Abstract: Techniques are disclosed for presenting users with dynamic views of process data related to the operations of an industrial system. Data obtained by a SCADA system may be stored in a real-time status database (which reflects the current process data of the industrial system) and a historian database (which archives the process data from the industrial system as it changes over time). A design canvas allows users to compose a dynamic view of the process data obtained by the SCADA system. For example, a user may compose a dynamic view of selected temperatures, pressures, and flow rates obtained by the SCADA system while monitoring the status of a pipeline.

Abstract: The present invention provides a process for recovering hydrogen and carbon dioxide from a process stream (1) of a process unit (0) wherein the process stream (1) contains at least carbon dioxide, hydrogen and methane. In the process, the process stream (1) is optionally compressing in a first compressor (2) before being cooled in a heat exchanger (3) to a temperature equal to or less than ?10° C. Next, the cooled process stream (1) is separated and purified in a carbon dioxide separation unit (4) to produce a carbon dioxide rich liquid stream (6) and a carbon dioxide lean non-condensable stream (5) with the carbon dioxide rich liquid stream (6) being withdrawn as a carbon dioxide product for further use.

Through the use of a combination of hydrogen selective membranes and carbon dioxide selective membranes together with a carbon dioxide separation unit it is possible to increase recovery of hydrogen and carbon dioxide and improved process efficiency of the hydrogen generation plant.

Abstract: The present invention relates to a process for the reduction of CO2 emissions from the flue gas of a cracking catalyst regenerator that is part of a fluidized catalytic cracking system which cracks petroleum feedstocks such as petroleum distillates of residual or crude oil which, when catalytically cracked, provide either a gasoline or a gas oil product. This process may also be utilized with regard to the cracking of synthetic feeds having boiling points of from 400° F. to about 1000 as exemplified by oils derived from coal or shale oil. By reducing the CO2 emissions in the regeneration step of catalytic cracking, the further goal of maximizing the production of CO in the flue gas is achieved, the CO being further utilized as a fuel in the refinery or further processed to produce hydrogen.

Abstract: Embodiments of the invention provide a computerized optimization system configured to optimize the operations of a hydrogen generation, processing, and delivery network. Such a network typically includes a complex of physical equipment, plants, and pipelines, including both production and distribution facilities. A hydrogen optimization system provides a software system that optimizes the production and distribution of hydrogen over such a hydrogen network. The hydrogen optimization system may use both a genetic algorithm configured to “evolve” a population of solutions to improve the quality of solutions over time as well as directed heuristics to identify a superior operating state for the hydrogen pipeline network.

Abstract: Techniques are disclosed for managing certain aspects of a large industrial operation (such as a pipeline). A commodity materials invoice system may allow a user to model a commodity invoice as a template and subsequently use that template to model commodity usage for different periods of time. Costs for a given billing period may be estimated based on actual commodity consumption. For example, data from a SCADA system monitoring different aspects of a pipeline may be used to estimate invoice costs for retail commodity consumption. The commodity materials invoice system may be configured to present both estimated and actualized invoice data side-by-side, allowing users to make a direct comparison of the estimated and actualized invoice data.

Abstract: A billing system for supply contrasts in an industrial network is disclosed. In the case of a pipeline, a process flow computer installed at each customer site may each receive instantaneous flow readings from a flow meter. The process flow computer may be configured to accumulate product volumes in different volume groups, where each volume group corresponds to a range of instantaneous flow rates. Different volume groups may be associated with different rates ultimately charged to a customer. The volume groups may be assigned by a computing system running a billing application at a pipeline operations control center. Volume groups may be set for individual customers based on a contract summary of an agreement between a given customer and the operator of an industrial network.

Abstract: A programmable logic controller (PLC) protocol converter is disclosed that allows a supervisory control and data acquisition (SCADA) system to effectively communicate with a PLC device using a desired communications protocol, particularly in cases where the PLC device does not “speak” the desired communications protocol. A first thread may be configured to continually read PLC addresses, one at a time, using a communications protocol understood by the PLC device. The first thread may store the data values in the shared data array within program memory. Thus, the first thread exposes data from the PLC device, as specified in the configuration file. At the same time, a second thread may be configured to serve the data in the shared data array according to a second communications protocol, e.g., to the SCADA system.

Abstract: Techniques for operating an archival database, referred to as a historian, are disclosed. The historian may be used to archive values from a real-time database. Data values to be archived in the historian are first written to a short-term, high-availability repository, such as a memory-mapped database. As data values “fill” the short-term repository, an archival processor application may be configured to “drain” them from the short-term repository and store them in a high-capacity, long-term archive, such as a disk-based database. Thus, the short-term repository may be used to provide fast access to the recent operational history of a monitored system, (e.g., a complex pipeline network), where long-term archive may be used to provide access to a comprehensive operational history of the monitored system.

Abstract: Techniques for operating an archival database, referred to as a historian, are disclosed. Embodiments of the invention provide techniques for synchronizing historical archive files and/or archival data between a primary and a secondary historian used to archive data values from a real-time database. The real-time database may be used to monitor the current operational state of a large industrial system, such as a pipeline. In turn, the historian may be used to archive the data stored by the real-time database. In the event that either the primary or the secondary system (or both) goes down and then comes back online at a later time, embodiments of the invention may be used to synchronize data between the primary and secondary historian systems.
