摘    要:采用参数泵分步结晶工艺,开发了直立弹状流气泡管结晶器,由工业萘提纯制取精萘。实验室研究和放大试验的研究表明,产品纯度大于99%,收率大于92.5%。弹状气泡强化了传热和传质过程,流体的均布是放大过程的关键。

关 键 词:参数泵分步结晶  弹状流    放大

Refining Naphthalene by Parametric Pump Fractional Crystallization
Abstract: crystallizer having a vertical bubble tube with slug flow has been developed on the basis of parametric pumpingThe technology and crystallizer are applied to industrial refining of naphthaleneThe process of heat and mass transfer are strengthened with slug bubble and even disperse of fluid is the key of scale upThe naphthalene purity is over 99% with a yield of over 925%
Keywords:parametric pump fractional crystallization  slug flow  naphthalene  scale up
