A process for removing contaminants and breaking emulsions in a feedstream comprising a crude source composition comprising unconventional or opportunity crude oil, the process comprising: providing the feedstream comprising the crude source composition comprising unconventional or opportunity crude oil, the feedstream comprising an emulsion comprising one or more contaminants, a salt content, and a water content; and, contacting the feedstream directly with one or more mesopore structured materials and one or more demulsifiers under conditions effective to separate a majority of the water content, the salt content, and the one or more contaminants from the feedstream, thereby breaking the emulsion and producing a purified hydrocarbon phase.
