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。
crystallizer having a vertical bubble tube with slug flow has been developed on the basis of parametric pumpingThe technology and crystallizer are applied to industrial refining of naphthaleneThe process of heat and mass transfer are strengthened with slug bubble and even disperse of fluid is the key of scaleupThe naphthalene purity is over 99% with a yield of over 925%
