Abstract
A composition and method for the removal of water from a water-containing hydrocarbon stream, and a method for the production of a metal/water-soluble polymer composite are provided. The composite includes a water-soluble polymer, such as guar gum, and a metal salt, such as aluminum nitrate or copper sulfate. The ratio of the metal salt to the water-soluble polymer is in the range from about 1:1 to about 5:1 by mass. The water-soluble polymer and the metal salt form a crosslinked material. The method for producing the metal/water-soluble polymer composite includes mixing a non-crosslinked water-soluble polymer with a metal salt and water to form a paste. The paste is then dried.
