Description
Technical field
The invention belongs to crude oil auxiliary agent technical field, and in particular to fail to understand that black suspension thing solid particle is gone in a kind of crude oil
Except auxiliary agent and auxiliary agent filling spray nozzle device.
Background technology
Due to not clear black suspension particle in the light crude oil in part oil field producing region be present, part petrochina oil plant starts
Because crude quality fluctuation is larger, atmospheric unit long-term operation is influenceed, is mainly manifested in：
(1) electro-desalting and storage are caused between crude oil and water containing the emulsification non-oil thing of shape, the milk density in crude oil
Transport that tank field removing is especially difficult, and especially it is higher to easily cause electric desalting apparatus electric current for the milk, electro-desalting tripping operation frequently occurs,
Have a strong impact on electro-desalting long-term operation.
(2) often there is blackening phenomena in electric desalting apparatus dehydration, and the processing to oil-polluted water causes extreme difficulties, and to complete
Factory's sewage disposal system causes to have a strong impact on the exceeded potential risk of sewage discharge be present.
(3) black suspension thing is carried in crude oil, causes Atmospheric Tower sour water blackening, atmospheric unit normal pressure tower tray floor goes out
Often there is unusual fluctuations, device fortune in existing jelly accumulated plugging tower tray, tower tray fouling, sewage stripping and sulfur recovery facility
