Thus, the general function of the vacuum tower is to remove the maximum possible amount of distillate from the charge stock consistent with meeting product specifications on the residuum as well as the …

Jul 14, 2024 · In the oil and gas industry, vacuum distillation towers are used to separate heavy components of crude oil and produce various products. These towers allow refineries to isolate …

Crude Oil Vacuum Towers require reliable, trouble free vacuum systems that operate for months on end, between scheduled shut- downs. The key to a well designed system is the utilization of dependable …

Heavy residue with boiling points exceeding 400 °C (750 °F) are sent to a vacuum tower to allow further recovery without cracking the feed. Three types of vacuum towers are used: dry (no steam), wet …

Heavy vacuum gas oil (HVGO) is a side draw off the tower, and can be used to make asphalt, or can be fed to a Visbreaker or Coker unit for further processing.

Jul 25, 2025 · Atmospheric distillation is indispensable for initial separation, while vacuum distillation is crucial for processing the heavier, complex molecules that atmospheric distillation leaves behind.

The most common application of multi-steam ejectors is in the vacuum distillation column of an oil refinery. A larger fraction of crude oil after the atmospheric distillation is driven into the vacuum …

Incoming gas stream usually enters at the top of the tower and exits at the bottom or the side of the unit. Nozzles and spray patterns may operate in a co–current or counter–current mode depending on …

The bottoms from this tower are then heated and vaporized to enter the flash zone of a “secondary” tower where it is fractionated to meet the conventional overhead and side distillate products.

This condensable steam can cause a vacuum in the quench water tower if no non condensables are added. The tower bottoms is kept at 180°F, if the pressure is allowed to drop into a vacuum, the …
