Abstract
A method for processing an acidic hydrocarbon feed comprising a hydrocarbon material and an acidic constituent soluble in the feed is provided. The method may comprise contacting the feed under a first condition with an active agent having an initial solubility in the feed and the acidic constituent and providing a second condition wherein the active agent has a secondary solubility in the feed lesser than the initial solubility to form a separable enriched active agent phase. The acidic constituent solubility in the active agent may be greater than its solubility in the hydrocarbon material under both the first and second conditions such that the acidic constituent dissolves in the active agent. The acidic constituent solubility in the active agent under the second condition may be greater than its solubility in the active agent under the first condition. The method may further comprise separating the enriched active agent phase from the hydrocarbon material depleted in the acidic constituent under the second condition.
