It provides for processing a dehydrated and salty hydrocarbon feed having a solid salt dispersed in a hydrocarbon material by contacting the feed with an active agent under a first operating condition under which the active agent has an initial active agent solubility in the hydrocarbon material, and modulating operating conditions to provide a second operating condition under which the active agent has a secondary active agent solubility in the hydrocarbon material that is less than the initial active agent solubility so as to form a separable active agent phase, wherein the salt solubility in the active agent is substantially greater than the salt solubility in the hydrocarbon material under both the first and second operating conditions such that the salt dissolves in the active agent, allowing the separable active agent phase to separate from the hydrocarbon material depleted in the salt.
