Patent application numberDescriptionPublished
20080312983DYNAMIC RISK MANAGEMENT - Methods and systems of managing project risk in a business environment are provided. In the methods, the presence of mitigation solutions is taken into consideration prior to the occurrence of project-associated risks, thus minimizing negative impact when the risks occur. Project risk levels can be dynamically updated, thus allowing a user to capture and review accurate risk levels for multiple interdependent projects at any point in time.12-18-2008

Patent application numberDescriptionPublished
20120117254Methods, Devices and Computer Program Products for Actionable Alerting of Malevolent Network Addresses Based on Generalized Traffic Anomaly Analysis of IP Address Aggregates - Methods for providing alerts in a network are disclosed. Some methods include collecting network traffic data corresponding to multiple subsets of network addresses during a predefined time interval. A suspect subset of the subsets of network addresses that corresponds to anomalous network activity may be identified based on the network traffic data and using at least one of multiple anomaly detection metrics. A source network address within the suspect subset of network addresses that corresponds to the anomalous network activity is identified. An alert corresponding to the source network address may be generated.05-10-2012

20100028735PROCESS FOR CONVERTING METHANE INTO A HIGHER ALKANE MIXTURE - The present invention relates to a process for converting methane into a higher alkane mixture, preferably a liquid alkane mixture, comprising (C02-04-2010
20100089797Devices And Processes For Deasphalting And/Or Reducing Metals In A Crude Oil With A Desalter Unit - This invention relates to devices and processes for removing asphaltenes and/or metals from crude oil to increase refinery processing of heavy materials. The desalters of this invention reduce and/or remove at least a portion of asphaltenes and/or metals form the crude oil. The separation occurs by mixing water with the crude oil to result in an aqueous phase having water and water soluble salts, an interface phase having asphaltenes and/or metals along with water, and a hydrocarbon phase having desalted, deasphalted and/or reduced metal crude oil.04-15-2010
20100326880Hydrocarbon Conversion Process Additive and Related Processes - This invention relates to a hydrocarbon conversion process additive and related processes, such as upgrading a heavy hydrocarbon material and making sponge coke. The hydrocarbon conversion process additive works with thermal processes, catalytic processes, or thermal-catalytic processes. The hydrocarbon process conversion additive includes lignin or macromolecular substructures of lignin like para-coumaryl alcohol, coniferyl alcohol, or sinapyl alcohol.12-30-2010
20110005968Coking Process Additives and Related Processes - This invention relates to coking process additives and, related processes, such as upgrading heavy hydrocarbons, producing petroleum coke and lighter hydrocarbon products, and/or thermally cracking heavy hydrocarbons. The additive includes an anionic clay to increase a liquid product yield. Suitable anionic clays may include hydrotalcite materials and hydrotalcite-like materials.01-13-2011
