DISTILLATION: Optimizing Outcomes Through Better Design and Operation


SKU: CE133 Category:


Distillation is one of the most fundamental unit operations used in chemical process plants. Efforts to properly design, specify and operate distillation columns are critical to optimal operation, as are the latest strategies for maintaining, troubleshooting and revamping them when necessary. And modern revamps typically include efforts to troubleshoot and upgrade ancillary equipment, such as reboilers, condensers, pumps, valves, heat exchangers and instrumentation.

The engineering articles contained in this Chemical Engineering Guidebook share proven strategies and best practices aimed as improving distillation. Several articles focus on the use of process simulation to help engineers evaluate and improve the performance of proposed and existing distillation columns.

Delivered in a PDF format, this guidebook is 179 pages.
