Abstract: Fluid flow systems can include one or more thermoelectric devices in contact with the fluid flowing through the system. One or more thermoelectric devices can be operated in a temperature control mode and a measurement mode. Thermal behavior of the one or more thermoelectric devices can be analyzed to characterize a level of deposit formed on the thermoelectric device(s) from the fluid flowing through the system. Characterizations of deposition on thermoelectric devices operated at different temperatures can be used to establish a temperature-dependent deposition profile. The deposition profile can be used to determine if depositions are likely to form at various locations in the system, such as at a use device or in a flow vessel. Detected deposit conditions can initiate one or more corrective actions that can be taken to remove deposits, or to prevent or minimize deposit formation before deposits negatively impact operation of the system.

Abstract: Fluid flow systems can include one or more resistance temperature detectors (RTDs) in contact with the fluid flowing through the system. One or more RTDs can be operated in a heating mode and a measurement mode. Thermal behavior of the one or more RTDs can be analyzed to characterize a level of deposit formed on the RTD(s) from the fluid flowing through the system. Characterizations of deposition on RTDs operated at different temperatures can be used to establish a temperature-dependent deposition profile. The deposition profile can be used to determine if depositions are likely to form at certain locations in the fluid flow system, such as at a use device. Detected deposit conditions can initiate one or more corrective actions that can be taken to prevent or minimize deposit formation before deposits negatively impact operation of the fluid flow system.

Abstract: The invention is directed towards methods, compositions, and apparatus for accurately detecting the presence and amounts of contaminants in wastewater. The method comprises the steps of adding to a volume of wastewater at least one tracer molecule, observing the tracer for indications of particular contaminants, conducting at least one second form of contamination detection, and interrelating the two measured properties to identify the specific composition of the contamination. Using a tracer molecule allows for the detection of otherwise hard to detect oils and grease. Use of the second method however compensates for tracer interfering contaminants and allows for more accurate readings. The invention includes feeding of functional chemicals in response to the detections and conducting the detections online and continuously.

Abstract: Disclosed are methods and compositions for coagulating and clarifying produced waters for use as boiler feed waters, for example for the generation of steam. The methods and compositions are especially useful for treatment of produced waters from steam-injection methods of tertiary oil recovery such as steam-assisted gravitational drainage. Disclosed are compositions comprising a first copolymer having a high molecular weight and bearing a low molar cationic charge and a second copolymer having a lower molecular weight and bearing a high molar cationic charge. The compositions are suitable for addition as coagulants to produced waters that have been treated by warm lime softening. Also disclosed are methods of treating produced waters from steam-injection oil recovery for use as boiler feed waters to generate steam in such steam injection methods.

Abstract: A method of obtaining or maintaining optical transference into deaerated liquid in contact with a light transference medium is disclosed. The method comprises applying ultrasonic energy at a wavelength (λ) into deaerated liquid in contact with a light transference medium. The ultrasonic energy at wavelength (λ) originates at a distance (d) from an optical signal transmitted into the light transference medium. The distance (d) may be defined by a formula based on the wavelength (λ) of the ultrasonic energy.
