中间换热器及热泵对复杂塔处理能力的影响
Effect of intermediate heat-exchanger and heat-pump on capacity of complex distillation columns
摘要
Abstract
To study the capacity expansion of complex distillation column, the effect of adding side condenser, side reboiler and heat pump on the throughput of complex distillation columns was investigated by using the concept of the Fraction of Utilized Area (FUA) proposed by Liu and Jobson and simulator. The FUA curve of the base case which is obtained from the results of simulation can be used to identify the bottleneck of an existing complex distillation column when its throughput is to be increased. According to the shape of the FUA curve, the suitable location and duty of intermediate heat exchanger and/or heat pump for a complex distillation column can be identified. From the shape of the FUA curve of a complex column, it can be known whether the throughput of the column can be increased by adding intermediate heat exchanger and/or heat pump. The study results of the illustrated examples in literature show that the FUA curve is a powerful tool for the analysis of increasing the throughput of complex distillation columns.关键词
