Problems solved by technology

However, when the operating temperature of electric desalination and dehydration and the properties of crude oil do not change much, the density difference between crude oil and water and the viscosity of crude oil change very little. Therefore, efforts can only be made to reduce the rising speed of crude oil in the electric field
