GOALI: Transport Phenomena of High Temperature/High Pressure Gas-Liquid-Solid Fluidized Beds

CTS-9528380将进行压力高达22 MPa，温度高达200℃的气液固流化流动可视化和传热研究。研究了改变三相流化床压力和温度的影响。建立了一个实验装置，用于PIV可视化和热输运实验。气泡运动、聚并和破裂过程将根据测量结果进行分析。流化系统的状态转变、初始流化、相滞留和床层膨胀/收缩现象将被确定。用微箔流传感器测量三相流中的局部传热特性。该项目将与四个工业单位（壳牌开发公司、阿莫科石油公司、碳氢化合物研究公司和埃克森美孚研发公司）合作，根据与工业学术联络的资助机会（GOALI）计划进行。该项目将带来三相流的新知识，并将其应用于与石油工业相关的流化床反应器的设计和操作。＊＊＊

ABSTRACT CTS-9528380 Flow visualization and heat transfer studies of gas-liquid-solid fluidization at pressure up to 22 MPa and temperature up to 200( C will be conducted. The effect of changing the pressure and temperature in three-phase fluidized beds will be investigated. An experimental apparatus has been built to enable PIV visualization and thermal transport experiments. Bubble motion, coalescence and break-up processes will be analyzed based on the measurements. Regime transitions, incipient fluidization, phase holdups and bed expansion/contraction phenomena will be determined for the fluidization system. The local heat transfer characteristics in three-phase flow will be measured using a microfoil heal flow sensor. This project is proposed to be conducted in collaboration with four industrial units (Shell Development Co., Amoco Oil Co., Hydrocarbon Research Inc., and Exxon R&D Co.), under the Grant Opportunities for Academic Liaison with Industry (GOALI) initiative. The project will lead to new knowledge for three-phase flow, with application to design and operation of hydrocarbon processing in fluidized bed reactors of relevance in oil industry. ***
