Desalting of oils with a density greater than 1
Thread Content
I’m sorry; I’m a new trainee. For oil products with a density greater than 1, is it okay to allow water to be discharged from the upper part of the desalination tank?
What kind of oil is the one you refer to as having a density greater than 1? If it is crude oil, then it shouldn’t be called a petroleum product. If the density of the crude oil is greater than 1, its viscosity is very high; to achieve good flow and mixing properties, higher temperature conditions are required. For the desalination of this crude oil, it is preferable to recycle part of the normal paraffinic fraction and mix it with the crude oil, or to blend it with other crude oils of lower density before carrying out the desalination process.
