Description

Technical Field

[0001] The utility model relates to the technical field of crude oil dehydration, in particular to a crude oil dehydration device for oil development. Background Art

[0002] Crude oil usually refers to unprocessed petroleum. It is a dark brown viscous oily liquid with green fluorescence and a special smell. It is a mixture of various liquid hydrocarbons such as alkanes, cycloalkanes, aromatic hydrocarbons and olefins. After crude oil is mined from the seabed, it contains a certain amount of water. Therefore, a dehydration device is needed to dehydrate it by taking advantage of the different boiling points of water and crude oil.

[0003] Most of the existing crude oil dehydration processes are carried out in a reactor. However, after the crude oil to be dehydrated in the reactor is stirred, it needs to be left to stand for easier stratification of water and oil in the crude oil. After the crude oil is stirred, the stirring rod in the reactor is often placed inside the crude oil. When the crude oil is drained after dehydration, a certain amount of crude oil will adhere to the stirring rod inside the crude oil, which is not only inconvenient to clean the stirring rod, but also causes waste of crude oil.

[0004] Therefore, we have made improvements to this and proposed a crude oil dehydration device for oil development. Utility Model Content
