| Summary: | One of the new approaches for capturing carbon dioxide from treated flue gas (post-combustion capture)
and fuel gas (pre-combustion capture) is based on gas hydrate crystallization. The presence of small amount
of tetrahydrofuran (THF) substantially reduces the hydrate formation pressure from a flue (CO2/N2) gas
mixture and offers the possibility to capture CO2 at medium pressures [1]. A conceptual flow sheet for a
medium pressure hydrate process for pre-combustion capture from a fuel gas (CO2/H2) was also developed
and presented. In order to test the hydrate-based separation processes for pre and post combustion capture
of CO2 at a larger scale a new apparatus that can operate with different gas/water contact modes is set up
and presented. |
