Abstract: The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.

Abstract: The invention provides methods and compositions for softening paper. An inventive composition and method of its use softens paper products (like tissue paper) by de-bonding its cellulose fibers and by improving the smoothness of the resulting paper. The invention forms a surfactant-polymer complex that attaches de-bonding non-ionic surfactants to cellulose fibers that would otherwise not be retained by the cellulose fibers. This complex prevents the fibers from bonding with each other and makes the paper product smoother. Best of all, the composition is environmentally superior and is a non-toxic.

Abstract: An apparatus and method for measuring and monitoring the corrosion potential of engineering alloys used in aqueous systems is disclosed and claimed. The method is applicable for a variety of alloys including, but not limited to, copper-based, iron-based, nickel-based, other metallic-based alloys, and their combinations. The corrosion potential is typically determined by measuring a voltage between a specific material in the described oxidation-reduction potential measuring device and a reference electrode. Corrosion potentials for specific materials of construction may be used for diagnostic or control purposes.
