Can anyone advise whether it is worth to install desalter for crude with salt content ~10-20 PTB. Or it is better just to inject anticorrosion agents?
Additionally, any experience with desalting of heavy crudes (10-15 API, e.g. Venezela crudes)? Can standard electrostatic desalter handle such heavy crude (with respect to high viscosity and low difference between crude/water density thus poor separation/efficiency)?
Many thanks!
