised.
