摘要:
Hydrate-based CO2 capture (HBCC) has received increasing attention, due to such advantages as the mild operating pressure and temperature, the ease of regeneration and its unique separation mechanism. This review paper is focused on the chemical additives and the mechanical methods that have been investigated to improve the CO2 separation efficiency and energy consumption through HBCC technology. Detailed comparisons of the effects of various chemical additives and mechanical methods on gas consumption, operating conditions, hydrate induction time and CO2 recovery are critically reviewed. The limitations and challenges of HBCC, in comparison with the conventional methods for CO2 capture also are discussed. (C) 2015 Elsevier B.V. All rights reserved.
