摘　　要：塔板效率包括:点效率、莫夫里效率和全塔效率,它们的值主要受流体多相流动时的动力学体系特性的影响;点效率可由双膜理论推出,莫夫里效率和全塔效率存在一定的内在关系。Plate efficiency includes Local, Murphree and overall efficiencies in a distillation column, which are mainly affected by kinetic system performance of muhiphase fluid flow. Local efficiency can be reasoned from Two--Film Theory, and a relation between overall and Murphree efficiencies exist.

关 键 词：板式精馏塔 点效率 莫夫里效率 全塔效率
