Abstract

This article deals with experimental research of the direct-contact condensation in column with structured packing. Lots of experiments have been performed in a column of 257 mm inner diameter with Topic 125 Y structured packing using hydrocarbon mixtures. The influences of the vapor and liquid flow rate as well as liquid temperature at vacuum pressure have been investigated. A new empirical correlation was developed to predict the heat transfer coefficient for structured packings, which can be applied to both design and simulation of distillation columns in petroleum refinery.
