Discussion on over-steam oil in distillation columns
Thread Content
1. Do the distillation towers, fractionation towers, and rectification towers in various companies’ facilities all use vaporized oil? Feel free to discuss how vaporized oil can be used to guide adjustments in production operations; you go first and I’ll follow. 2. Has any unit carried out modifications to extract the vaporized fuel, and what were the results? Everyone is welcome to share their production experience.
Excess vaporized oil refers to the difference between the amount of raw material that vaporizes and the amount of product extracted from above the feed section; this is known as excess vaporized oil. It can also be described as the flow rate of liquid returning below the lowest side-stream extraction tray above the feed section. Reducing the amount of over-vaporized oil helps to lower the energy consumption of the plant. For atmospheric and vacuum distillation units, a common approach is to control the feed temperature ； Second, the regular four-line extractive tray was replaced with a full-extractive tray
