Abstract
A continuous process of contacting crude oils, particularly triglyceride oils, with an acid for the purpose of removing phosphatides and trace metals is disclosed. The acid is introduced into a stream of heated oil immediately ahead of mixing means, such as a static-mixer, capable of achieving an acid droplet size smaller than 10 microns in diameter. The interfacial surface provided by these microscopic droplets allows the acid-oil contacting process to occur essentially instantaneously, requiring less acid and less acid-oil residence-time. The process is useful in treating crude oils prior to alkali-refining or prior to a bleaching treatment in preparation for steam-refining.
