Abstract
|
Increasing
concentrations of greenhouse gases (GHGs) such as CO2 in the atmosphere is a
global warming. Human activities are a major cause of increased CO2
concentration in atmosphere, as in recent decade, two-third of greenhouse
effect was caused by human activities. Carbon capture and storage (CCS) is a
major strategy that can be used to reduce GHGs emission.
There
are three methods for CCS: pre-combustion capture, oxy-fuel process, and
post-combustion capture. Among them, post-combustion capture is the most
important one because it offers flexibility and it can be easily added to the
operational units. Various technologies are used for CO2 capture, some of
them include: absorption, adsorption, cryogenic distillation, and membrane
separation. In this paper, various technologies for post-combustion are
compared and the best condition for using each technology is identified.
