本研究展示了四款基于 990 微型气相色谱平台的 NGA 分析仪。每种分析仪的配置取决于其目标天然气的组成。NGA分析仪 A 能够在两分钟内完成空气、甲烷、二氧化碳和 C2–C6 烃类的分析。重质化合物(高达 C9)的分析可在约 5 分钟内完成。为了快速分析含有重烃(高达 C12)的天然气,采用配备三通道的扩展型 NGA 分析仪 A。NGA 分析仪 B 能够分析的样品与 NGA 分析仪 A 所能分析的样品组成类似,此外它还能够分析 H2S。
In the present work the effect of temperature on the hydrodynamic behavior of fluidized beds is experimentally studied with modern non-invasive experimental techniques. In particular, the development of a high temperature endoscopic Particle Image Velocimetry (PIV) is presented. An experimental set up has been designed and constructed that allows the study of hydrodynamics up to temperatures of 1000 oC, typical temperatures encountered in chemical looping gasification processes. First the endoscopic PIV results have been validated at low temperatures with a cold flow setup. Subsequently the application of the new technique to high temperature fluidized beds is presented and the obtained results discussed.
