  • Publication number: 20170298293
    Abstract: Provided are methods to destabilize emulsion feedstocks. Benefits of the provided methods include a reducing or eliminating the amount of acid necessary to process the feedstocks, less processing time, cleaner separation of the resulting phases, and increased recovery of valuable products. In the methods, a moderate temperature is applied to the feedstock to create a first mixture. The moderate temperature may be between 120 and 220 degrees Celsius. The first mixture is mixed at the moderate temperature, such as by staged mixing in some embodiments. Moreover, the first mixture is retained at the moderate temperature for up to six hours. The first mixture is separated into an oil phase, convoluted phase, and a water phase. In some embodiments, the moderate temperature may be 125 to 150 degrees Celsius, such as between 125 and 130 degrees Celsius. Moreover, the first mixture may be retained at the moderate temperature for between forty-five minutes and four hours, such as from two to four hours.
