Let’s discuss what good methods exist for the pretreatment of high-sulfur crude oil in atmospheric and vacuum distillation units How is heavy metal removed? How to desulfurize?
It mainly relies on dehydration in the tank area, pays attention to the design and selection of electrodesalination systems, and optimizes the operation of these systems.
There are no good methods for desulfurization; electrodesalination devices can only remove inorganic sulfur and have little effect on organic sulfur. As for removing heavy metals, it depends on which metals need to be removed There are specialized decalcifiers (desalting agents)
The key is still dehydration! Everything is in the water!
The most effective method at present is the H addition technique, but its drawback is the high cost.
Previously, experts in China also suggested the use of crude oil hydrogenation treatment, but it has not been put into practice to date. In fact, crude oil hydrogenation treatment has a significant impact on the corrosion of subsequent processing equipment as well as on the specifications of the materials used. Nowadays, such treatment is only applied when it is necessary, and the costs involved are quite high!
I think it’s mainly one bet with four outcomes.
