The simulation results can be used to understand the transport variation and the inundation distribution induced by the storm surge on the interested area during typhoon invades. The case in this study is Typhoon SEPAT, which passed through central Taiwan in 2007. The transport characteristics through Taiwan Strait under the influence of Typhoon SEPAT were discussed by comparing the field observations and numerical simulations during the typhoon period. The results indicate that the surge height of Typhoon SEPAT did not respond to the peak of wind waves accompanied with 15 hrs time lag. According to the influence of dynamical forces on the storm surge in Taiwan Strait, the onshore wind is the dominant role of coastal inundation during this typhoon event in Taiwan Strait. By observing the inundation map through the typhoon period, the coasts of Yulin County are verified to be the most serious affected area in the vicinity of Taiwan Strait.展开更多

Separation and purification of structurally similar paraffin/olefin/alkyne mixtures are important for the production of highpurity or even polymer-grade light hydrocarbons. However, traditional methods such as cryogenic distillation and solvent absorption are energy-intensive and environmentally unfriendly processes. Ionic liquids(ILs) as a new alternative to organic solvents have been proposed as promising green media for light hydrocarbon separation due to their unique tunable structures and physicochemical properties resulting from the variations of the cations and anions such as low volatility, high thermal stability, large liquidus range, good miscibility with light hydrocarbons, excellent molecular recognition ability and adjustable hydrophylicity/hydrophobicity. In this review, the recent progresses on the light hydrocarbon separation using ILs are summarized, and some parameters of ILs that influence the separation performance are discussed.展开更多
