项目摘要

The environmental problems on global warning are now very severe in the world. The typical global warning gas is carbon dioxide. In the world, the average amount of carbon dioxide produced per one person is approximately 10 kg per day, to keep the comfortable modern life. The treatment of carbon dioxide is important in the world.Aqueous solutions containing 2-aminoethanol or cyclohexylamine show excellent ability for the absorption of carbon dioxide of the typical global warming gas. The solutions can be recovered after boiling the solutions and further condensing the vapor except carbon dioxide in the process. In the design and operation of the recovery process, the vapor-liquid equilibria are required for the solutions concerned. In the present study, vapor-liquid equilibrium relations of the aqueous solutions containing 2-aminoethanol or cyclohexylamine are measured at atmospheric pressure To immobilize recovered carbon dioxide under the ocean, physical properties of methane/ethane hydrates is important to develop environmental technologies.Phase equilibria and saturated densities for ethane + 1-butanol system at high pressures were measures using a static-circulation apparatus at 313.15 K. The experimental apparatus equipped with three Anton Paar DMA 512S vibrating tube density meters was previously developed for measuring vapor-liquid-liquid equilibrium (VLLE) at high pressures. Co-existing phase composition and saturated density of each phase can be measured by means of the apparatus with a maximum temperature and pressure of 400 K and 20 Mpa, respectively. The present experimental results include vapor-liquid equilibria (VLE), liquid-liquid equilibria (LLE), and VLLE. The equilibrium composition and density of each phase were determined by gas chromatography and density measurements, respectively. The experimental data were correlated with various equations of state.

现在，全球警告的环境问题在世界上非常严重。典型的全球警告气是二氧化碳。在世界上，每人生产的二氧化碳的平均量为每天约10公斤，以保持舒适的现代生活。二氧化碳的处理在世界上很重要。含有2-氨基乙醇或环己基胺的水溶液表现出极好的能力，可以吸收典型的全球变暖气体的二氧化碳。在煮沸溶液后可以回收溶液，并在此过程中进一步冷凝蒸气。在恢复过程的设计和操作中，有关解决方案需要蒸气液平液。在本研究中，在大气压力下测量含有2-氨基乙醇或环己基的水溶液的蒸气 - 液平衡关系，以使甲烷/乙烷的物理性能固定在海洋下的二氧化碳，甲烷/乙烷的物理性能，甲烷/乙烷水合物对于开发环境技术的含量均高于乙烷均衡。 313.15K处的静态循环装置。先前开发了配备了三个Anton Paar DMA 512S振动管密度仪表的实验设备，用于测量高压下的蒸气液液体平衡（VLLE）。可以通过设备的最高温度和压力分别为400 K和20 MPa来测量每个相的共存相位组成和饱和密度。目前的实验结果包括蒸气液平衡（VLE），液体液位平衡（LLE）和VLLE。分别通过气相色谱和密度测量确定每个相的平衡组成和密度。实验数据与各个状态方程相关。
