摘要

A hydraulic performance indicator, fractional utilization of area (FUA) can be used to identify the bottleneck of an existing distillation column when the throughput is to be increased. This analysis tool allows identification of modifications to increase the throughput to an existing distillation column. The work focuses on design options that increase the effectiveness with which the existing shell and internals are utilized, rather than simply replacing the internals. Some effective modifications can be quantified directly (i.e. without using trial and error), while qualitative guidance for others can be obtained. The design tool allows relatively inexpensive design options to be identified and evaluated, reducing simulation and design effort and providing improved solutions, compared to conventional techniques.
