文章摘要
This study aims at determining the optimal CO2
separation technology for Chinese refineries, based on
current available technologies, by the method of comprehensive
evaluation. Firstly, according to the characteristics
of flue gas from Chinese refineries, three feasible CO2
separation technologies are selected. These are pressure
swing adsorption (PSA), chemical absorption (CA), and
membrane absorption (MA). Secondly, an economic
assessment of these three techniques is carried out in
accordance with cash flow analysis. The results show that
these three techniques all have economic feasibility and the
PSA technique is the best. Finally, to further optimize the
three techniques, a two-level fuzzy comprehensive evaluation
model is established, including economic, technological,
and environmental factors. Considering all the
factors, PSA is optimal for Chinese refineries, followed by
CA and MA. Therefore, to reduce Chinese refineries carbon
emission, it is suggested that CO2 should be captured
from off-gases using PSA.
