The invention relates to injecting steam into crude oil in two separate desalting steps to remove salt by transferring the salt into the condensed water from the steam and gravity separating the water from the crude oil. Steam transfers salt from crude oil via a different transfer mechanism. In the invention, salt is also removed via an intermediate step of adding water with harshly mixing the added water with the crude oil between the gravity separation of the first steam desalting step and before steam is added in the second step.

The invention relates to removing salt from crude oil via two steps of adding water with harsh mixing of the added water with the crude oil and gravity separating the salty water between steps where the process additionally includes a step of injecting steam into the crude oil after the first of the two water adding and harsh mixing desalting steps, but upstream of the gravity separation of the first step. The steam separates salt by transferring the salt into the condensed water from the steam.

The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.

A grease recovery device 1 having a container 2 with walls 3 and a lid. The grease recovery device 1 further having a drum 5 for lifting fats, oils, grease and/or solids (FOGS) rotatably mounted on the container 2 and a wiper blade assembly 6. The wiper blade assembly 6 being in operable engagement with the drum 5. A wall 3 of the container 2 has an arrangement 7 for releasably housing the wiper blade assembly 6 in an operational position in the container 2. The releasable housing arrangement 7 comprising an opening 8 for slidably receiving the wiper blade assembly 6 and a support arrangement 9 disposed at or about the opening 8 so as to allow the wiper blade assembly 6 to be inserted into and removed from the grease recovery device 1 without removing the lid or opening any cover of the container 2.

The invention relates to injecting steam into crude oil via a hydrocyclone to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt from crude oil via a different transfer mechanism and the water is separated from the crude oil leaving desalted crude oil for refining.
