ABSTRACT:
Contaminants such as surfactants, antifoam agents, viscosifying agents, corrosion inhibitors, other agents used in tertiary recovery of enhanced oil recovery operations, and the like are removed from a contaminated feedstock stream by contacting said feedstock stream with an adsorbent selected from montmorillonite clays, amorphous silica, and mixtures thereof with one another and/or with bauxite. In a further aspect, the thus purified feedstock stream is hydrodesulfurized.
