The first line of defense for successful refinery crude unit corrosion and fouling control is optimal operation of the desalter. Today’s opportunity crudes, including synthetic crudes, diluted bitumen, diluted crude oils, and shale oils, vary greatly in terms of quality and the processing challenges they represent. Additionally, crudes and their blends can be incompatible, precipitating asphaltenes and high molecular weight aliphatic compounds. This precipitation can increase the stability of emulsions and contribute to downstream fouling. Fluctuating crude quality and compatibility issues elevate the importance and challenge to effective desalter operation. This paper will outline some of the quality variations in crudes, describe several methods to enhance desalter operation, and present case histories for improved desalter operation with today’s opportunity crudes. Adopting an integrated approach to refinery operations when processing opportunity crudes can help anticipate and negate many of the negative impacts to downstream units, such as the waste water treatment plant, as well as provide an opportunity to improve overall plant reliability, such as with the use of low salting boiler amines to minimize crude unit overhead amine salt corrosion potential.
