Corrosion inhibitor and kinetic hydrate inhibitor formulations, and methods of using each are provided. Each formulation optionally includes a fluorophore, which can be used to fluorometrically control dosage of each formulation into an aqueous liquid utilized in a downhole application, thereby providing improved precision of dosage into aqueous liquids having relatively high turbidity, and consequently relatively high light absorbance.

Corrosion inhibitors and kinetic hydrate inhibitors

Disclosed is a method of monitoring and optimizing the concentration of an additive composition in a fuel ethanol. The method includes adding a known amount of the additive composition to the fuel ethanol to create a treated fuel ethanol. A measured fluorescent signal provides information for determining the concentration of the additive composition in the fuel ethanol. A component in the additive composition is capable of providing the fluorescent signal or capable of being chemically derivatized to provide a fluorescent signal or a colorimetric signal. Based upon the measured fluorescent signal or colorimetric signal, the concentration of the additive composition in the fuel ethanol may be adjusted.

Method of monitoring and optimizing additive concentration in fuel ethanol

The present invention generally relates to methods for removing an organic deposit or for inhibiting deposition of deposit-forming comprising contacting a cleaning composition or an anti-coking composition with a surface. The surface can have an organic deposit or be susceptible to forming an organic deposit and the surface can be in contact with a liquid containing organics. The liquid can be produced from a thermal recovery system, and the surface can be an internal surface of a piece of steam-generating or vapor-generating equipment.
