The invention relates to a method for producing acidification oil by using oil footings and/or soapstocks. The method comprises the step of enabling oil footings and/or soapstocks to be contacted with carbon dioxide and water. Compared with the prior art, the method provided by the invention has the advantages that a CO2 water solution with high concentration is adopted to replace sulphuric acid to perform an acidification reaction of oil footings and/or soapstocks, and the like, a side reaction can not be induced, no sour odor exists in a production field, and the quality of an acidification oil product produced is good; for example, acidification oil produced by the embodiment of the invention is reddish-brown transparent liquid, and the content of a saponated matter is as high as more than 90w%; however, acidification oil produced by a sulphuric acid method of the prior art according to a proportion 1 is a pitchy non-transparent gelatinous matter, and the content of a saponated matter ...

The invention relates to a refining method of acidification oil. The refining method comprises the following steps: acidification oil contacts with an ultrafiltration membrane, the acidification oil is pressurized to enable saponated substances in the acidification oil to pass, and unsaponifiable substance impurity with the granule diameter greater than 1 micron is interrupted. According to the method provided by the invention, the saponated substances in the acidification oil can pass by enabling the acidification oil to be contacted with the ultrafiltration membrane and pressurizing the acidification oil, an impurity with greater granule diameter can not pass, the quality of the acidification oil can be improved, and the refining method can be directly used for the production of biodiesel; for example, the content of the saponated substances in the acidification oil obtained can be increased to more than 95w%, the moisture content is reduced to less than 1.5w%, and the content of a mechanical ...
