Latest Patents

Krehbiel holds a patent for a "Waterflood method using overbased normal alkylaromatic sulfonates." This invention involves an improved anionic waterflood additive that is prepared by partially chlorinating a normal alkane with about 10 to 18 carbon atoms. The process includes employing the chlorinated alkane to alkylate an aromatic hydrocarbon, such as benzene, and sulfonating the resulting alkylate to form a sulfonic acid. The sulfonic acid is then converted to a sulfonate by reacting with a base component, such as an alkali metal hydroxide or ammonium hydroxide. The sulfonate is overbased by mixing it with an excess of base component, allowing for effective injection into petroliferous formations to enhance oil recovery.
