| 제목 | Phase Equilibrium Studies of Three-component CO2-N2-Water Involving Gas Hydrate |
| 초록 | Phase equilibria of CO2+N2+water provides an important information for design of carbon capture and storage. Reliable experimental data for 3 phase(liquid water + hydrate + vapor) equilibrium for water,CO2 andN2 had been reported using indirect method*1. In this study, 4 phase equilibrium(liquid water + liquidCO2 + hydrate + vapor) forCO2+N2+water and 2 phase equilibrium(liquid CO2 + hydrate) ofCO2 rich phase (mwater ＜ 1.0-2)were measured by observing the phase boundary of predetermined composition system containing gas hydrate. 4 phase equilibrium lines in PTspacewere measured for given compositions. 2 phase equilibrium ofCO2 rich phase were measured for given pressures (60, 100, 150 bar). The experimental data were compared with calculated result by CSMGem *2. [1]Kim, Y.S., B. D. Lim, et al.
