Neutralization of the emulsion high total acid number of (TAN) crude oil

摘要

This invention is a method for reducing the total acid number of the oil containing an organic acid. Forming a water-in-oil emulsion slurry / or hydrocarbon oil group VIIA metal hydroxide solution, wherein the oil-in-water emulsion, a process having an aqueous droplet particle size diameter 1~25μ, the method, the oil case and a step of standing time sufficient to neutralize the organic acids in the petroleum, a mixture of a step of adding to the oil containing an organic acid, a medium-water emulsion.
