First of many major processes in transforming crude oil into usable products at an oil refinery
Thermal separation of crude oil into products (naphtha, kerosene, diesel, gas oil, residue) based on different boiling point volatilities
5%(Heavy)-95%(Light) = value
Large gap values yield sharper cuts but also cost more to maintain
Gas oil stripper
Stripping steam is limited, so light weight vapors are used to strip intermediate components.
Compressor work and vapor flow-rate is not significant enough to negatively affect economics.
For all types of crude, increased yield of gas oil and diesel, reduced residue.
No change in heating utility, although increase in cooling utility.
With intermediates removed, the lighter components create a “vacuum” as they rise up the column, pulling more intermediates from the residue cut.
components removed in preflash.
Removes intermediates before they are fed into the column to increase carrier effect.
Flash Drum 2
Flash Drum 1
Reduction in residue decreases with increase in crude weight.
Reduction of furnace utility and cooling utility.
Gas Oil Stripper
Higher stripping pressure.
Injected vapors include light weight vapors and lightends in addition to intermediate weight vapors.
Higher stripping pressure reduces effectiveness of carrier effect.
Highest increases in gas oil production across all crudes.
Increases diesel production in heavier crudes.
Slightly increases heating utility.
Adversely affects diesel production.
The two designs offset each other.
Unprofitable for intermediate crude.
Second highest increase in diesel and gas oil production.
Highest reduction in heating utility.
