Abstract
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.
