摘要
针对气体分馏装置丙烯精馏塔规模大幅提高的趋势 ,从回流比、能耗、水力学性能及投资等方面综合分析讨论了塔板数的优化。指出丙烯精馏塔塔板数的优化具有明显的技术经济效果。在目前的技术经济条件下 ,对于 0 .6Mt/a的气体分馏装置丙烯精馏塔 ,推荐采用 2
Optimization for tray's number of propylene rectification tower was comprehensively analyzed from reflux ratio,energy consumption,hydrodynamics and investment.It was pointed out that the optimization for trays' number has evident techno economic effect.To adapt present techno economic conditions,the theoretical trays' number of 215 were recommended for the propylene rectification tower of the 600000 tpy gas fractionation unit.
