Patent number: 6984614Abstract: A composition for removing paraffin, wax, or asphaltine deposits from the surface of a crude oil transmission system, such as a downhole tubular, a pipeline, or a surface tank, includes an aqueous sodium hydroxide solution containing from 18% to 25% by weight sodium hydroxide. The composition further includes an acetic acid solution containing from 30% to 55% by weight acetic acid compared to the sodium hydroxide, and a liquid aromatic hydrocarbon having from 6 to 10 carbon atoms and from 15% to 40% by weight compared to the sodium hydroxide. According to the method of the invention, the aqueous sodium hydroxide solution may be metered in a downhole tubular or a pipeline separate from the acetic acid solution, such that heat generated by the mixed composition is generated within the downhole tubular or the pipeline.Type: GrantFiled: January 10, 2005Date of Patent: January 10, 2006Inventor: Jerome S.

Patent number: 6812195Abstract: The present invention is directed to a grease-cutting detergent composition that exhibits a stable foaming profile when used with non-enclosed automatic dishwashers. The composition can be sold in a concentrated form or in ready-to-use (RTU) diluted form. The concentrated compositions are formulated to be diluted with water before use. The RTU formulas are intended for as-is usage. In one embodiment the concentrated compositions comprises a) from about 0.25% to about 10% of a surfactant, b) from about 4% to about 8% of an alkalinity source, c) from about 0.1% to about 4.0% of a hydrotrope, d) from about 0.001% to about 2.0% of a builder, and e) from about 0.01% to about 3.0% of a thickener. In another embodiment an RTU formulation comprises a) from about 50 ppm to about 80 ppm of a surfactant, b) from about 45 ppm to about 75 ppm of an alkalinity source, c) from about 20 ppm to about 45 ppm of a hydrotrope, d) from about 0.Type: GrantFiled: September 16, 2002Date of Patent: November 2, 2004Assignee: The Procter & Gamble Co.Inventors: Thomas James Wierenga, James August Weikel
