  • NONYLPHENOL ETHOXYLATE-FREE OIL DISPERSANT FORMULATION
    Publication number: 20180355284
    Abstract: Nonylphenol ethoxylates (NPEs) have been used as surfactants in a wide variety of household products and industrial applications. Despite their effectiveness as surfactants, NPEs can accumulate in the environment and adversely affect aquatic organisms. The dispersants of the present disclosure can be used to disperse oil and/or microbes while avoiding the adverse effects of NPEs. Oil and microbial fouling is of particular concern in refinery cooling towers where the water may be contaminated with oil and microbial growth can cause cooling inefficiencies among other problems. The dispersant may include an oil dispersant comprising a C6-C20 alcohol ethoxylate, a bio-dispersant comprising a copolymer of ethylene oxide and propylene oxide, and 2-butoxyethanol. The oil dispersant, the bio-dispersant, and the 2-butoxyethanol form a dispersant solution, and the solution does not include a nonylphenol ethoxylate.

  • Method of tracing chemical quantities using encapsulated fluorescent dyes
    Patent number: 10139385
    Abstract: The invention provides methods and compositions for utilizing encapsulated tracer dyes in difficult liquids such as wastewater or with highly reactive treatment chemicals such as aluminum-based coagulants. In difficult liquids or highly reactive treatment chemicals even so-called “inert” tracers end up reacting and their fluorescence changes. As a result they are inconsistent and cannot be used to measure the amount of treatment chemical present. But by encapsulating the tracer dyes, even non inert tracer dyes become inert and they can reliably be used to measure the amount of treatment chemical present even if highly reactive or in a difficult liquid.

  • Fluid flow meter with normalized output
    Patent number: 10139258
    Abstract: A fluid flow meter is described, that includes intermeshing gears that may rotate synchronously. The fluid flow meter may produce a pulsed output that can be normalized to suitable values according to a method of normalizing input pulses generated in response to the rotation of gears. A volume counter can be incremented by an amount equal to a volume per input pulse each time an input pulse is generated. When the volume counter exceeds a first reference volume, a normalized output pulse can be generated until the volume counter exceeds a second reference volume.
