To provide a method for purifying hydrocarbons.SOLUTION: The method includes flowing an aqueous phase 108 comprising water into a first end of a mixing zone 110 of a reactor 102 along a first direction. Organic phase 114 is mixed with aqueous phase 108 via counter-current flow by flowing organic phase 114 into a second end of mixing zone 110 opposite the first end. The organic phase 114 includes oils, fats, greases, or combinations thereof from plant and / or animal sources. The flow of the organic phase 114 is along a second direction opposite to the first direction, and the organic phase 114 comprises at least contaminants comprising halides, phosphorus, sulfur, alkali metals, metalloids, heavy metals, or any combination thereof. The mixing region 110 is heated. The purified organic phase 114 is extracted from the purification zone of the reactor 102. Waste is extracted from the waste area of the reactor 102.SELECTED DRAWING: Figure 4

This document provides systems and methods for limiting gum formation in pyrolysis oils and removing gum impurities from pyrolysis oils during storage and / or transportation, as well as improved techniques for removing gum deposits from the inner surfaces of sealed containers during storage and / or transportation. One such method includes loading a sealed container with a dispersant, which is a polar surfactant immiscible with the pyrolysis oil. The steps include contacting the pyrolysis oil with the dispersant inside the sealed container to produce a stabilized pyrolysis oil and form water-dispersible gum deposits on the inner surface of the sealed container. In some examples, after removing the stabilized pyrolysis oil from the sealed container, the step includes applying an aqueous fluid to the inner surface of the sealed container to disperse and remove the water-dispersible gum deposits from the inner surface of the sealed container.
