Like wastewater or sulfur recovery, the desalter is not a glamour unit, but it is critical to refinery operations. Salts in crude oil feedstocks can cause severe problems, including corrosion in the fractionator, fouling of heat exchangers, and poisoning of catalyst. Operating the desalter smoothly is vital and difficult, therefore requiring daily monitoring for optimal performance.
