Adjusting principle of temperature of crude oil electric desalting

The temperature of electric desalting is an important control parameter of electric desalting operation, which seriously affects the smooth operation of electric desalting equipment and the desalting effect of crude oil, so it is necessary to strengthen the control in daily operation.

If the feed temperature rises quickly to form a "surge", then the density of hot oil entering the lower part of the container becomes smaller, which is easy to cause the hot oil device to return the heavy cold oil on the upper part of the container, forming a "hot agitation", which will affect the normal operation in serious cases.

Therefore, the temperature adjustment of electric desalting should be slow and stable in order to facilitate the stable production of desalting.
