Abstract: A system (700) for using a vapor pressure to determine a concentration of a component in a multi-component fluid is provided. The system (700) includes an electronics (710) communicatively coupled to a transducer (720) configured to sense a multi-component fluid. The electronics (710) is configured to determine a first vapor pressure, the first vapor pressure being a vapor pressure of a first component of the multi-component fluid, determine a second vapor pressure, the second vapor pressure being a vapor pressure of a second component of the multi-component fluid, and determine a multi-component vapor pressure, the multi-component vapor pressure being a vapor pressure of the multi-component fluid. The electronics (710) is also configured to determine a concentration of at least one of the first component and the second component based on the multi-component vapor pressure, the first vapor pressure, and the second vapor pressure.

Abstract: A vibratory meter (5) for determining a vapor pressure of a fluid is provided. The vibratory meter (5) includes a meter assembly (10) having a fluid, and a meter electronics (20) communicatively coupled to the meter assembly (10). The vibratory meter (5) is configured to determine a vapor pressure of the fluid in the meter assembly (10) based on a static pressure of the fluid in the meter assembly (10).

Abstract: A meter electronics (20) for using a density measurement of a fluid to verify a vapor pressure is provided. The meter electronics (20) includes a processing system (200) communicatively coupled to a meter assembly (10) having the fluid, the processing system (200) is configured to determine a vapor pressure of the fluid by detecting a phase change of the fluid in the meter assembly (10), measure a density of the fluid based on a resonant frequency of the meter assembly (10), derive a vapor pressure from the measured density, and compare the determined vapor pressure with the derived vapor pressure.

Abstract: A meter electronics (20) for determining a vapor pressure using a vapor pressure meter factor is provided. The meter electronics (20) comprises a processing system (200) communicatively coupled to a meter assembly (10). The processing system (200) is configured to provide a drive signal to the meter assembly (10) having a fluid, measure a drive gain of the drive signal provided to the meter assembly (10), and determine the vapor pressure of the fluid based on a previously determined relationship between the drive gain and a reference gas-liquid ratio.

Abstract: A device for installing horizontal drains in a coal combustion residual or other sludge pond consists of a trenching device that extends downwardly to the depth of required installation of the drains and an attachment through which the drains are fed during installation. The trenching device and attachment are mounted onto a carrier for floatation of the required equipment on the surface of a water-filled sludge pond. The carrier can be winched, hauled or driven across the surface of the sludge. A hydraulic system may be used to raise and lower the trenching device and attachment. The trenching device may be equipped with a chain driven blade mechanism or dredging device for the purpose of cutting a trench into the pond sludge, and a vibratory trenching device may be used to effectively liquefy the material to make the trenching device easier to pull or tow through the sludge in the pond.
