Abstract

With the clear emission reduction target of China for 2020, the refining industry as a large emission source inevitably plays a significant role. The paper confirmed and assessed three commercially available CO<subscript>2</subscript> separation technologies for refineries, vacuum swing adsorption (VSA), monoethanolamine (MEA) and membrane absorption (MA). The economic results indicate that the capital cost of constructing a CO<subscript>2</subscript> capture unit is 35.996 M¥, 34.418 M¥, 37.502 M¥, respectively. And the corresponding cost of avoided is 379.8 ¥/tCO<subscript>2</subscript>, 249.6 ¥/tCO<subscript>2</subscript> and 376.5 ¥/tCO<subscript>2</subscript>. Sensitivity analyses are also performed examining the effect of CO<subscript>2</subscript> price on economic feasibility, as well as improvements of regeneration energy demand and CO<subscript>2</subscript> capture system on the CO<subscript>2</subscript> avoided cost. The regeneration energy demand impacts the avoided cost significantly, whereas CO<subscript>2</subscript> capture system demonstrates insensitivity. Though the CO<subscript>2</subscript> avoided cost for MEA case is highest, MEA has been commercially the most available processe so far for existing refineries. However, MA will be the most promising alternative to chemical absorption in the future, provided that membrane performance is further improved. In addition, the CO<subscript>2</subscript> avoided cost of VSA is close to that of MEA, but other economic indicators are optimal due to a large amount of H<subscript>2</subscript> recovered. Currently, without any incentive and a major technological break-through, CO<subscript>2</subscript> capture from the source of hydrogen production units at Chinese refineries is the most attractive opportunity.
