Abstract: Various methods and systems are directed to a mislinked meter system that identifies utility meters mislinked to a distribution transformer in a data store. Utility meters reporting voltages that vary more than other meters linked to the same distribution transformer in the data store may be physically linked to a different distribution transformer. To compare meter voltages, the mislinked meter system generates normal meter errors for the utility meters and a normal transformer error for some or all of the utility meters linked to the same distribution transformer. The normal meter error and transformer error represent the amount the voltages of a utility meter varies from the voltages of the other utility meters associated with the distribution transformer. The more the meter errors vary when compared to the transformer error, the more likely a utility meter is mislinked to the wrong distribution transformer in the data store.

Abstract: Disclosed are various embodiments for locating utility metering devices. Utility metering devices are those that are lost or stolen and that are facilitating unauthorized utility service access. Many AMI and/or AMR deployments lack the ability to remotely deactivate a meter. Accordingly, embodiments of this disclosure can generate a zone of interest in which an unauthorized utility metering device is located, and the unauthorized utility metering device can be subsequently located within the zone of interest.

Abstract: A regenerator that can handle rich loaded chemical solvent containing precipitated absorption reaction products is disclosed. The invention is particularly suitable for separating CO2 from large gas streams that are typical of power plant processes. The internally circulating liquid stream in the regenerator (ICLS regenerator) rapidly heats-up the in-coming rich solvent stream in a downcomer standpipe as well as decreases the overall concentration of CO2 in the mixed stream. Both these actions lead to dissolution of precipitates. Any remaining precipitate further dissolves as heat is transferred to the mixed solution with an inverted bayonet tube heat exchanger in the riser portion of the regenerator. The evolving CO2 bubbles in the riser portion of the regenerator lead to substantial gas hold-up and the large density difference between the solutions in the downcomer standpipe and riser portions promotes internal circulation of the liquid stream in the regenerator. As minor amounts of solvent components present in the exit gas stream are condensed and returned back to the regenerator, pure CO2 gas stream exits the disclosed regenerator and condenser system.

Abstract: A second stage gasification unit in a staged gasification integrated process flow scheme and operating methods are disclosed to gasify a wide range of low reactivity fuels. The inclusion of second stage gasification unit operating at high temperatures closer to ash fusion temperatures in the bed provides sufficient flexibility in unit configurations, operating conditions and methods to achieve an overall carbon conversion of over 95% for low reactivity materials such as bituminous and anthracite coals, petroleum residues and coke. The second stage gasification unit includes a stationary fluidized bed gasifier operating with a sufficiently turbulent bed of predefined inert bed material with lean char carbon content. The second stage gasifier fluidized bed is operated at relatively high temperatures up to 1400° C. Steam and oxidant mixture can be injected to further increase the freeboard region operating temperature in the range of approximately from 50 to 100° C. above the bed temperature.

Abstract: A pressurized transport oxy-combustor with different configurations is disclosed. Substantially pure oxygen is fed to the transport oxy-combustor under pressure to combust fossil fuels, generating steam for power generation. The end product is the flue gas containing substantially pure CO2 after moisture condensation. The low excess oxygen necessary to achieve complete combustion in the combustor is scavenged by adding another fuel so that substantially all oxygen fed to the combustor is completely consumed. The capability to operate the transport oxy-combustor as a circulating fluidized bed combustor at very high solids circulation rates makes it unnecessary to use recycled CO2 or flue gas as a means to moderate and control the combustion temperature. The temperature in the combustor is effectively controlled by relatively cooler circulating solids that enter the combustion zone. A small amount of CO2 is recycled for aeration and to convey solids fuel to the combustor.
