GOALI: Transport Phenomena of High Pressure Gas - Liquid - Solid Fluidization

CTS-9906591L.-S.Fan，俄亥俄州立大学将在高压(高达21兆帕)和高温(高达200摄氏度)下研究三相流态化系统中的微观现象。流态化和可视化实验室设施是在之前NSF赞助的项目中开发的。初始气泡的形成、喷射和破碎将被可视化和机械模拟。颗粒惯性、气泡不稳定性、热传递、压力和温度的影响将包含在微观模型中。对高压浆体鼓泡塔内的混合物流动进行了宏观模拟，包括颗粒悬浮的临界气速和气含率。将尝试推广气相、液体相和固相的各种性质的结果。这是俄亥俄州立大学与壳牌公司、德士古石油公司、埃克森美孚研发公司和碳氢化合物研究公司四家公司合作实施的Goali项目。工业合作伙伴将与人员一起参与研究，设计部分实验设施，并从大规模实验中获得反馈。如果成功，该项目将为高压/高温三相流态化系统提供基础研究数据，与石化行业直接相关，特别是在甲醇合成、苯加氢和树脂加氢处理方面。

CTS-9906591L.-S. Fan, Ohio State UniversityMicroscopic phenomena in three-phase fluidization systems will be investigated at high pressures (up to 21 MPa) and high temperatures (up to 200 degrees C). The fluidization and visualization laboratory facility was developed in the previous NSF sponsored project. Initial bubble formation, jetting, and breakup will be visualized and mechanistically modeled. The effects of particle inertia, bubble instability, heat transfer, pressure and temperature will be included in a microscopic model. Macroscopic modeling of mixture flow in high-pressure slurry bubble columns will be performed including critical gas velocity for particle suspension and gas holdup. An attempt will be made to generalize the results for various properties of the gas, liquid and solid phases. This is GOALI project performed in collaboration between the Ohio State University and a network of four companies: Shell, Texaco Oil, Exxon R&D, and Hydrocarbon Research Inc. The industrial partners will contribute to the research with personnel, design of parts of the experimental facility and feedback from large-scale experiments. If successful, the project will provide fundamental research data for high pressure/high temperature three-phase fluidization systems, with immediate relevance to petrochemical industry and specifically on methanol synthesis, benzene hydrogenation and resin hydrotreating.
