selecting most appropriate co2 capturing technology using analytical hierarchy process

Exponential growth of greenhouse gas emission from industrial companies leads to the global warming and climate change effects# among the greenhouse gases, co2 is more responsible and has a key role# thus, removing that from flue-gases considered as a global issue# co2 capturing methods should be regarded as a practical solution to meet global standards and prerequirement# capturing process has three main types including pre-combustion, post-combustion and oxy-combustion# the main focus is to prevent the emissions from releasing to the atmosphere just after the combustion# therefore, it is better that capturing process applied in post-combustion technologies# this could yield more practical and effective outcomes# to achieve best choice and solution, multi-criteria decision-making concept using analytical hierarchy process (ahp) applied as a useful technique# in this work, five most common technologies of co2 capturing evaluated# all important criteria considered to give a perfect perspective of comparison of technologies# eventually, low-cost and absorption have the highest rank and priority as a criterion and technology respectively#
