| 摘 要： | 在直径10厘米、直管段高3.21米的气升环路中,以十一种物料体系研究了不同气速和循环液速下的气含率.结果表明,对低粘液体可以用公式ε=0.647[u_G/u_G+u_L)]~(0.68)u_G~(0.34)来关联数据.文中还列出了气升环路系统中流体流动的动量方程,与上式合解可以计算气升环路中的气含率和循环液速,与实验值对比,其平均偏差分别为±3.2%和±4.6%.

| Abstract: | Experiments were conducted in a pilot-scale gas-lift loop reactor with an upleg measuring 10 cm in diameter and 3.21m in height. The gas holdup at different gas injection rates and liquid recirculating velocities foreleven different liquid gas systems were measured, and the data correlated.The results yielded the correlation ε =0.647 for low-viscosity liquid systems.With the above correlation and a simplified momentum equation for fluid flow in the loop, the gas holdup and liquid recirculating velocity for a given gas injection rate in a given loop may be predicted by calculation, with an average deviation of ±3.2% and ±4.6% for ε and uL respectively. |
