| 제목 | A study on selective separation of CO2 using gas hydrate formation |
| 초록 | As a method for selective separation of CO2 from the flue gas which has low CO2 composition, this study was performed on how to use gas hydrate formation. In particular, using as an additive TBAB (Tetra-n-butyl ammonium bromide), the degree of relaxation of thermodynamic phase equilibrium and the selection of the gas entrapment was investigated. Then, we presented a multi-stage process on the basis of the results of these study to obtain high purity CO2. We confirmed the equilibrium conditions of mild temperature conditions of more than 284K of 10,20,30,40,50 bar pressure. And we were able to know that the composition of CO2 increased compared to composition of N2 entrapped in TBAB semi-clathrate, the lower pressure at analysis of gas composition at each pressure. In addition, we tried to check the presence of structure of the cage 51263 which is conformed at TBAB semi-clathrate through Raman spectroscopy, the flowsheeting has designated a process that takes into account the aspects of economic efficiency. |
