Mini-Refinery Vacuum Unit: Functional Analysis and Improvement of Vacuum Overhead System
The purpose of this study was to analyze the functioning of the vacuum distillation unit of a mini-refinery and to develop recommendations for improving the vacuum overhead system with the aim to reduce the cost of creating and maintaining a vacuum in the fuel oil separation column. A calculation mo...
