Abstract

The invention discloses a method for removing organic chlorine in a liquid oil product. The method comprises the steps that a demulsifier, an alkaline compound, an antichlor and the oil product are mixed, a dechlorination reaction is conducted, and water is injected after the dechlorination reaction; in the environment that the heating temperature is 80-150 DEG C, and oil-water separation is conducted; the alkaline compound is a water-soluble organic amine compound and / or an inorganic alkaline compound; the antichlor is obtained by compounding, by mass, 3-5 parts of a phase transfer catalyst,8-15 parts of alkali and 55-75 parts of a solvent, wherein the phase transfer catalyst is quaternary ammonium base or polyethylene glycol. Accordingly, by using the alkaline compound and the antichlor, the organic chloride in the liquid oil product can be effectively removed, the temperature needed by a dechlorination reaction is lowered, the time needed by the dechlorination reaction is shorter,and the industrial use value is better achieved.

Description

technical field [0001] The invention relates to the technical field of removing organic chlorine, in particular to a method for removing organic chlorine in oil products. Background technique [0002] Chlorine elements in lubricating oil and chlorides in crude oil generally exist in two forms, one is organic chlorine in chlorinated alkanes, and the other is inorganic chloride formed by alkaline earth metals. The main reason why chlorine corrosion occurs frequently is that only most of the inorganic matter can be removed during the electric desalination process, and most of the chlorine-containing organic matter remains in the waste lubricating oil and enters the subsequent device, causing poisoning of the device catalyst . In the subsequent catalytic hydrogenation process, organic chlorides will produce HCl, and N-containing substances may produce NH3, resulting in the combination of HCl and NH3 to form NH4Cl, causing pipeline blockage and affecting the service life of equi...
