The present invention, processing of a hydrocarbon feedstock comprising a crude oil, and relates to a field that is a metal, such as calcium removed here. To be forced in the face of price increase of the crude oil, refining sleep to process lower quality crude oil (opportunity crudes) as DOBA, wherein low-quality oil is a number, including fouling (fouling) of the device due to the particular metallic salt such as calcium naphthenate It has the problem. Conventional calcium can not be removed from the crude oil during the desalination process has a very serious problem. The present invention is to provide a process for the removal of calcium, wherein the oil is an effective metal removal amount of an additive comprising a chemical compound selected from the group consisting of metal acid, maleic anhydride, fumaric acid, or their salts or derivatives, be mixed with the extraction solution, it is possible to separate the aqueous phase and a hydrocarbonaceous phase containing metal ions from the desalination apparatus. Only calcium-free hydrocarbonaceous sangman this is further processed, leading to fouling of the equipment is prevented.
