Figure 5-3 shows an alternate configuration known as a “bucket and weir” design. This design eliminates the need for a liquid interface controller. Both the…
In many refineries most of theC4’s and lighter are removed from the atmospheric column overhead distillate in the first column of the light end unit.…
Liquid carryover and gas blowby are two common operating problems. Liquid carryover occurs when free liquid escapes with the gas phase and can indicate high…
All ASME Code vessels are inspected by an approved Code inspector. The manufacturer will supply Code papers signed by the inspector. The nameplate on the…
This fraction is usually the first side stream of a conventional atmospheric distillation unit. It may be cut to meet a burning oil specification or…
This is the bottom product from the atmospheric distillation of the crude oil. Most crude oils are distilled in the atmospheric crude oil tower to…
A weir system separator is a device that separates a mixture of oil, water, and gas into its individual components. It is commonly used in…
Control valves are used throughout the process to control pressure, level, temperature, or flow. It is beyond the scope of this text to discussthe differences…
To maintain pressure on a separator, a liquid seal must be effected in the lower portion of the vessel. This liquid seal prevents loss of…
It can be shown mathematically that an efficient design must have a high gas induction rate, a small diameter induced gas bubble, and relatively large…
